Description

The invention relates to a track crossing unit between a ballast track section and a ballastless track section.

At level crossings, bridges or the like track bodies are usually formed by a ballastless track section. Often follows on both sides of this ballastless track section each a gravel track section of the track body. The support of the rails in the ballastless track section and in the ballast track section is different from each other. Due to external influences and the load, for example when driving over the track body with rail vehicles, therefore, different changes occur in the ballast track section and in the ballastless track section. In the event of changes in the rail position, in particular a rail level in a height direction in the ballast track section, the ballast of the ballast bed is stuffed (compressed or stabilized) for the maintenance of the ballast track section. Special tamping machines are used to lift the rails and sleepers and compact and stabilize the underlying ballast bed. This usually changes the rail level in the height direction. The plugging of the ballast track with machines provided for this purpose is only possible up to a certain distance from the ballastless track section, since the rails are firmly anchored in the ballastless track section and therefore lifting of the rails and sleepers in the ballast track section is not possible up to the edge of the ballastless track section. This complicates the mechanical maintenance of the ballast bed.

Another problem is the different length and position changes in the ballast track section and in the ballastless track section from each other due to environmental influences, in particular due to changing temperatures.

In order to solve the above-mentioned problems, according to the present invention, there is provided a track body transfer unit for a track body which is disposed between a ballast track section and a ballastless track section of the track body.

The track body has at least two rails, so that a longitudinal section of the at least two rails extends along the track body transition unit. The track transition unit has a base body, which may be formed in particular by a concrete body. The concrete body can be manufactured as a casting factory or on site. In addition to the main body, the track body transition unit can also have further separate additional basic bodies, which are arranged next to one another in the direction of the rail track. The main body has a bottom and a bottom opposite the top. With the underside of the main body is arranged on a surface outside of the ballastless track section. The substrate is preferably the substrate on which the ballast bed of the ballast track section is applied. The substrate is, for example, a surface protection layer (PSS) or antifreeze layer (FSS). Between the underside and the substrate, an intermediate layer for adjusting the height of the base body may be arranged, which is formed for example by grit, in particular hard stone Edelsplitt.

At the top of the main body carries a first rail holding device. The first rail holding device is set up to respectively hold and store a rail section of the rails. The first rail holder is also adapted to allow a rail level change in a height direction perpendicular to the ground. As a result, the track transition unit provides the possibility of being able to change the track level in the ballast track section as far as the track transition unit. The lifting of the rails is made possible by the first rail holding device also in the immediately adjacent end region of the ballast track section. Thereby, e.g. a repair of the ballast bed up to the track transition unit zoom possible, for example, the mechanical plugging of the ballast bed. The track transition unit has a length in the rail running direction, which ensures a sufficient distance of the first rail holder from the ballastless track section, so that the lifting of the rails on the one hand is possible and on the other hand, no excessive loads or damage to the rail support in ballastless track section occur.

Preferably, the track transition unit connects on the one hand directly to the ballast track section. The main body and / or any additional base body is arranged at a short distance from the ballastless track section, which corresponds at most to a maximum allowable support distance between two immediately adjacent support points of the rail. For example, the distance may be at most as large as the support distance between two immediately adjacent thresholds in the ballast track section.

The first rail holding device preferably has at least two upwardly open receiving grooves, which are arranged on the base body. Each receiving channel is open at both ends in the rail running direction. The rails Thus, starting from the ballast track section, they can extend into the receiving channel at one end and out of the receiving channel towards the ballastless track section at the other end. Preferably, the receiving grooves are arranged in longitudinal recesses in the base body. Each receiving channel can receive a first rail section of the respective associated rail. It is advantageous if the first rail section is mounted movably in the vertical direction in the respective receiving channel. The first rail section is thus displaceable in the height direction or tilted or tilted relative to the respective receiving channel.

In addition, the first rail section may be movably mounted in the direction of travel of the rail, for example displaceably mounted.

It is advantageous if each arranged in a receiving channel first rail portion is fixed to a sliding bearing body. In this case, the plain bearing body is in particular immovably fixed to the first rail portion, preferably by an adhesive bond. The plain bearing body is movably guided guided within the receiving channel in the height direction and / or rail running direction. The sliding bearing body forms with the associated receiving groove a sliding bearing for guided movement of the sliding bearing body together with the first rail section. The guide is preferably designed such that the plain bearing body can be inclined about an axis extending in the transverse direction. Preferably, three degrees of freedom are thus allowed by the guide and allowed the movement in other degrees of freedom only in the context of existing elasticities or leadership games.

It is preferred if the plain bearing body has a width in a transverse direction at right angles to the rail running direction and at right angles to the height direction, which width corresponds to the width of the receiving groove. In one embodiment, the receiving channel has a substantially rectangular cross-section. In the transverse direction, the plain bearing body has two transversely opposite side surfaces, each resting against an inner wall of the receiving channel.

In particular, the plain bearing body may be formed as a cast body.

The base body may have an inclined surface on its side facing the ballast track section, at least in an inner region between the at least two rails. The inclined surface runs from the gravel track section obliquely inclined in the height direction, so that the height of the body increases away from the ballast track section. In particular, in freight trains, it may happen that parts hang down, such as clutches. The inclined surface of the impact or contact between the hanging parts and the body is mitigated to avoid damage to the body. Suspended parts slide along the inclined surface and are gently lifted.

In a preferred embodiment, the base body in an inner region between the at least two rails may have a projecting elevation in the height direction. The casserole projection has a width in the transverse direction which decreases in the direction of the ballast track section. In plan view of the top of the main body of the casserole in one embodiment has a wedge shape. In the case of a derailment at least one of the wheels of a rail vehicle runs on the casserole projection and is guided during the movement along the casserole projection back toward the associated rail.

It is also advantageous if the base body has at least one transverse groove extending in a transverse direction. The transverse channel bottom of the transverse channel is arranged in the height direction below the rails and in particular at a distance from the rail feet. The at least one transverse channel is arranged in particular closer to the ballastless track section than on the ballast track section. The transverse channel may for example be designed for draining the ballastless track section and / or provide installation space, for example for laying cables and / or pipes and / or electrical equipment.

It is advantageous if the at least one transverse channel is at least partially or completely covered at least in the inner area between the at least two rails and / or is partially or completely filled up with a water-permeable bed. As a result, it is possible to prevent parts hanging from a train from penetrating into the transverse channel and striking against the edge or the wall of a transverse channel.

In a further preferred embodiment, the first rail holding device may have a plurality of detachable rail fasteners arranged on the main body. The rail fasteners represent separate individual support points in the direction of rail travel for supporting the rail. The rail fastenings are designed to allow level adjustment in the vertical direction. It is therefore possible to change the rail level in the ballast track section, in particular when plugging the ballast bed. These can be the rail fasteners For example, be solved and fixed after repairing the ballast bed again on the changed height level. For example, for this purpose shims with different thicknesses and / or in a suitable number of each rail fastening can be used. Such rail fasteners as individual bases are known per se.

It is preferred if the first rail holding device is arranged on a first part of the base body adjoining the ballast track section. A second rail holding device may be arranged on a second part of the base body adjoining the ballastless track section. The two rail holders may differ from each other in terms of the guidance and support of the rail. For example, the second rail holding device may be adapted to be absorbed by external influences, such as changes in temperature, resulting level changes or changes in length of the rail in the ballastless track section.

The second rail holding device may be arranged in a preferred embodiment between two transverse grooves.

As explained, the track body transition unit may have, in addition to the base body, at least one additional base body, wherein the at least one additional base body is arranged between the base body and the ballastless track section. With the help of the at least one additional base body, a modular construction of the track transition unit can be achieved. The additional base body is preferably designed as a concrete body. The at least one additional basic body has on its upper side at least one third rail holding device. The third rail holder may be identical to or different from the first rail holder. In addition, the second rail holding device may be provided on the additional base body in addition to the third rail holding device.

Corresponding to the base body, the at least one additional basic body may have at least one transverse channel, which may have the same features as explained above in connection with the basic body. The second rail holding device may be arranged adjacent to a transverse channel or between two transverse channels on the base body or on an additional base body which directly adjoins the ballastless track section.

In the 1 to 4 is a first embodiment of a track transition unit 10 illustrated. The track crossing unit 10 forms a transition section of a track body between a gravel track section 11 and a ballastless track section 12. The ballastless track section 12 may be, for example, a railroad crossing, a bridge or a railway overpass. The ballastless track section 12 can in the execution as a railroad crossing or bridge a structure 13 which is exemplified in 1 is shown schematically. The ballastless track section 12 Alternatively, it can be made passable if, for example, it forms a railroad crossing (for example 2 and 3 ).

In the ballastless track section 12 is a supporting body 14 with at least two in a rail running direction S extending gutters or troughs 15 available. Every trough 15 like nut extends completely through the support body 14 , In every trough 15 a rail 16 of the track body is added. In 1 are the rails 16 only schematically illustrated by its cross section. The track body has at least two and in the embodiment exactly two rails 16 , The two rails 16 extend from the gravel track section 11 continuous through the track transition unit 10 into the ballastless track section 12 , It is understood that every rail 16 from several in track direction S can be formed abutting rail parts. The rails 16 have in a transverse direction Q perpendicular to the track direction S a distance corresponding to the track width of the track body.

In the troughs 15 are the rails 16 firmly arranged by means of a Schienenvergusses and relative to the troughs 15 or the support body 14 immobile. The supporting body 14 is preferably a concrete body.

In the gravel track section 11 are the rails 16 on sleepers 17 attached. The thresholds 17 are in a ballast bed 18 stored on a surface 19 is applied. The underground 19 is formed in particular by a surface protection layer PSS or antifreeze layer FSS.

The underground 19 runs in the embodiment of the gravel track section 11 at least until the ballastless track section 12 or, depending on its design, also in the ballastless track section 12 into it, as exemplified in 3 is illustrated. In the transition section between the ballast track section 11 and the ballastless track section 12 is the track transition unit 10 arranged and closes, for example, directly to the ballastless track section 12 and the gravel track section 11 at.

The track crossing unit 10 has a basic body 25 , which is formed in the embodiment as a concrete body. The main body 25 can be cast or produced on site or at the factory and placed on the ground 19. Preferred is an intermediate layer 26 between the main body 25 and the underground 19 available. With a bottom 27 the basic body is supported 25 For example, on the intermediate layer 26 and thus indirectly on the ground 19 from. The intermediate layer 26 may be formed, for example, as a hard stone splintered layer. The intermediate layer 26 serves the position of the main body 25 in a height direction H to adjust. The height direction H is perpendicular to the track direction S and perpendicular to the transverse direction Q aligned. The height direction H runs, for example, at right angles to the ground 19 , The height direction H can be oriented substantially vertically.

On the bottom 27 opposite top 28 the body has in one to the gravel track section 11 adjacent first part 29 a first rail holding device 30 , The first rail holding device 30 is designed to be the rails 16 at the base body 25 to store. The first rail holding device 30 is also adapted to a rail level change in the height direction H at the track transition unit 10 and at least in the first part 29 of the basic body 25 to enable. Thus, the rails can 16 in the area of the first rail holding device 30 in the height direction H be changed in their position. Due to this configuration of the first rail holding device 30 it will allow the rails 16 while maintaining the ballast bed 18 in the gravel track section 11 lift and the ballast bed up to the track transition unit 10 to stuff. For this purpose, known machines and methods are used. Due to the fact that the track transition unit 10 moving the rails 16 in the height direction H allows the plugging of the ballast bed 18 until immediately to the track transition unit 10 allows.

In contrast to the track transition unit 10 are the rails 16 in the ballastless track section 12 in the height direction H fixed and not positionable. Therefore, it has been difficult so far the ballast bed 18 following the ballastless track section 12 maintain. By using the track transition unit according to the invention 10 is a possibility created the ballast bed 18 to stuff up directly to the track transition unit 10 with conventional measures efficiently. The maintenance work of a track body with gravel track sections 11 and ballastless sections 12 , For example, bridges or level crossings is significantly simplified.

The first rail holding device 30 the track body transition unit 10 each holds a first rail section 16a the rails 16 in the area of the first part 29 of the track body. In the in the 1-4 illustrated embodiment, the first rail holding device 30 for this at least two upwardly open receptacles 31 , The receptions 31 are at the base body 25 arranged and according to the example in each case a groove-shaped base recess 32 arranged or by a groove-shaped base recess 32 educated. In the embodiment, the receiving channel 31 through a gutter outer wall 33 , a gutter inner wall 34 and a gutter floor 35 formed the gutter outer wall 33 and the gutter inner wall 34 connects with each other. The gutter outer wall 33 , the gutter inner wall 34 and the gutter floor 35 can be welded together or otherwise firmly connected together. The receptacle 31 can also be made integrally. As an alternative to the illustrated embodiment, a separate channel bottom 35 also omitted and by the reason of the basic body recess 32 be formed.

The receptacle 31 is preferably made of steel or a metallic alloy.

At the gutter outer wall 33 and the gutter inner wall 34 are a plurality of anchors 36 fastened, for example, by welding, resulting in the building material of the body 25 extend into it and the receiving channel 31 anchor in the base body 25. In track direction S are each several anchors 36 spaced apart and with the respective wall 33 . 34 connected. The anchors have in the embodiment of a rod-like shape with an enlarged head at the free end.

In the embodiment is for receiving each rail 16 a separate receiving channel 31 available. Each recording channel 31 is in track direction S open at both ends. This allows the respective rail 16 from the ballast track section 11 into the receptacle 31 into and out of the receiving channel 31 into the ballastless track section at the opposite end 12 extend. As it is in particular in the cross-section of 4 is illustrated has the gutter outer wall 33 in the height direction H a greater height than the gutter inner wall 34 , The two rails 16 limit in the transverse direction Q an interior area 37 , The gutter inner walls 34 are inside the interior 37 arranged while the gutter outer walls 33 in the transverse direction Q outside the interior 37 on the other rail 16 a side facing away from a common track are arranged.

The first rail section 16a is in the respective assigned receiving channel 31 in the height direction H movably mounted and in particular displaceably guided. In addition, the first rail section 16a in the receptacle 31 in track direction S be slidably guided guided. The first rail section 16a For example, it may also be inclined about a transversely extending axis, for example by adjusting its altitude differently at different locations. Movements in other degrees of freedom are apart from the elasticity of the first rail holder 30 and in particular of the plain bearing body 42 and the existing plain bearing play prevented.

In the illustrated here first embodiment according to the 1 to 4 is in every receptive sense 31 a plain bearing body 42 slidably guided guided. The plain bearing body 42 is according to the example at least in the height direction H opposite the receiving gob 31 displaceable and, according to the example, also in the direction of the rail S slidably arranged. The plain bearing body 42 supports both the gutter outer wall 33 , as well as on the gutter wall 34 from. He preferably has in the transverse direction Q two oppositely arranged side surfaces 43 , each at the associated gutter outer wall 33 gutter inner wall 34 issue. The side surfaces 43 are preferably designed as a flat side surfaces and aligned parallel to each other. The plain bearing body 42 is fixed to the respective first rail section 16a connected. The plain bearing body 42 is relative to the first rail section 16a immobile.

The plain bearing body 42 can be formed by a cast body. In the plain bearing body 42 can empty pipes 44 and / or a damping band 45 be poured. The damping band 45 is in the area between the rail foot of the first rail section 16a and the channel bottom 35. The empty pipes 44 and the damping band 45 are optional and can be omitted.

The width of the plain bearing body 42 corresponds apart from a technically necessary plain bearing clearance of the width of the receiving channel 31 , ie the distance of the gutter outer wall 33 from the gutter inner wall 34 in the transverse direction Q.

The main body 25 has within its first part 29 following the gravel track section 11 one in height direction H projecting casserole 48 , The casserole 48 has two in the transverse direction Q spaced apart each a first rail portion 16a facing leading edge 49 , The casserole 48 is inside 37 between the first two rail sections 16a arranged. The width of the casserole projection 48 in the transverse direction Q takes to the gravel track section 11 down. In a plan view in the height direction H has the casserole 48 For example, a wedge-shaped shape.

The casserole 48 serves to push or guide a no longer guided in the rails axle of a rail vehicle back in the direction of the rails. An indoor area 37 between the rails 16 running wheel gets to one of the casserole edges 49 of the casserole 48 in contact and is through the opposite of the track direction S oblique course of the respective leading edge back towards the respective rail 16 guided.

The main body 25 has at the gravel track section 11 associated end an end face 50 , At the front 50 is inside 37 between the rails 16 an inclined surface 51 available. In the embodiment, the inclined surface extends 51 in the transverse direction Q completely between the two female addicts 31 , The inclined surface 51 runs in rail direction S viewed from the gravel track section 11 inclined upwards at an angle to the direction of the rail S and diagonally to the height direction H , The inclined surface 51 forms in the embodiment, an end face of the casserole projection 48 , Due to the inclination of the inclined surface 51 can damage by hanging parts, such as parts of a coupling of a rail vehicle, on the track transition unit 10 and in particular on the body 25 be avoided or minimized. If the front side were perpendicular to the track direction S aligned, would depend on a rail vehicle hanging part with great force on the face. Due to the inclined inclined surface 51 the impact is reduced in the direction of travel of the rail vehicle and a drooping part can along the inclined surface 51 sliding to the top 28 of the basic body 25 be guided. This allows damage to the body 25 at least reduce it.

As it is in particular in 1 can be seen, the body indicates 25 at its front 50 outside the interior 37 following a respective receiving channel 31 one more outer sloping surface each 52 on, with the outer bevels 52 also from the gravel track section 11 walk diagonally upwards. The outer oblique surfaces are preferred 52 and the inclined surface 51 aligned parallel to each other and may preferably extend in the same plane.

The first part 29 of the basic body 25 is, for example, on his the gravel track section 11 facing side through the front side 50 and at in the rail direction S opposite end by a transverse channel 53 limited. The cross gutter 53 intersperses the main body 25 in the transverse direction Q complete and has a transverse gutter floor 54 in the height direction H below the rails 16 is arranged ( 3 ). The rails 16 span the cross gutter 53 For example, self-supporting and not supported on the transverse gutter floor 54 from. The cross gutter 53 can for example serve for drainage and drain water laterally to the outside. As it is in the 1 to 3 illustrated has the cross gutter 53 to the gravel track section 11 a much greater distance than the ballastless track section 12 , When the cross gutter 53 for draining the ballastless track section 12 is set up, it is advantageous to the cross gutter 53 close to the ballastless track section 12 to arrange. The cross gutter 53 can also directly the the ballastless track section 12 associated end of the body 25 form.

The cross gutter 53 Alternatively, it can also serve as installation space for other components, for example for laying cables or pipes.

Indoor 37 between the two rails 16 is the transverse channel 53 at least partially or completely covered. For covering serves in the embodiment, a grid 55 , The grate 55 extends in the embodiment at the level of the top 28 the adjacent areas of the body 25 and in the embodiment at the level of the top of the casserole 48 , Through the cover or the grate 55 This avoids having a drooping part of a rail vehicle in the cross channel 53 falls inside or attacks, resulting in damage to the rail vehicle or on the body 25 can lead.

Alternatively or in addition to the cover, the transverse gutter 53 be filled with a water-permeable bed, such as gravel or the like, at least partially. This also allows the cross gutter 53 still be used for drainage and at the same time is the intrusion of drooping parts of rail vehicles in the transverse channel 53 avoided. Also, the combination of a bed and the cover of the same area or different areas of the transverse gutter 53 is possible.

As it is for example in 3 can be seen, the main body may have one or more grounding terminals 56 to connect grounding cable. The grounding cables can be connected with a rail 16 or a ground terminal of the support body 14 get connected.

In 5 is another embodiment of a track transition unit 10 illustrated. The track crossing unit 10 is essentially as designed as previously related to the 1-4 described track body transition unit 10 so that reference may be made to the above description. In contrast to the previously described embodiment, the main body 25 the track body transition unit 10 a first transverse channel 53a and one in the direction of track S at a distance from the first transverse channel 53a arranged second transverse channel 53b on. The second cross channel 53b is at the body 25 Immediately following the ballastless track section 12 arranged associated with the end. About the second cross channel 53b especially the ballastless track section 12 be drained. Dash-dot is in 5 schematized indicated that the second transverse channel 53b analogous to the first cross channel 53a can be covered with a cover, for example, with another grating 55 , Alternatively, as described above, instead of the grate 55 or the cover also a bed of material in the respective transverse channel 53a . 53b be introduced.

Between the two transverse channels 53a . 53b has the track transition unit 10 one on the main body 25 arranged second rail holding device 60 , By means of the second rail holding device 60 is in each case a second rail section 16b of each rail 16 at the base body 25 stored. The second rail holding device 60 may be different from the first rail holder 30 be educated. The second rail holding device 60 is on a second part 61 of the basic body 25 Located on the ballastless track section 12 adjacent or adjacent to it is arranged. In the embodiment, the first part 29 and the second part 61 of the main body 25 through the first transverse channel 53a separated from each other. Alternatively, the first part could be 29 and the second part 61 in track direction S also connect directly to each other.

The second rail holding device 60 is particularly adapted to length changes of the rails 16 in the area of the ballastless track section 12 and / or displacements of the rails 16 in the height direction H and / or dynamic deformations of the rails 16 in the ballastless track section 12 to compensate. For example, the second rail holding device 60 a guide of the second rail section 16b in the rail running direction S and / or in the height direction H provide and support movements of the second rail portions 16b in other degrees of freedom, in particular movements in the transverse direction Q ,

Alternatively to the in 5 In the embodiment shown, it is also possible that the track body transition unit 10 in addition to a basic body 25 at least one additional additional basic body 62 having. The at least one additional basic body 62 is between the main body 25 and the ballastless track section 12 arranged. According to the embodiment 6 corresponds to the basic body 25 the embodiment according to the 1 to 4 , According to the example, the track body transition unit 10 according to the embodiment according to 6 only one additional basic body 62 on, the one connector body 63 forms. The connection body 63 is arranged in the direction of track S immediately adjacent to the ballastless track section 12. On his in track direction S opposite side closes example of the main body 25 at.

The connection body 63 has the first transverse channel in the embodiment 53a and the second cross channel 53b on, as described above in connection with the main body 25 according to 5 were explained. In addition, at the portion of the connection body 63 between the two transverse channels 53a . 53b the second rail holding device 60 for holding the second rail portion 16b, as discussed above 5 was explained. The transverse channels 53a . 53b can each have a grid 55 or another cover be covered and / or at least partially filled with a bed. The covered and / or filled areas are in 6 bordered by dash-dotted lines. As it is in 6 can be seen, the additional basic body 62 or connection body 63 indoor 37 between the rails 16 a longitudinal recess 64 have, which can also be covered or filled by a cover and / or bed.

In 7 is another embodiment of the track transition unit 10 illustrated. In contrast to the embodiment according to 11 has the track transition unit 10 one as a connection body 63 trained additional basic body 62 following the ballastless track section 12 , a basic body 25 following the gravel track section 11 and in between one or more additional additional basic body 62 on. The additional basic body 62 between the connector body 63 and the body 25 is preferably without transverse channel 53 executed. The additional basic body 62 including the connection body 63 have analogous to the main body 25 each a receiving channel 31 on, in a there extending rail section of the respective rail 16 is stored or held. The storage can be analogous to the first rail holding device 30 be educated. In a modification to this, the rail sections of the respective rails 16 in the additional body 62 also immovable firmly with the receiving channel 31 be connected. It is also possible on the additional basic bodies 62 to provide a third rail holding device extending from the first rail holding device 30 and / or the second rail holding device 60 different. However, it is preferred that the rail holding device on the additional basic bodies 62 identical structure, as the first rail holder 30, wherein optionally the plain bearing body 42 with the receptacle 31 can be glued or analogous to the first rail holder 30 guided movable in the receiving channel 31 is stored.

As in the embodiment according to 6 is also according to the embodiment 7 the second rail holding device 60 unlike the one in 5 embodiment shown not on the main body 25 but on one as a connection body 63 trained additional basic body 62 available. The connection body 63 is in the embodiment according to 7 according to the connection body 63 according to 6 so that reference may be made to the above description.

The track crossing unit 10 can thus be constructed modular. The number of additional basic body 62 can be varied as desired. At each track transition unit 10 is exactly one body 25 with a first rail holding device 30 available. The adjacent to the ballastless track section 12 existing second rail holding device 60 can either be in a second part 61 at the base body 25 or alternatively on a connection body 63 trained additional basic body 62 to be available. Both the main body 25 as well as the connection body 63 and / or one or more additional basic body 62 can each have one or more transverse grooves 53 , 53a, 53b. At least indoors 37 all transverse grooves are preferably covered and / or filled.

This adjustability is in 9 schematically illustrated by the dashed double arrows.

In the embodiment shown here, a varying distance between the rail of the first rail section 16a and the top 28 of the basic body 25 by the number and / or the thickness of slices 66 adjusted or balanced, as on the top 28 of the basic body 25 under the rail foot in the first rail section 16a to be ordered. The disks 66 are preferably by a screw on the body 25 attached and at the same time can be with the screw a clamping means the rail foot against the disc 66 Press and thus on the body 25 Fasten. Should the gravel track section 11 be repaired and in particular the ballast bed 18 can be stuffed, the fastenings or screwing the rail fasteners 65 the first rail holding device 30 be solved. After plugging the ballast bed 18 becomes the distance between the main body 25 and the rail foot by selecting a suitable thickness or a suitable number of discs 66 compensated for each rail attachment 65 and the attachment or screwing to the body 25 restored.

The invention relates to a track transition unit 10 with a basic body 25 and optionally additional, attached to the main body 25 subsequent additional basic bodies 62 , The track crossing unit 10 is in the rail running direction of at least two rails 16 between a gravel track section 11 and a ballastless track section 12 arranged to form a transition section. The main body 25 is on a surface 19 the track body arranged and has at its top 28 a first rail holding device 30 on, in each case a first rail section 16a the existing rails 16 is held such that a rail level change in the height direction H or vertical direction is enabled. Preferably, the first rail holding device forms 30 to a sliding bearing, for example by means of an upwardly open receiving channel 31 and one in the receptacle 31 supporting bearing body 42 that with the first rail section 16a the respective rail 16 connected is.
