Description
The present invention relates to a continuous action mobile machine ~or tamping ballast under successive ties fastened to rails of a railroad track. The ballast tamping machine comprises a first machine frame, two spaced undercarriages supporting the first machine frame on the track for mobility in an operating direction, the first machine frame having a forward end and a rear end in the operating direction, a tool carrier arranged between the two undercarriages and vertically adjustably supporting a track lifting and lining unit and at least one tamping unit including pairs of reciprocable and vibratory tamping tools immersible in the ballast, a longitudinal displacement drive connecting the tool carrier to the first machine frame, a second machine frame, at least one undercarriage supporting ; the second machine frame on the track, a ballast plow ~` arrangement vertically adjustably mounted on the second machine frame between two undercarriages, and power drives for operating the ballast plow arrangement.
German patent application No. 3,819,717, published March 23, 1989, discloses a continuous action track leveling, lining and tamping machine of this type, with two successive machine frames supported on undercarriages being coupled to the rear end of the machine frame of the machine ~he centrally arranged machine ~rame, which is coupled directly to the rear end~ carries a vertically adjustable plow arrangement between two undercarriages, and the trailing machine frame carries a track stabilization unit between two undercarriages and a broom arrangement. Furthermore, a cantilevered forward end of the machine frame of the track leveling, lining and tamping machine carries a vertically ~1~
adjustable and transversely pivotal small ballas~ plow associated with each track rail. A respective driver's cab is mounted at each end of this machine frame and an operator's cab is mounted thereon within view of the tamping unit. This machine enables the ties to be cyclically tamped while the machine advances continuously and, at the same time r the ballast bed may be suitably shaped and the leveled and lined track may be stabilized with the trailing track stabilization unit. ~n a modified embodiment, the third ` 10 machine frame carrying the track stabilization unit is omitted and only one additional machine frame carrying plow and broom arrangements trails the machine frame of the track ; levelingt lining and tamping machine. When the ballast is very irregularly distributed or if there is too little ballast available for proper tie tamping, it is necessary to precede the same by a ballast plow which suitably shapes the ballast bed and thus prepares it for the tie tamping operation. Both disclosed embodiments provide driver's cabs at both ends of the machine frame of the track leveling, lining and tamping machine and all the machine frames reach up to the level of the driver's cabs.
U. S. patent No. 4,165,694, dated August 28, 1979, discloses an intermittently advancing track leveling, lining and tamping machine for the cycllc tamping of track ties, a respective trailer supported on a single undercarriage being linked respectively to the forward and rear end of the `I
machine frame of the intermittently advancing track leveling~ lining and tamping machine. A telescoping coupling longitudinally displaceably connects the front trailer to this machine frame, and the front ~railer carries : , ~
d,3 ~
a vertically adjustable plow arrangement. An operator's cab is mounted on the trailer above the plow arrangement and the machine frame of this trailer has the same height as that of the track leveling, lining and tamping machine. The rear trailer carries a vertically adjustable broom arrangement and track sensing elements for the reference system of the machine. This machine arrangement has not been built for commercial use.
A similar machine arrangement has been disclosed in U.
S. patent No~ 4,165,693, dated August 28, 1979, but the front trailer carrying the plow arrangement is replaced by an independently continuously advancing, self7propelled vehicle with its own cab, operating controls and indicator for surveying the corrected track position.
It is the primary object of this invention to provide a continuous action mobile machine of the firstdescribed type for tamping ballast under successive t~es fastened to rails of a railroad track, which improves the economics and efficiency of tie tamping and working o~ the ballast bed as well as the usefulness of the machine under varying operating conditions.
The above and other objects and advantages are accomplished according to the invention with a coupling linking the second machine frame to the forward end of the first machine frame, the second machine frame preceding the first machine frame in the opera~ing direction.
This machine arrangement for the first time makes it possible continuously to shape the ballast bed and immediately thereafter to tamp the ties with a continuously advancing ballast tamping machine in a single operating o3o r~
stage while ~he machine frames move non~stop along the track and the plow arrangement distributes the ballast for uniform tamping under the successive ties. It enables proper ballast distribution and the resultant uniform tie tamping to be effected economically with a small operating crew and a relatively simple machine in a single pass. Furthermore, since the machine frame carrying the ballast plow arrangement is linked directly to ~he machine frame carrying the tamping unit, the plow arrangement may be operated directly from a cab on the latter machine frame and the former machine frame may be pushed along the track by the driven machine frame trailing it under sufficient power to enable the ballast to be continuously distributed without any problems by the plow arrangement. This combination of the two linked machine frames and the driving power transmission made possible thereby also makes it possible to make the second machine frame supporting the plow arrangement substantially flat and low. This has the added advantage that the cab at the forward end of the first machine frame provides a clear view of the track in front of the machine as well as enabling an operator in the cab to observe and operate the plow arrangement so that it may be constantly adjusted to prevailing ballast conditions. In addition, the transmission of high pulling and pushing forces between the two linked machine frames makes it possible to incorporate the machine without problems in a train for moving the machine to another operating site.
The above and other objects, advantages and features of the present invention will become more apparent from the following detailed description of certain now preferred ~4= >
embodiments thereof, taken in conjunction with the accompanying, somewhat schematic drawing wherein FIG. 1 is a side elevational view of one embodiment of a continuous action mobile machine for ~amping ballast under successive ties fas~ened to rails of a railroad track;
FIG~ 2 is a ~op view of the machine of FIG. l;
FIGS. 3 to 5 show diagrammatic side elevations of a continuous action track leveling, lining and tamping machine of ~he same type as shown in FIGS. 1 and 2 but having buffer couplings at the forward and rear ends of its machine frame, with the second and third machine frames linked thereto in different combinations, an unobs~ructed view at the track ahead and rearwardly of the first machine frame being afforded in all combinations, FIG. 3 showing the same combination of the three machine frames as FIG. 1, FIG. 4 showing the use of the track leveling, lining and tamping machine with a trailing arrangemen~ of the second machine frame carrying the plow arrangement~ as indicated in chain~do~ted lines, and FIG. 5 showing this combina~ion with a fourth machine frame carrying a track stabilization unit;
and , , ; FIG. 6 illustrates a continuous action mobile track ~;~ leveling, lining and tamping machine with a leading machine ~: frame carrying a vertically adjustable plow arrangement, ~:~ also in a diagrammatic side elevation.
Referring now to the drawing and first to FIGS~ 1 and 2, there is shown continuous action mobile machine 1 for tamping ballast under successive ties ~ fastened to rails 5 of railroad track 6. The illus~rated track leveling, lining and tamping machine comprises first machine frame 11 and two 5~
~-- :
~ ' .
~ t~ 2 spaced undercarriages 2 supporting the first machine frame on the track for mobility in an operating direction under the power of drive 3~ First machine frame 11 has forward end 27 and rear end 36 in the operating direction indicated by arrow 15. In addition to propelling drive 3, first machine frame 11 also carries operator's cab 9 with central control panel 10 as well as operator's cabs 7 and 8 at the forward and rear ends of machine frame 11. Conventional leveling and lining reference system 12 is also mounted on the first machine frame to indicate the track position.
Furthermore, the first machine frame supports central power plant 13. Tool carrier 14 is arranged between the two widely spaced undercarriages 2, 2 and vertically adjustably supports track lifting and lining unit 23 and at least one tamping unit 19 including pairs of reciprocable and vibratory tamping tools 20 immersible in the ballastO
Longitudinal displacement drive 18 connects tool carrier 14 to first machine ~rame 11 for displacing the tool carrier relative to the first machine frame during the non~stop advance of the machine frame~ The rear end of tool carrier 14 is supported and guided on track 6 by undercarriage 16 while its front end is longitudinally displaceably mounted on guide bracket 17 affixed to first machine frame 11.
Lifting and lining drives 21, 22 link unit 23 to tool carrier 14 and two flanged rollers are spaced along each track rail 5 to support the track lifting and lining unit on the track and to function as lining tools. In addition, flanged lifting rollers 24 and lifting hooks 25 are mounted on unit 23 or engagement with each rail to function as lifting tools. The operation of the lifting and lining 6~
: ' .
drives is under the control of reference system 12 to correct position errors in the track. In addition to drive 18, tool carrier 14 is propelled by drive 26 ac~ing on the wheels of undercarriage 16~
Second machine frame 29 of vehicle 30 is supported on track 6 by single undercarriage 2~ and ballast plow arrangement 32 is vertically adjustably mounted on the second machine frame between two undercarriages, i.e forward undercarriage 2 of first machine frarne 11 and single undercariage 28. The illustrated ballast plow arrangement is generally conventional and comprises central plow 34 and shoulder plows 35 operated, respectively, by power drives 31 and 33. According to the present invention, a coupling links second machine frame 29 to forward end ~7 of first machine frame 11 and the second machine frame precedes the first machine frame in the operating direction.
As shown in the drawing, the illustrated embodiment further comprises third machine frame 38 of vehicle 39 supported on track 6 by single undercarriage 37. sroom arrangement 43 is vertically adjustably mounted on the ~hird machine frame, and power drive 40 vertically adjusts the .
broom arrangement on the third machine frame~ Another coupling links the third machine frame to rear end 36 of first machine frame 11 and the third machine frame trails the first machine frame in the operating direction. In the preferred illustrated embodiment, the continuous action mobile ballast tamping machine further comprises transversely extending conveyor band 42 associated with the broom arrangement and driven by drive 41.
This preferred arrangement of a leading and trailing .
~, vehicle respectively deslgned to shape the ballast bed and to sweep ballast into the cribs makes it possible to bring sufficient hallast for the tie tamping operation to the tamping sites immediately before tamping and to provide a finished track immediately thereafter whereby a uniform compacting of the ballast under the ties is assured and a longlasting corrected track position is obtained without the usual use of separate ballast plows before and/or after the tie tamping operation.
As shown, second and third machine frames 29 and 38 are trailers supported on track 6 by a single undercarriage 28 and 37, the plow and broom arrangements 32 and 43 being mounted, respectively, between the single undercarriage and a respective one of undercarriages 2, 2 supporting first machine frame 11 on the track. These simple trailers carrying the plow and broom arrangements enable power to be effectively transmitted from self-propelled track leveling, lining and tamping machine 1 so that these trailers are pushed and pulled under sufficient force to enable the ballast plow and sweeping arrangements to function properly, In addition~ existing track leveling, lining and tamping machines may be readily retrofitted by coupling the ; trailers to their forward and rear ends.
The two widely spaced undercarriages 2, 2 support first ; machine frame 11 on track 6 adjacent forward and rear ends 27, 36 thereof, and the second and third machine frames comprise substantially centered carriers 45, 46 projecting therefrom towards the forward and rear ends, respectively, and the couplings are universal pivots 47, 48 connecting second and third machine frames 29, 38 ~o respective ends o8o :
27, 36 of the first machine frame adjacent the spaced undercarriages. ~his type of coupling is simple and robust, assuring proper movement of the second and third machine frames on the track rails even in sharp curves while ; dependably transmitting the propelling power from the track leveling, lining and tamping machine to the ballast plow arrangement and the broom arrangement sweeping excess ballast into the cribs. Each vehicle 30, 39 has buffer couplings 49, 53 at the ends thereof opposite to universal pivots 47, 48.
Respective operator's cab 7 r 8 mounted on forward and rear ends 27, 36 of ~irst machine frame 11 within view of the plow and broom arrangements 32 and 43, respectively, (see viewing field indicated in broken lines) provide control points 44 for operation of the plow and broom arrangements so that the second and third machine frames need to carry no operator's cabs, these machine frames extending in a plane just above undercarriages 28, 37 supporting the same on the track. This construction provides very simple vehicles ~or support of the plow and broom arrangements, the lowslung machine frames of the vehicles giving the operators in the cabs on the track leveling, lining and tamping machines an unobstructed view o~ the track so that they may readily operate and control the ballast plow and broom.
In operation, track leveling, lining and tamping machine l, together with trail~r vehicles 30, 39, advances continuously in the operating direction indicated by arrow 15 while tool carrier 14 with tamping units l9 and track lifting and lining unit 23 intermittently advances e~9o intermittently from tie to tie. The drives of center plow 32 and/or shoulder plows 35 of ballast plow arrangement 32 may be readily operated from control point 44 in cab 7 because the operator can clearly observe the ballast conditions. This is very important Eor the expeditious and continuous advance of the machine during the tamping operation because ballast conditions often change suddenly and a prompt repositioning of the ballast plows may then be needed to assure a continuous and uniform flow ~f ballast to 10 the tamping sites a'c which tamping tools 20 tamp ballast under ties 4. In the same manner, it is easy to control the finishing operation by broom arrangement 43 from control point ~L4 in cab 8.
FIG. 3 illustrates generally similar continuous action track leveling, lining and tamping machine 51 wherein track lifting and lining unit 57 precedes tamping unit 56 in the operating direction indicated by arrow 60, first machine frame 54 constituting a standard railroad vehicle having buffer couplings 58, 59 at ~he forward and rear ends o~ the 20 first machine frame, and second and third machine frames 61 and 66 having buffex couplings 71r 72 at opposite ends ~ thereof for readily detachable linking to each other and to ; a selected end of the first machine Erame, respectively.
The opposite ends of first machine frame 54 are supported by undercarriages 52~ 52 on track 53. Longitudinally displaceable tool carrier 55 carries tamping unit 56 and track lifting and lining unit 57. Machine frame 61 of trailer vehicle 63 is supported on the track by single undercarriage 62 and carries vertically adjustable ballast 30 plow arrangement 64 comprised of central and shoulder plows ,, .
, ~, '~10~
65. Machine frame 66 of trailer vehicle 70 is also supported on the track by a single undercarriage 67 and carries vertically adjustable broom arrangement 68 equipped with transverse conveyor band 69. The trailer vehicles are linked by the buffer couplings 71, 72 to buffer couplings 58, 59 of first machine frame 54, the operation of the machine being the same as that of FIGS. 1 and 2, The buffer couplings at the ends of the machine frames enable the three machine frames to be readily coupled together and detached from each other while all three vehicles can be incorporated into a train of standard railroad cars for quick and secure movement to another operating site.
FIGS. 4 and 5 diagramma~ically show different possibilities for the use of continuous action track leveling, lining and tamping machine 51 with trailer vehicles 63 and 70. AS shown in FIG. 4, ballast plow vehicle 63 may be detached from forward coupling 58 of machine frame 54 and, as shown in chain~dotted lines~ may be coupled to rear coupling 59 thereof. In this case, ballast sweeping vehicle 70 is simply coupled to the rear end o:E
- vehicle 630 As shown in broken lines, plow arrrangement 64 as well as broom arrangement 63 may still be viewed from the rear cab on machine frame 54 and may, therefore, be operated from this control point in this arrangement, tooO This arrangement of the three machine frames may be used when sufficient ballast is available at the tamping sltes and no additional ballast flow thereto is required while it is desired to provide a predetermined shape to the ballast bed after tamping, with the finishing operation being provided by the broom.
~lle ~' In the arrangement of FIG. 5, track stabilizer 73 is incorporated in the machine combination of this invention.
As shown, the track stabilizer comprises a low~slung machine frame supported on the track by undercarriages 74 at the ends thereof and carrying two track stabilization units 75 therebetween. As conventional, each track stabilization unit is locked to the track rails by railengaging rollers to apply high vertical forces thereto while subjecting them to substantially horizontal vibrations. Leveling reference system 76 controls the extent to which these forces embed the track in the ballast bed~ End buffer couplings 77 enable track stablizer 73 to be linked to vehicle 70 and to the rear buffer coupling of either vehicle 63 or machine frame 54 of the track leveling, lining and tamping machine, depending on the prevailing ballast conditions.
FIG. 6 diagrammatically illustrates track leveling, lining and tamping machine 78 whose machine frame 79 is supported at its opposite ends by widely spaced undercarriages 80 for non~stop advance along track 81 in an operating direction indicated by arrow 82. I,ongitudinally displaceable tamping units 83 and track lifting and lining unit 84 are arranged between the undercarriages. Buffer couplings 85, 86 are provided at both ends of machine frame 79. Buffer coupling 86 at forwar~ end 87 of the machine frame is linked to buffer coupling 89 of vehicle 90 whose machine frame 93 also is equipped at both ends with buffer couplings 88, 89. Machine frame 93 is supported on track 81 by two spaced undercarriages 91, 91 wherebetween vertically adjustable plow arrangement 92 is mounted on the machine frame. A cantilevered forward end of machine frame 93 ~12~
carries vertically adjustable broom arrangement 94 comprising a rotatable ballast broom. The machine framè of vehicle 90 also is low and provides an unobst~uc~ed view of the plow and broom arrangements for an operator in driver's and opera~or's cab 95 at forward end 87 of machine frame 790 This simple combination of a flat ballast plow and broom suppor~ing vehicle with a continuous ac~ion ~rack leveling, lining and ~amping machine provides a very economical system for shaping the ballast bed and assuring a constant flow of sufficien~ ballast to the tie ~amping sites in a single pass during which the ~ies are tamped.

Second machine frame 29 of vehicle 30 is supported on track 6 by single undercarriage 2~ and ballast plow arrangement 32 is vertically adjustably mounted on the second machine frame between two undercarriages, i.e forward undercarriage 2 of first machine frarne 11 and single undercariage 28. The illustrated ballast plow arrangement is generally conventional and comprises central plow 34 and shoulder plows 35 operated, respectively, by power drives 31 and 33. According to the present invention, a coupling links second machine frame 29 to forward end ~7 of first machine frame 11 and the second machine frame precedes the first machine frame in the operating direction.
As shown in the drawing, the illustrated embodiment further comprises third machine frame 38 of vehicle 39 supported on track 6 by single undercarriage 37. sroom arrangement 43 is vertically adjustably mounted on the ~hird machine frame, and power drive 40 vertically adjusts the .
broom arrangement on the third machine frame~ Another coupling links the third machine frame to rear end 36 of first machine frame 11 and the third machine frame trails the first machine frame in the operating direction. In the preferred illustrated embodiment, the continuous action mobile ballast tamping machine further comprises transversely extending conveyor band 42 associated with the broom arrangement and driven by drive 41.
This preferred arrangement of a leading and trailing .
~, vehicle respectively deslgned to shape the ballast bed and to sweep ballast into the cribs makes it possible to bring sufficient hallast for the tie tamping operation to the tamping sites immediately before tamping and to provide a finished track immediately thereafter whereby a uniform compacting of the ballast under the ties is assured and a longlasting corrected track position is obtained without the usual use of separate ballast plows before and/or after the tie tamping operation.
As shown, second and third machine frames 29 and 38 are trailers supported on track 6 by a single undercarriage 28 and 37, the plow and broom arrangements 32 and 43 being mounted, respectively, between the single undercarriage and a respective one of undercarriages 2, 2 supporting first machine frame 11 on the track. These simple trailers carrying the plow and broom arrangements enable power to be effectively transmitted from self-propelled track leveling, lining and tamping machine 1 so that these trailers are pushed and pulled under sufficient force to enable the ballast plow and sweeping arrangements to function properly, In addition~ existing track leveling, lining and tamping machines may be readily retrofitted by coupling the ; trailers to their forward and rear ends.
The two widely spaced undercarriages 2, 2 support first ; machine frame 11 on track 6 adjacent forward and rear ends 27, 36 thereof, and the second and third machine frames comprise substantially centered carriers 45, 46 projecting therefrom towards the forward and rear ends, respectively, and the couplings are universal pivots 47, 48 connecting second and third machine frames 29, 38 ~o respective ends o8o :
27, 36 of the first machine frame adjacent the spaced undercarriages. ~his type of coupling is simple and robust, assuring proper movement of the second and third machine frames on the track rails even in sharp curves while ; dependably transmitting the propelling power from the track leveling, lining and tamping machine to the ballast plow arrangement and the broom arrangement sweeping excess ballast into the cribs. Each vehicle 30, 39 has buffer couplings 49, 53 at the ends thereof opposite to universal pivots 47, 48.
Respective operator's cab 7 r 8 mounted on forward and rear ends 27, 36 of ~irst machine frame 11 within view of the plow and broom arrangements 32 and 43, respectively, (see viewing field indicated in broken lines) provide control points 44 for operation of the plow and broom arrangements so that the second and third machine frames need to carry no operator's cabs, these machine frames extending in a plane just above undercarriages 28, 37 supporting the same on the track. This construction provides very simple vehicles ~or support of the plow and broom arrangements, the lowslung machine frames of the vehicles giving the operators in the cabs on the track leveling, lining and tamping machines an unobstructed view o~ the track so that they may readily operate and control the ballast plow and broom.
In operation, track leveling, lining and tamping machine l, together with trail~r vehicles 30, 39, advances continuously in the operating direction indicated by arrow 15 while tool carrier 14 with tamping units l9 and track lifting and lining unit 23 intermittently advances e~9o intermittently from tie to tie. The drives of center plow 32 and/or shoulder plows 35 of ballast plow arrangement 32 may be readily operated from control point 44 in cab 7 because the operator can clearly observe the ballast conditions. This is very important Eor the expeditious and continuous advance of the machine during the tamping operation because ballast conditions often change suddenly and a prompt repositioning of the ballast plows may then be needed to assure a continuous and uniform flow ~f ballast to 10 the tamping sites a'c which tamping tools 20 tamp ballast under ties 4. In the same manner, it is easy to control the finishing operation by broom arrangement 43 from control point ~L4 in cab 8.
FIG. 3 illustrates generally similar continuous action track leveling, lining and tamping machine 51 wherein track lifting and lining unit 57 precedes tamping unit 56 in the operating direction indicated by arrow 60, first machine frame 54 constituting a standard railroad vehicle having buffer couplings 58, 59 at ~he forward and rear ends o~ the 20 first machine frame, and second and third machine frames 61 and 66 having buffex couplings 71r 72 at opposite ends ~ thereof for readily detachable linking to each other and to ; a selected end of the first machine Erame, respectively.
The opposite ends of first machine frame 54 are supported by undercarriages 52~ 52 on track 53. Longitudinally displaceable tool carrier 55 carries tamping unit 56 and track lifting and lining unit 57. Machine frame 61 of trailer vehicle 63 is supported on the track by single undercarriage 62 and carries vertically adjustable ballast 30 plow arrangement 64 comprised of central and shoulder plows ,, .
, ~, '~10~
65. Machine frame 66 of trailer vehicle 70 is also supported on the track by a single undercarriage 67 and carries vertically adjustable broom arrangement 68 equipped with transverse conveyor band 69. The trailer vehicles are linked by the buffer couplings 71, 72 to buffer couplings 58, 59 of first machine frame 54, the operation of the machine being the same as that of FIGS. 1 and 2, The buffer couplings at the ends of the machine frames enable the three machine frames to be readily coupled together and detached from each other while all three vehicles can be incorporated into a train of standard railroad cars for quick and secure movement to another operating site.
FIGS. 4 and 5 diagramma~ically show different possibilities for the use of continuous action track leveling, lining and tamping machine 51 with trailer vehicles 63 and 70. AS shown in FIG. 4, ballast plow vehicle 63 may be detached from forward coupling 58 of machine frame 54 and, as shown in chain~dotted lines~ may be coupled to rear coupling 59 thereof. In this case, ballast sweeping vehicle 70 is simply coupled to the rear end o:E
- vehicle 630 As shown in broken lines, plow arrrangement 64 as well as broom arrangement 63 may still be viewed from the rear cab on machine frame 54 and may, therefore, be operated from this control point in this arrangement, tooO This arrangement of the three machine frames may be used when sufficient ballast is available at the tamping sltes and no additional ballast flow thereto is required while it is desired to provide a predetermined shape to the ballast bed after tamping, with the finishing operation being provided by the broom.
~lle ~' In the arrangement of FIG. 5, track stabilizer 73 is incorporated in the machine combination of this invention.
As shown, the track stabilizer comprises a low~slung machine frame supported on the track by undercarriages 74 at the ends thereof and carrying two track stabilization units 75 therebetween. As conventional, each track stabilization unit is locked to the track rails by railengaging rollers to apply high vertical forces thereto while subjecting them to substantially horizontal vibrations. Leveling reference system 76 controls the extent to which these forces embed the track in the ballast bed~ End buffer couplings 77 enable track stablizer 73 to be linked to vehicle 70 and to the rear buffer coupling of either vehicle 63 or machine frame 54 of the track leveling, lining and tamping machine, depending on the prevailing ballast conditions.
FIG. 6 diagrammatically illustrates track leveling, lining and tamping machine 78 whose machine frame 79 is supported at its opposite ends by widely spaced undercarriages 80 for non~stop advance along track 81 in an operating direction indicated by arrow 82. I,ongitudinally displaceable tamping units 83 and track lifting and lining unit 84 are arranged between the undercarriages. Buffer couplings 85, 86 are provided at both ends of machine frame 79. Buffer coupling 86 at forwar~ end 87 of the machine frame is linked to buffer coupling 89 of vehicle 90 whose machine frame 93 also is equipped at both ends with buffer couplings 88, 89. Machine frame 93 is supported on track 81 by two spaced undercarriages 91, 91 wherebetween vertically adjustable plow arrangement 92 is mounted on the machine frame. A cantilevered forward end of machine frame 93 ~12~
carries vertically adjustable broom arrangement 94 comprising a rotatable ballast broom. The machine framè of vehicle 90 also is low and provides an unobst~uc~ed view of the plow and broom arrangements for an operator in driver's and opera~or's cab 95 at forward end 87 of machine frame 790 This simple combination of a flat ballast plow and broom suppor~ing vehicle with a continuous ac~ion ~rack leveling, lining and ~amping machine provides a very economical system for shaping the ballast bed and assuring a constant flow of sufficien~ ballast to the tie ~amping sites in a single pass during which the ~ies are tamped.
