Definitions

  • the present invention relates to railway lines and in particular switches which are used at rail turnouts and crossings to direct railway traffic.
  • turnout shall be taken to include right hand and left hand turnouts, symmetrical turnouts, tandem turnouts, free-throw turnouts, left hand or right hand tandem turnouts, similar flexure turnouts and the like, and the term “crossing” shall be taken to include all forms of junction and cross-overs.
  • a switch blade is used which is moved towards or way from a rail in order that the railway traffic may move over the switch blade and the railway line connected thereto or over the rail associated with the switch blade.
  • Construction of such switch blades requires the tapering of the end of the switch blade and the fabrication of the switch blade from a steel having the strength characteristics to withstand the load carried by the switch blade.
  • the end of the switch blade being damaged, there is an increased possibility of a derailment and in order to prevent damage to a switch blade, it becomes necessary for railway traffic when approaching a switch to slow down in order not to place any excessive loads upon the mechanism of the turnout including the switch blade.
  • the present invention provides a turnout or crossing which can be negotiated by rail traffic with a reduced necessity for the traffic to slow down.
  • a rail switch for a rail turnout or crossing interposed at a junction between a set of rails, said switch comprising a stock rail pivotally mounted such that one free end at least is movable between at least two end positions wherein, at each end position, the stock rail is in line with a pair of opposed rails of said set of rails.
  • the embodiment of the present invention shown in Figures 1 to 3 is a dual stock rail crossing in which V- rail sections which are conventionally used in such crossings are removed and replaced by a switch 10.
  • the switch 10 is interposed at a junction between a set of rails comprising two pairs of rails 12 and 14, to provide alternative communication therebetween.
  • the switch 10 comprises two straight lengths of stock rail 16 held in spaced, parallel relation by a set of heel blocks 18 located at spaced intervals along the length of the rails 18.
  • the stock rails 16 are of full rail width and constant cross- section throughout their lengths.
  • the pairs of stock rails 16 are connected together by "Huck" bolts passed through the rails 16 and the heel blocks 18.
  • "Huck” bolts are in the nature of rivets.
  • pairs of adjacent rails 12 and 14 comprise insulated joints 20 which allow for expansion of the rails and electrically isolate the switch 10 from the remainder of the rail system.
  • the rail set comprises a main line 22 which has corresponding parallel rail portions in the pairs of rails 12 and 14 and a branch line 24 which also has corresponding parallel rail portions in the pairs of rails 12 and 14.
  • the rails 10, 12, 14, 22 and 24 are mounted on steel sleepers or the like 26. Further, the components of the switch 10 are mounted on chair plates 28. As can be seen in Figure 2, an electrically insulating layer 30 is located between each chair plate 28 and its associated sleeper 26.
  • each chair plate 28 is provided with a low friction, U.V. resistant bearing pad 32 of the type described and claimed in Australian Patent No. 534716.
  • the bearing pads 32 are each of a width so as to provide a support for the stock rails 16 in all of their positions..
  • a wing bracket 34 adjacent each end of each bearing pad 32 there is provided a wing bracket 34.
  • the wing brackets 34 are so located to correspond with the extreme positions of the stock rails 16 so as to prevent spreading of the track defined by the stock rails 16, in use.
  • the pairs of rails 12 and 14 are directly interconnected on each side of the switch 10 by an anti-expansion rail 36.
  • the anti-expansion rails 36 are fixedly connected to the rail sets 12 and 14 and are mounted to the chair plates 28 by means of track clips 38.
  • the anti-expansion rails 36 resist expansion or contraction of the rails 12 and 14 between the joints 20 so as to reduce variations in the gaps between the stock rails 16 and the pairs of rails 12 and 14. Typically,
  • the switch 10 is pivotally supported adjacent one end of the stock rails 16 on a pivot mounting 40.
  • the pivot mounting 40 comprises, as can be seen in Figure 3, a base plate 42 having a central recess having mounted therein a correspondingly shaped pivoting table 44.
  • a bushing 46 formed of, for example, low friction plastics material or brass is interposed between the base plate 42 and the pivoting table 44 and an electrically insulating layer 48 is located between the base plate 42 and the sleepers 26.
  • the rails 16 are firmly attached to the pivoting table 44 such as by means of a plurality of set screws 50.
  • a conventional point operating machine 52 is located adjacent the end of the switch 10 remote from the pivot mounting 40.
  • the point operating machine 52 is connected to the rails 16 by an articulated linkage 54 of known type.
  • the stock rails 16 are moved by the point operating machine 52 through the articulated linkage 54, between a first extreme position shown in Figure 1 in which one of the stock rails 16 is aligned with the main lines of the sets of rails 12 and 14 and is parallel to the rail 22. In this position the switch 10 is set for main line operation.
  • the stock rails 16 are pivoted on the pivot mounting 40 by extending the linkage 54 by means of the machine 52 so that the other of the stock rails 16 is aligned with the branch lines of the sets of rails 12 and 14 and is parallel to the rail 24. In this position the switch 10 is set for branch line operation.
  • the arrangement shown in Figures 4 to 6 is a stock rail turn out comprising a pair of switches 10.
  • the pair of straight rails 16 is replaced in each case by a pair comprising one straight rail 60 and one curved rail 62.
  • the rail system comprises a pair of parallel main line rails 64 on each side of the switch 10 and a pair of parallel, branch line rails 66 on a side of the switch 10.
  • the apparatus comprises a point changing machine 66 comprising a rod 70 connected to both switches 10 and arranged for longitudinal movement to move the stock rails 60 and 62 between two extreme positions.
  • each curved stock rail 62 is aligned with a main line rail 64 and a branch line rail 66. In this position, the turnout is arranged to direct traffic from the main line to the branch line.
  • each straight stock rail 60 is aligned with two main line rails 64.
  • the turnout is arranged for traffic movement along the main line.
  • a single V-shaped rail section 70 comprising a pair of rails 72 and 74 converging together.
  • the rail 72 is aligned with a further rail 76 and is parallel to a rail 78 and forms a main line.
  • the rail 74 is aligned with a further rail 80, is parallel to a rail 82 and forms a branch line.
  • a single stock rail 84 is connected to a pivoting table 40 as described hereinabove, at one end.
  • the stock rail 84 is arranged to be pivoted as described in relation to Figures 1 to 3, between the position shown in Figure 7 in which it is arranged for branch line operation and a further position in which it is arranged for main line operation.
  • the position of the switches of the present invention at either of their extreme positions may be signalled by a sensor means located at appropriate positions corresponding to the positions adjacent the free end of the switches. Further, an electromagnet may be provided adjacent the free end of each switch at each extreme position thereof. The electromagnet would be arranged to be activated on activation of the sensor means to hold the stock rail in position.
  • a turnout or crossing is provided whereby a pathway is defined through the turnout or crossing which does not require the use of any specialised forgings to support the load of any rail vehicle passing through the turnout or crossing and which may be subject to damage and as a result cause derailment.
  • Turnouts or crossings in accordance with the present invention avoid discontinuities in the running surface which is a major problem especially with conventional turnouts.
  • the switch can be used with double flanged wheels.
  • the switches of the present invention are suitable for use in conditions where there is a problem with snow since the snow does not become compacted between parts which are moved together as in conventional turnouts. Also, the use of the pads 32 reduces the tendency of the stock rail to become frozen to the base plate.
  • crossings of the present invention can be operated without guide rails which are required in conventional crossings, and the wing brackets 34 help prevent lateral forces pushing the stocks outwardly as is normally the case with conventional crossings.
  • each stock rail only takes the load from one line which is either the main line or the branch line, so that the stock rails tend to wear equally.
