Definitions

  • the present invention generally relates to railway tracks.
  • Railway tracks are the structures that support and guide trains or other rail- guided transportation vehicles.
  • the tracks typically include an earthen formation, a ballast in the form of aggregate lying upon the formation, parallel sleepers aligned in a row resting upon the ballast and a pair of railway rails resting upon the sleepers.
  • railway tracks are generally designed and constructed for extended life, high speeds and dynamic loading. There is a need for quick and low cost construction of track that is not subjected to high speed, high wear and high loading such as sidings and yards.
  • Rolling stock currently requires the use of a break in the rail such as a turnout to go from one line to another. It would be desirable to create the turnout anywhere on the network on a temporary basis for maintenance rolling stock and emergency situations.
  • Embodiments of the present invention provide a means for more quickly opening the line to rail traffic.

  • Each panel may include a pair of rail slots for receiving respective rails.
  • Each panel may include polymer for mounting the rails in the slots.
  • the rail slots may be located between the drainage or connection channels.
  • Each panel may include end engagement formations to facilitate end-to-end serial engagement of adjacent panels.
  • each rail slots may receive a tubular resilient filler to fill space between the rail and the panel.
  • Each support may include multiple panels, the module including an axially extending compression rod arrangement for compressing the panels together.
  • At least one support may define an opening between a pair of rails in which a rail worker can be located to perform maintenance to the underside of a wagon on the rails.
  • the module may further include at least one walkway for releasably fastening to said supports.
  • the walkway may define a drainage channel and a connection channel.
  • the walkway may include a panel which tapers towards the drainage channel.
  • the module may further include a fence for releasably fastening to the walkway.
  • a transporter for transporting at least one said module, the transporter including a container.

  • a method for diverting a railway track including the steps of:
  • the foregoing method may be used to quickly form a temporary alternative route for other trains on the same line to bypass the wreckage and damaged portion of the track.
  • the alternative route may be operational within hours (compared with days to re-open the track).
  • the method may further include the step of bending some of the modules.
  • the method may further include the step of connecting each end of the interconnected modules to the railway track.
  • a modular railway track including at least one of the portable railway track modules.
  • the modules may include one or more serially interconnected maintenance modules, temporary modules, transition modules or temporary turning modules.
  • Each maintenance module may provide a walkway or similar extended storage or work area to facilitate maintenance and washing of wagons.
  • Each temporary module may be straight.
  • Each transition module may be bowed or curved .
  • Each transition module may have curvilinear parallel rails.
  • the temporary turning modules may enable seamless connection to a mainline railway track.
  • the temporary turning modules may overlap with the railway track and include complementarily fitting pieces.
  • a track siding or walkway may be attached to any of the modules that facilitates drainage or liquid capture.
  • the siding may support structures including fencing, barriers, stairs or scaffolding.
  • Figure 1 a is a side sectional view of a portable railway track module in accordance with an embodiment of the present invention
  • Figure 1 b is a partial perspective view of the railway track module of Figure 1 a;
  • Figure 2 is a schematic plan view of a railway track showing both a train derailment and a temporary diversion track including portable railway track modules of Figure 1 ;

  • a portable railway track module 4 as shown in Figure 1 .
  • the railway track module 4 includes a pair of embedded railway rails 6a, 6b and an number of composite supports 2 for supporting the rails 6a, 6b (see also Figure 2).
  • the composite supports 2 are lighter (yet less durable) than traditional sleepers to facilitate portability of the module 4.
  • the track module 4 can be used to temporarily transport trains at lower speeds when, for example, forming a temporary diversion track around a train derailment as shown in Figure 2. After use, the used track modules 4 are typically disposed of or discarded.
  • the track module 4 includes rail levelers 8 for locating beneath the supports 2.
  • Each leveler 8 includes a tillable container in the form of a bag that can be filled with a settable slurry filler to level the railway rails 6a, 6b and stabilise the modules 4 during installation.
  • Each support 2 defines a pair of recesses 10a, 10b on its underside for receiving respective levelers 8.
  • Each support 2 also defines a central aperture 1 2 for receiving a anchoring ground screw (not shown).
  • Each support 2 is formed from lightweight composite material of high compressive strength.
  • the composite material includes polymeric and either concrete or cementitious material.
  • the rails 6a, 6b are fixedly embedded in the supports 2 as can best be seen in Figure 1 a and are received in recesses in the roofs of the supports 2.
  • Each support 2 includes internal reinforcing 14 encapsulated within the composite material.
  • Each rail 6 is typically formed from a number of serially interconnected rail segments (e.g. one segment per support), although may be integrally formed from a single piece of steel.
  • the diversion method involves serially arranging a number of the portable railway track modules 4a, 4b, etc. extending from the railway track 50. Some of the track modules 4 can be bent to form a radius as required. The track modules 4 can be interconnected together, and both ends of the connected modules 4 can be connected to the railway track 50 on respective sides of the derailment. In this manner, a temporary alternative route is quickly formed for other trains on the same line to bypass the wreckage 52 and damaged portions of the track 50. The alternative route including the track modules 4 will be operational within hours (compared with days to re-open the track 50). Once the train wreckage 52 has been removed, the track modules 4 can be removed and the track 50 can be restored.
