Mechanical Method Railway Track Construction. Figure 10 is an exploded isometric view of the second embodiment of the platform structure. A method of refurbishing a railway station platform, including the following steps: (a) excavating a region of the surface of the platform, the said region extending to the front edge of the platform ; (b) installing in the excavated region a unit according to any of claims 1 to 13; and (c) installing edge copers on the forward portion of the upper surface of the installed unit. I'm thinking of construction the edges that form the platform base from 6mm MDF, but have no idea how far back to set them from the track. ... Track Construction Machinery and Railway Tool Equipment. A platform structure as claimed in any of claims 29 to 41, in which the longitudinal beams are integral with the platform units. A unit as claimed in any preceding claim, the unit being in the form of a slab having a substantially planar bottom surface. In the forward portion there are several through-holes 11 (one hole may be sufficient) for supplying grout to the underside of the slab unit. Integral to station layout are its platforms, which are tied to passenger capacity and railway timetables. Our consultative approach is driven by understanding our customers’ objectives. Type 3: 10,000 – 30,000 incoming passengers/day (medium stations). Railway Track and Platform Drainage Systems. Network Rail copings are available in two industry-approved sizes 930 x 760 x 100 and 1219 x 914 x 100. 18. 43. iLECSYS in the UK have designed and constructed a new type of platform for Britain's railways using GRP composite from Fiberline. Prestressed Hollowcore Planks and Reinforcement Concrete Beams A method of refurbishing a railway station platform, substantially as described with reference to Figure 5 of the accompanying drawings. A platform structure as claimed in any of claims 29 to 38, in which the upper surfaces of the cross beams are substantially flush with the upper surfaces of the longitudinal beams. a dead-end or siding. (2) In the green zone the ground is prepared and excavated to provide two trenches parallel to the track. To assist installation, temporary lifting rings (not shown) can be fitted to anchorages (not shown) located in or near the plinth 27 and in the forward portion 4a of the upper surface of the slab unit. Refurbishment of an exiting platform may be performed by excavating a region 22 of the platform surface to the front edge, installing a prefabricated platform unit 1 in the excavated region, and installing edge copers 23. (8) Platform lighting is installed, a lighting column being inserted through the recess 33 in at least one of the slab units 1 and bolted to the cross beam 38 below. For a platform width of 4 metres, four longitudinal beams should be used. A platform structure as claimed in any of claims 29 to 46, in which the platform units include raised portions which are aligned to constitute a plinth to the rear of the platform structure. 22. The upper edges of the cross beams 38 have recesses 43 which accommodate end portions 42a of the beams 42 resting on resilient rubber pads 44 at the bottoms of the recesses 43. In first type of machine, the track material carried by the material. A platform substructure as claimed in any of claims 29 to 34, in which the cross beams are integral with the longitudinal beams. A platform structure as claimed in claim 32, in which the said formations on the supporting members comprise tie bars and the said formations on the cross beams comprise through-holes. A 100 lb double headed rail is shown in the figure. An island platform has through platforms on both sides; it may be indented on one or both ends, with bay platforms. Image orientation. Content type. Instead of fitting the edge copers and tactile paving elements on the slab units after the installation of the slab units, it may be possible to fit them on the slab units before the slab units are mounted on the supporting structure. A railway station platform structure comprising: foundations alongside the railway; upstanding supporting members rising from the foundations; cross beams mounted on … 31. Concrete is then poured into the trenches to form strip foundations The construction of platform extensions is restricted by the requirement to minimise disruption to normal use of the existing platform, to accommodate the works within existing train service patterns, and to have possession of the track while much of the construction work is carried out. One slab unit I has a recess 33 in one edge, for receiving a lighting column (not shown). Matrox Graphics. 1. A method as claimed in any of claims 13 to 22, in which, before step (a), the platform is cut to a given depth along lines delimiting a rear edge and side edges of the region to be excavated. The above described steps (1) - (6) are repeated until at least part of the length of the existing platform has been refurbished. Figure 1 is a plan view of a prefabricated platform unit or slab unit primarily for refurbishment of an existing platform; Figure 2 is a side elevation of the slab unit; Figure 3 is an enlarged fragmentary vertical section taken on line III-III in Figure 1 ; Figure 4 is an enlarged fragmentary vertical section taken on line IV-IV in Figure 1; Figure 5 is an exploded isometric view of an existing platform and a refurbished part of the platform; Figure 6 is an isometric view of three slab units, showing a preferred embodiment for use in the construction of a new platform structure; Figure 7 is a vertical section through a platform structure incorporating the slab units of Figure 6, in a first embodiment; Figure 8 is an exploded isometric view of the first embodiment of the platform structure; Figure 9 is a vertical section through a second embodiment of the platform structure; and A platform structure as claimed in any of claims 29 to 33, in which the cross beam are connected to the supporting members solely by mechanical connection devices. 3. The following process is then carried out. In the present example five edge copers 23 are mounted side by side across the two metre width of the slab unit. The passengers’ platform should be covered for a minimum distance of 60 to 61 m of their length. 48. A prefabricated unit for construction or refurbishment of a railway station platform. 29. Geographic location (sub-urban, city access, city centre). The awkward permanent way with Downpatrick railway station being on a branch necessitated the construction of the triangle and Loop platform. A method of constructing a railway station platform structure, including the following steps: (a) constructing foundations alongside the railway; (b) constructing upstanding supporting members on the foundations; (c) mounting cross beams on the supporting members so that the cross beams have cantilevered portions extending beyond the supporting members towards the railway; (d) mounting longitudinal beams on the cross beams; and (e) mounting platform units on the longitudinal beams so that side edge surfaces of the units extend away from the railway and front edge surfaces of the units extend along the railway beyond the ends of the cantilevered portions of the cross beams.
