Abstract: A prefabricated platform unit (1), for construction or refurbishment of a railway station platform, has a stepped upper surface (4) with a recessed planar forward portion (4a) on which edge copers (23) are to be mounted. 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). Construction of a new platform may include the steps of constructing foundations alongside the railway, constructing upstanding supporting members on the foundations, and mounting a superstructure including the prefabricated platform units on the supporting members.

Abstract: A railway station platform structure is constructed by: (a) constructing foundations (36) alongside the railway: (b) constructing up-standing supporting members (37) on the foundations (36); (c) mounting cross beams (38) on the supporting members (37) so that the cross beams have cantilevered extending beyond the supporting members (37) towards the railways, (d) mounting longitudinal beams (42) on the cross beams (38); and (e) mounting platform units (1) on the longitudinal beams (42) 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 portion of the cross beams (38).
