Abstract (en)
A railway sleeper (1) has an under surface that is curved in order to enable the sleeper to be positioned in a tunnel so that a major part of the under surface and preferably substantially the entire under surface is in contact with the tunnel wall. The sleeper is preferably formed from sheet metal and has a central part formed from a single strip of sheet metal that is curved to lie flat on the tunnel wall. The sleeper may include a pair of baseplates (4,5) for supporting rails of the railway track, which are also formed from sheet metal, and a rib (10) formed in the sheet metal of the sleeper and located under each baseplate for supporting part of the load from the rail.
