PROTOTYPE: these wagons were very similar to the 1894 T1 design. 18 wagons to Dia. T12 were built In 1938, with Dean-Churchward brakes. The final 6 wagons of T13 built during 1942-44, had lever brakes. They were used to carry chaired sleepers (loaded lengthwise) from the depot at Hayes. Sometimes plain timbers for points were carried. During the 1960s, the use of pre-assembled track panels made these wagons redundant. They were fitted with wooden sides and floors and used to carry concrete products from the works at Taunton, as their low floor made them easy to unload. Two of these remained in use on the Southern Region until at least the mid 1980s. DW100682 was air-piped and coded ZRW (Stores vehicle-concrete products). A number of these wagons are preserved e.g. West Somerset & Bluebell Railways.
