Low floored GWR sleeper wagon, built in 1938. It is seen here in April 2003 as restored by Geoff Hackett's gang, and in use carrying sleepers. Richard Salmon
100677 is a Diagram T12 wagon designed by the Great Western Railway to carry wooden sleepers from their creosoting plant at Hayes, Middlesex to a work site. Built in 1938 at the GWR Swindon Works as part of a lot (No.1313) of eighteen vehicles, it has a carrying capacity of 18 Tons, is fitted with vacuum brakes and has a design tare weight of 11 Tons 16 cwt. It is fitted with a Dean/Churchward ratchet handbrake.
To assist in loading, the side stanchions are in two halves, designed to slot together. There are pockets for holding-down chains on each side of the wagon. In theory, 100677 is able to carry 160 sleepers fitted with chairs. Unlike most GWR wagons, this one has no code name.
These wagons joined an existing fleet of 101 similar, but slightly smaller wagons built to Diagram T1. The last diagram T1 wagon was completed in 1900 and the design was fitted with a handbrake only. A further six vacuum-braked wagons were built in 1942/3; these being similar to the diagram T12 vehicles, but fitted with a lever handbrake.
Most of the sleepers used prior to Nationalisation were cut from softwood. These had to be pressure-treated with creosote to prevent rot. The "timbers" used under pointwork were normally hardwood, which did not need to be pressure-treated.
The cast-iron chairs which were fitted to the sleepers were designed to fit the weight and profile of the rail used. For example, the LB&SCR used a 96 lb./yard rail while standard bullhead rail weighs 95 lb./yard. The GWR widely used a 97.5 lb./yard rail coded "00" and all fittings were thus marked.
The wagon was purchased to assist with permanent way work on the Bluebell Railway and arrived on 8th. September 1981.
