NSWR   GS  LPG Rail Tank Car

10 of these wagons were built by Commonwealth Engineering at Granville, under licence to the Union Tank Car Co., between 1964 to 1967 and were numbered GS400 to GS409. They were privately owned by the Gas Supply Co. Ltd of Melbourne and painted in their retail brand name of Speed-E-Gas. As Boral had acquired the Gas Supply Co., in 1964 a small Boral logo appeared on each end of the tank.  

These were the first privately-owned wagons to be approved for operation on broad and standard gauge tracks through the bogie exchange plant at Dynon. In 1974 three wagons were sent to Victoria and re-branded Heatane Gas later in 1978 a fourth wagon was re-branded Aftrans to carry Anhydrous Ammonia.

A comprehensive article by Neil Cram appeared in the Australian Model Railway Magazine in October 1989 detailing the colourful history of these wagons.
