In 1964 a GS class open goods wagon number 8726 was converted to carry a Hydrochloric acid tank. The sides were removed but it retained its ends.  By 1970 it was painted in a pale livery (possibly white or light blue). Its ends  showed traces of Indian red beneath the body colour.   Photo at right is of JGH 8726 in 1970 (Don Finlayson).

JGH8726 was written off in 1972 and the tank transferred after modification to include a bolted end to another a similar chassis from a GST class open numbered 6620. This wagon was finally written off in 1982.
