For the first time in Sydney, fluorescent internal lighting and air suspension bogies were used. The initial 40 cars were used in power door sets, the remainder in non-powered door sets, and they replaced the remaining wooden bodied trailer cars. In 1987, W-set trailers T4834–4838 were converted to manual door M-set cars by having their power-doors disconnected, and rewired from 120- to 32-volt operation.
