Tri-ang's Diesel Switcher was another item that was produced for the Canadian and Australian markets. It was based on the RS-2 Class (North America) and Victorian Railways T Class (Australia) locomotives.
I believe that the US company ALCO built 374 of the RS-2 Class between 1948 and 1950, with a further 9 being built in Canada by MLW Subsidiary, while Clyde Engineering of New South Wales built 95 of the T Class.
The model locomotive was produced between 1958 and 1967 had a working headlight and came in various liveries that were all based on Canadian and Australian outline. Originally they were produced in Yellow, Maroon and Green liveries but, latterly they seem to have been produced in yellow only.
Initially they all carried the Running Number 5007 although, in later models, this was switched 7005.
Most of them had TRI-ANG RAILWAYS printed on both sides of the loco but the ones for Australia carried TRANSAUSTRALIAN RAILWAYS instead.
The locos were sold both individually (as R.155) and also as part of the Diesel Freight and Transcontinental Freight train sets.
