Australian rail operators took delivery of 137 ALCo 'World' DL500B locomotives, all but 6 of which were dual cabs, although the 'B' end was not particularly aesthetic. There were no restrictions on B end leading, but generally it was not that common, crew preferring the streamlined 'A' end.
On 11 January 1991, Australian National's 963 was photographed at Roseworthy, South Australia, shunting hoppers while working a Tarlee to Port Adelaide grain train.
Already looking a tad unloved, 963 would survive over four more years in service, though I'm pretty certain it never got a decent wash from the time of this photograph until final withdrawal.
Note the Country Fire Service truck in the background.
