To overcome a temporary car shortage, some cars from South Australia were leased from Australian National Railways (ANR). The cars took a while to arrive as there were union problems in South Australia due to train service cuts.
In ANR service the cars were already classed BK.
Cars 702 and 703 entered passenger service in Victoria as BK 1 and BK 2 in 1983. In about 1992 the cars were returned to South Australia.
Seating capacities for each car was 56 passengers.
Car 600 entered passenger service as BKL 3 in December 1983. About 1992 the car was returned to South Australia.
Seating capacity was 64 passengers.
