BL 12 and 13 were renumbered from "Pioneer 1st" and "Pioneer 2nd" respectively, in 1921.
The "Pioneer" cars were built in 1893 for traffic on the Bendigo line.
The BL cars were removed from service in the early 1960's.
BL 12 and 13 were used on circus trains as accommodation cars for many years. Circus performers complained continually about the poor accommodation given, particularly when they were given lavish settings on overseas rail systems.
