Cars 2367, 2368 were built and placed into service on the 'Spirit of Progress' train.
Cars 2339 and 2343 were destroyed in the Violet Town collision of 1969. They were replaced by new cars 2374 ( 1970 ) and 2375 ( 1971 ).
At 1984, Car 2373 is listed as NSW-VR Joint Stock, yet appears to have been issued to service as a car for the Brisbane Limited.
