The heavyweight B&O coaches I remember used ice air-conditioning.   Maybe this was replaced.

I was searching for information on this system without much luck, and came across this thread. The York Ice Machine Company equipment that the B&O started to install in the 1930's was a mechanical cooling unit powered by a gasoline engine, with the coolant then sent through ceiling coils.

Does anyone have drawings or photos they could pass on to me of the York A/C system equipment used on B&O heavyweight cars?  I have some Branchline Train cars for B&O, but BLT didn't mention York equipment in their drawings of underframe options.  Thanx--nor-rail.
