CFR (Call for Reference) on the above. as I believe it to be
Bull****..... the only Steampowered Trains still in existance,
and in commercial service are in third and fouth world countries,
and mostly run on diesel fired boilers. Turning big air compressors
with diesel engines is a very wastefull way to move Railroad Rolling

They don't always have a IC engine on board for the compressor...
Some recompress themselves with exhaust air,then heat the air recovered in
the boiler.

Many mine trains also run on air since sparks can be deadly in the right

They usually are either diesel air or stored air trains.
