There was no "power source" as suchÂ… Head End Power (HEP) was still in the
future and would not have been available in the 40's and 50's. I'm also not
aware of many switchers with steam generators, although I know there were some.
During movement the car would have maintained systems using its own batteries.
Some passenger cars had small engine-driven generators but I am not near my
resource material to see what these particular cars had for power or A/C
systems. Once moved the car could be piped into house steam from the station.
Some stations maintained batteries on carts to hook up individual cars. In the
time frame you are talking, there were no major electrical connections car to
car, only steam. At that time steam provided both heat and air conditioning
via systems called "steam ejector air conditioning". The AT&SF was a big user
of the latter.
My guess is the railroads did not worry about passenger comfort when
transferring station to station. If the passengers got off, the transfer to
the new station was their problem, not the railroads. Remember, this is the
time when Robert R. Young reminded the traveling public that a pig could go
coast to coast without changing trains, but people couldn't. Not much has
changed, other than maybe pigs are smart enough not to use the railroad
anymore! <GRIN>
