- My understanding is that coah heating started with "nothing",
- then progressed to coal fired stoves. (These, combined with wooden
- coach construction made for some nasty fires, in case of wrecks.
- (There's a bridge wreck in the US (Ashatabula?) and others, everywhere.
- I vaguely recall that some of the Transiberian stock is heated by
- individual coal fired boilers...)
-
- As i recall, there were two "essential" developments:
- reliable regulators to reduce the pressure and
- reliable hoses/joints to deliver it.
- I suspect that the proof_in_practice of the air brake, and the
- demostration that it WAS possible to run "plumbing" along a train and
- make it work had a bit to do with it.
-
- To round out the discussion, steam was used, on some cars, to power
- an absorption type air conditioner.

- Just another pipe, tucked under the tender, visible on close inspection
- sometimes identifiable by being "thicker" due to insulation.
