- If you ever have a chance, buy "The American Railroad Passenger
- Car". This book has a superb discussion of the technology of passenger
- car equipment including heating.
-
- Basically, the answers to your questions are i) Yes, the steam did
- come from the locomotive boiler, though not always directly; ii) Yes,
- generally the steam pressure in the passenger area was very low; and
- iii) I would guess that the steam heat connection came off the
- auxiliary steam manifold which was usually located on the top of
- the firebox. Steam heat connections were provided on the pilots.
-
- The answer to ii) begs a large number of questions. I do remember
- that a large number of techiques were tried over the years. Often,
- the actual heaters were water radiators. Each car had a self
- contained water circuit with a water heater which used the steam to
- heat the water. This technique had two advantages. It could be
- retrofitted to the older stove heater systems. It kept the steam right
- away from passengers.
