- On the USRA light mike on which I worked, there was a pressure regulator which
- led to what must have been a 2-1/2 or 3" pipe. This was routed down the back
- head and through a flexible coupling to the tender, and then to the back of
- the tender. Normal operating pressure in the steam line was about 30
- pounds as I recall - though since most of the traps on our cars were
- sorely in need of rebuilding (the expansible doughnut gaskets needed replaced)
- we rarely operated the steam heat on the tourist trips upon which I worked.
- That made for some chilly starts in October in Ohio!
