Steam locomotives ran at around 200-250 psi during the later part
of the steam era (early 1900s-1940s). Earlier engines ran at lower
pressures, mostly due to the metallurgy of the day. Don't know about
stationary steam engines, but likely they ran similar pressures, again due
to the materials available.
A locomotive fireman had to make sure to keep the crown sheet (top
panel of the firebox) covered with water at all times. Failure to due so
resulted in catastrophic failure.
