         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.
