I recall reading Ed King's report many years ago that when the crown sheet let loose on the N&W Y6 #2153 in 1955, the pressure was "only" 125 PSI, not the regular operating pressure of 250 PSI or whatever that engine was set up for. That one didn't launch because the pressure was that low and couldn't blow out the connections beneath the firebox for a start.

The incident happened about 4:30 AM.  The nearest residence to the explosion was
about 200 feet away.  According to the Roanoke newspaper, it never woke the
inhabitants.

The traffic control system was knocked out and with No. 41 closing, the dispatcher
called R. R. McDaniel's (NS Gen'l Mgr - Motive Power and Equipment) father, who
was a signal maintainer, to investigate.  He put the motor car on the track at
Wytheville, scanned the pole line and collided with the remains of the Y6.
