Roger,
These tales have been distorted somewhere along the line!
The first one refers to "Princess Elizabeth" which had a core plug come
unscrewed in one of its pistons in an inside cylinder. (The pistons are
hollow). This took up the clearance between the piston and cylinder end
cover causing very serious damage to the piston, cylinder, slidebars and
motion work. The loco was retreived by Ian Riley's men, one of whom is a
mate of mine and gave me this info.
The second one refers to "Blue Peter" which was departing Durham with a very
high water level in the boiler. The driver was rather over enthuiastic, the
loco primed very badly, lost its feet and slipped so much that it destroyed
many pieces of motion work. This is from my mate referred to above who has
seen a video of the incident in which pieces of motion work can be seen
being thrown in the air! It is now part of a training video for aspiring
mainline steam crew. Apparently when a large locomotive primes badly the
solid water passing through the regulator valve makes it impossible to close
the regulator, the water then flashes into steam in the superheaters which
were very hot as the loco had been standing in Durham station for a while.
The vast volumes of steam produced then do the damage referred to.
