Boilers are not cast iron just for starters

Not (usually..[1]) in locomotive applications for many years, but it
was the standard material for many boilers - including locomotive ones
back in the earlies.

The first commercially successful locomotives - and the first exported
- had cast iron boilers, after all..

[1] Does the replica of the Gateshead machine that masquerades as the
Pen-y-Darren machine have a cast boiler? Trevithick certainly used
'em..


I think you will find they were wrought iron for many years. Merthry
Tydfil was renouned for it's wrought iron.


Coalbrookdale, OTOH, was a specialist in casting. Pretty sure the
Trevithick stationary engine in the Sci. Mus. - that kissing-cousin
of Catch Me Who Can - has a cast boiler.
