Hi John,

The cylinders won’t “stay warm” until the frames they are bolted to, are
also warm. Once I get to the point where the safety valves are lifting…that
is when I oil around and I stop and eat a sandwich! This gives the
locomotive a chance to warm all the way through, and more importantly….by
eating first, I don’t have to shorten my run because I am hungry! Learning
the ins and outs of each individual locomotive is what makes our hobby so
interesting. Each locomotive has its own peculiarities and they will run
differently each time we fire them up. Every day is something new.

Keith

Hi Keith,

that's a very good point and one I'd not considered. Actually I do
usually warm up the cylinders etc by running up and down the steaming
bay track a few times with the regulator just cracked open before
going out onto the main track. I must admit though that I do this to
heat up the 'Peek' piston valves and expand them so that they seal
properly rather than warm the whole loco up.
I think the loco warms up pretty quickly anyway as I have a very high
level of superheat judging by the way that the silicon O rings in the
steam distribution manifold have gone soft and gooey! I reckon the
steam temperature is at least 250° C. Now looking for some
high temperature replacements!
