Worth a try I guess...... Paint the lagging so the string is sealed, otherwise it just absorbs water and/or oil depending on where it is.tom_tom_go wrote: ↑Sat Jan 20, 2018 7:17 pm Thanks Andrew, I think I will try lagging first before anything else.
The Garratt has insulated steam lines and superheating and it is still the wettest loco I have. Second wettest is probably the Shay which isn't superheated, but the thing both have in common is very long external exhaust lines and more than two cylinders.
FWIW. I tallied up and half my locos have a flue superheater, while the other half don't and have external main steam pipes. I don't notice any major differences in wetness at the front end, although I don't run very often in temperatures below 20C.
With respect to cylinder drain cocks, have you considered fitting the exhaust intercepting valve that Roundhouse use on the Silver Lady. I assume they'd sell you one if you ask nicely and you already have your SL for reference to work out how to fit it into the steam pipes. No drilling, tapping, etc. and no clearance issues.
