I have a LionChief Plus 2-8-2 Mikado that has squeaked from day one. I have oiled every rotating, sliding or otherwise movable part, but the squeak persists. I removed the boiler, re-oiled every part from the top. I turned off the sound, the smoke and run it alone on the track, but the squeak persists. It's become more of a whine than a squeak more recently. It only does this in the forward direction, not in reverse. Running it in reverse, it is dead silent.
Any ideas out there? Should I dip into a bucket of oil? I am about to retire it because of the noise.
