Brought the RS-1/2 and the RS-11 back to the "shop" from Knowledge Park Shortline. RS-2 needed oiling, maybe; RS-11 was derailing at a turnout, sporadically.
Pulled the cab and walkway off; separated the halves to remove trucks.
One truck had a side frame that looked like it had been overheated or melted with glue. Don't know how it would have gotten hot enough to melt the plastic, but it didn't matter. The same truck showed a wheel set a bit out of alignment (bottom left in photo).
Fortunately, Atlas happens to have a full truck assembly for $5.20 plus a lot more for shipping! Will replace the whole thing.
Took the green RS-2 apart and oiled worm gear shaft/bearing, and other gear shafts and axles. Might help, might not.
Took the RS-2 back to KP Shortline and got three locos running again. RS-2 didn't seem to have the same problem with the turnout.
But, limit switches for the third train had some sort of glitch. Since the same sort of setup will be used for a second siding when Section 3 of layout is completed, borrowed the limit switch electronics from that siding for current siding. Will need to check out the electronics and see what's up.
Hoping we're good for now with locos.
