We have an On30 steetcar xmas trolly at my office and it works fine, but it is squealing loudly all of a sudden. Is there any specifics on lubricating it and which oil to use? Light or heavy? also lubrication points? THank you.
Is this your streetcar?

I think so! . I tried putting some Bachman gear oil on the worm gears and wheel gears, but still squealing.
choochoo-
You can get a squeak anyplace to pieces of anything move against one another. It sounds like you have a pretty good start so lets go to the next step. Put a tiny bit of plastic-safe oil in each truck journal -- the pits into which the ends of the axles fit. A bit of graphite will work, too. Then check other articulating points in the mechanism. The motor should be lifetime lubed but drive shaft supports, "differentials," the gear train and gear axles can all develop a squeak.
