The minimal instruction sheet that came with my Baby Blue Comet 'O' set showed lubing the engine but did NOT mention anything about oiling the tender axles/wheels, so I'm ASSUMING that they don't need oiled. But, wow, that's just a wild guess.
In addition, the 4 car passenger set didn't have any instruction sheet at all. NADA. Seems like there should have been since usually it explains things like taking the roof off, changing the light bulb, etc, and other features (like remote uncoupling). Since the truck structure is identical to that of the tender, I'm wondering if oil needs applied here too. Or not. It looks like metal axles in a metal journal, not the slippy plastic like on Railking cars.
On my 2 Railking passenger sets (11 cars total) MTH in an email response to me told me that they do NOT need oiled. I have never oiled any of my Railking rolling stock and in over 11 years have never had an issue.
Thus, I'm thinking that maybe the tin-plate cars don't need oiled either.
Do they?
