I have a Lionel Polar Express that I have been running for the last 3 years at Christmas, total run time about 30 hours. I have judiciously put a drop of oil on all the moving parts that are visible but I'm thinking about the internal parts - gears and such. I went to Lionel's site and, unless I missed it, didn't see anything.
Are there any parts under the shell that I should lube - or should I just say the hell with it and run it the way it is?
