I don't think our club has any problem with oxidized track. But some of our club track is pretty grimy. I mean actually, visibly grimy. Probably, it's 10 years worth of electrical carbon and finger oil and dust, combined to make a quite non- (...) (21 years ago, 30-Apr-03, to lugnet.trains)

I had the same thought. Here's a few more I did last night of the point at which the motor's wheel touches the rail. They're a bit closer. (URL) surprised at how small the point of contact is, but it does explain the incredible reliability of (...) (21 years ago, 30-Apr-03, to lugnet.trains)
