Friction is what our locos need to move. Ron, have you used it on grades, say around 2%+?
Mmmm, the smell of Brasso. I'm glad I got the tan boots, not the black ones...G.I.'s, remember polishing the BRASS? Grrrrrrrrrrr!
A friend of mine told me about the high current/voltage rail cleaner, this work on the basis that when a loco wheel, passes over some dirt that collected on the rails, a high charge surges through the rails, and it disintegrates the dirt, he also told me that it does not harm the engines.
Donno how that can be if a high charge passes through the rail while the loco is moving without doing any damage.
