I'm curious. I have brass track on my layout, because No one has enough nickel silver straight track, and the brass was cheaper. everyone is always freaking out about how bad Brass track is for trains, but i have so far had no trouble with it at all. I'm not cleaning my track every few months, and its still shiny. Maybe my basement is an ideal condition for brass track, but i would imagine that would be pretty bad. Is brass something that takes a long time to get bad?
