Everyone has some old brass track around, and it is just plain awful to use. Brass oxidizes, and the oxidation is non-conductive, so you have to continually clean it to get power to your locos. Nickel-silver track oxidizes, too; but the oxidation is conductive - so you don't have to do anything to it!
But what to do with the old brass stuff? Here's a way to use up your brass track. This line with the hoppers on it is brass - and it is a fake line, it just runs between two fake tunnel portals on the layout. It doesn't connect to anything, and it is not powered. My backstory is that is was abandoned when the tunnels were bypassed by that nice nickel-silver line in the foreground. I just stash my seldom-used MoW cars on it.
