Been playing around a bit with some basic powered rail layouts. They seem to work pretty well actually. At least as long as the gold holds out.
Only bit I need to work on is the carts tendency to hit the end of the line, bounce off the stone brake block onto the launcher and shoot off back the way it came. Guess I'll have to wire up an off switch for the upcoming launcher a short ways up the track. Hmm, wonder if a Detector rail would do the trick?
