Summary: You're talking about FELONIES here. I just wanted to point out that it is VERY ILLEGAL to mess with RR crossing signals. It is done by shorting out the tracks, and there are several insulated sections of track on each side of the crossing so the signal can tell which way the train is going, if the train is stopped near the crossing, etc. It varies from crossing to crossing, but the standard crossing does have some RRL (relay to relay logic :->) to tell which way the train is going. On the illegality note, remember if you screw it up and people die, you've just committed MURDER. Trains are big and fast and kill people. Actually, trains don't kill people: people kill people. Enough of that. Todd
