3d printed and arduino powered. Detects train from either direction.

Nice. I’ve not looked into any of the stamp computers, but I get the concept and could probably handle the programming with a little brush up. I have a 1:1 signal that I’ve yet to put up. I wonder if I could find a servo powerful enough to handle an aluminum gate arm about 4 foot long.

Looks good, Tom…

Nice Tom, looks workable.

The targets are too far apart, are hard to put together and look awful, so I’ve redesigned them.
