If I were to go to Radio Shack, What kind of diode do I need to make my own reversing similiar to the Aristo-Crafts units being sold. I have seen pictures of them but can’t make out what the number is on the electronic piece solder across the joint…Thanks, Travis
Travis - just about any silicon diode will work to stop a train at each end of a point-to-point - I generally use 3 amp diodes but 1 amp will work with smaller engines.
This item from Radio Shack may be available at the local store

Yup. About anything you find in the drawer labeled “Diode.” Except maybe the tiny glass ones, but I don’t think they have any of those.
