I am setting up a simple LGB layout. I would like it to go along the wall, stop, reverse and then go back. We are putting it in a store for fun. I have no idea how to make it automatically stop and then reverse at each end. Can someone help??

Add an automatic reverser unit. These are made by LGB, AristoCraft, Split Jaw, etc. Alternatively, if you are good with a soldering iron, you can make your own for under $10 using internet surplus parts. Schematics are included:
