Hello everyone, I'm new to this forum and new to the hobby. I bought a Kato starter kit and it's a lot of fun. My friend had a bunch of trains stored in the attic and gave them to me but they're really old. There's about 5 locomotives but none of them will run. When I place them on the track only the light turns on. I can see that on some of the engines they motor tries to turn but can not. So I think the gears need lubrication. I need your advice on the proper lubrication and ideas on how to get these old locomotives running again. Thank you for your help.
