Hello, my son and I have amassed a bunch of track from various sources, both new and used. When we run the trains or even just a single locomotive to test things, we get stuck sometimes as in there's no power as some tracks. Some just don't seem to have continuity. Is that a simple connectivity issue or should we figure out which tracks these are and toss them?
Thanks in advance for your help.

Hello everyone. I'm completely new to model trains so be patient

My 7 year old boy is a train nut so I got a bachmann set with the old NS passenger locos. I've added a bunch of freight cars as well as tracks so it's getting some size to it now. All that said, I have 2 questions that hopefully someone can answer.

1) The locomotives spin their wheels when pulling cars, but they operate perfectly normal on their own. What needs to be done?

2) He's interested in getting some freight train locomotives such as UP, etc. I see some advertised on E Bay or Amazon that are HO scale. Will they work on the bachmann set or do they have to be made by bachmann in order to work?

Thanks very much for your help!
