Hello all, real world railroader here looking for some advice. I have no model train experience, but I would like to setup a simple oval around the Christmas tree. I received a Bachmann HO scale ES44AC (NS 8102) as a gift several years ago which I would like to use. I'm a little overwhelmed trying to figure out which controller and track I should purchase to go with this locomotive. I only plan to set it up under the tree so I don't need anything too fancy, what would you recommend? Besides some track and a controller, is there anything else I will need? Thank you.
