Hi Ukaflyer,
I plan to pick up an Atlantic body (if I can't find the axle). My luck, everyone will be charging a fortune or there won't be any. I will be selling off old hopper bodies, and flat cars, as I want either American Models, S Helper, MTH or K-line easy rolling cars.
My soundless Berk was pulling 13 cars and slipping with traction tires. I like 20 plus car trains, so have to get better rolling cars.
