Testing recently acquired vintage freight cars.
Still getting shorts. Think I got most of the truck shorts fixed. All metal wheels and axles don't 'play well' with an all metal truck. Even the original wheel sets in the metal trucks are shorting on curves. I'm assuming the previous owner had no problem since he, probably, only ran 8-15 car trains. I'm finding the drag on a 45 car train on curves, even 48" minimums, have the trucks pulling towards the center and touching the metal wheels.
Video: testing the mainline using my 'all plastic/resin' cars: no problems.
