I just revived a train layout from 20 years and 3 cross country moves ago. Approx 4' x 8' HO Scale, multiple levels. I had to saw it in half to move it from a New York apt 20 years ago, and it now lives in a huge garage. I got it reassembled and am getting the power gradually restored. It's amazing how much you can forget in 20 years, And those masking tape labels on loose wires don't stick anymore.
The rolling stock is all made from kits from the late 40's, track and switches by Atlas.
I'm having problems with the cars derailing, both on switches, and curved track. I don't remember this happening in the past. Please help me with some suggestions as to what to look for.
Thanks for any comments.
