I was wondering if it would be better to solder all track joint, or do I just stay with the rail connectors? Or would jumpers simply be better for expansion or contraction, due to environment changes? I haven’t had any problems yet, but am concerned about my track health longer term.
I wouldn’t solder every connection, but if you don’t have a feeder on each rail, joint you might want to solder some together.
If you do solder each joint, any expansion or contraction might interfere with roadbed alignment, causing major problems down the road. So while you can solder joints to help with electrical problems now, you want to find a balance for other potential problems.
