While fixing trains I am amazed at some of the repairs I see.
I had a KW transformer a few years back that had a new cord installed. A soldierless repair. They stripped the original cord and tied the wires to the ends of new cord. Then wrfapped the whole mess up with Scotch tape!
I just had a soldierless ZW that used crimp connectors on the stubs of the original cord a few weeks ago that got me started on doing a thread with pictures.
Then I just opened this one up last night. This guy had a soldiering iron, but left the original cord end there. The brown one is the new one, the original black one has some tape wrapped around it. This is a postwar SW transformer.
A few years ago I had a Lionel Standard gauge 10 loco with WOODEN wheels. There was a wire out the back to get ground from the next car. The guy was a paperboy in the 1950s who liked standard gauge. He painted everything silver, and made it run. He said he made the wheels in shop class with a lathe.
