I have a Lionel 2034 that had a bent cab I fixed, but it ran poorly too. It would run, but only in super slow-mo, and that was when it would run at all. If I was really patient, sometimes I could get it to run a little after a few minutes, but it had minimal pulling power even then. So I took a shot at Lionel 2034 locomotive repair. It was successful.
The motor needed some maintenance, but it didn’t need any parts. Here’s how I fixed it in less than an hour.
