Russ, it's a club with many volunteer members. I'm sure if you stop by they can point you to someone that can help you.
I would look on EBay for somebody who's selling Lionel trains and contact them. They might be an enthusiast's who could help with what you need.
Russ, this is a difficult skills to track down. I didn't talk with the people in the model railroad museums for very long. But I'm sure that, as suggested, you can find help here. I'm in New Mexico, and was lucky enough to find a retired engineer who would do work like this. In San Diego, I have no idea.
They have many experienced volunteers who I am sure will point you in the right direction
