I just got this Lionel 41 switcher on a Stout auction. It was in fantastic shape with little run time. I added a small warm white LED for the front headlight (I can't believe they go around in the dark), and a little person inside. I had to put black paper underneath the 3 open smoke stacks to stop the light bleed. I'll be adding a small flashing red LED for the back light when they arrive in a few days. It may not be prototypical, but I will like it.
I think I'd like to add a brass bell to it. Does anyone have a suggestion on what to buy?
