Will Ebbert posted:What size wire do y'all use?
Hi Will...I agree with what Jeff said above: .025 wire matches the "factory" railings on many of the more recent locomotives. Some of the "older" modern locomotives (if that makes sense!) used .032 diameter railings. Just a bit too heavy IMO, but if you're a person who wants to keep everything uniform you should probably have some of that on hand as well.
In the case of the MTH Premier VO-1000 pictured below, I used .032 wire on all the end railings and coupler cut levers to match the "factory" diameter; however, if I were to do it again, I would have used .025.
