Title says it all. What size brass wire do I need for as close to scale handrails and grab irons and the like? I have an IHC SD-35 that came with molded on grab irons and ladders as plastic handrails and I was wanting to superdetail it by changing all these to wire and painted properly to match the true CSX Stealth scheme. This is my first attempt to superdetail any rolloing stock and I want to get it right from the beginning, any of you out there willing to help me out suggesting ways I could improve the project let me know. I am going to post an official project report in the Ho Scale forums once I can get some pics of the initial Locomotive before any modifications are made to it.
