John-Thanks for the information and the useful tools. They look like exactly what I need.
I'm in the final stages of the U30C I posted earlier. Adding a few more details and then will weather. In the meantime, I have started working on this Lionel SW900. Added Kadee couplers and did some pilot work. Just need to do some touch up and a bit more sanding. Pretty straight forward. Like the U30C, I'm on the home stretch with this one.
