Interesting Robert, I must try that on mine. I saw one with Lazerglaze and it looked great.
I agree about the mounting holes for the detail bits, the 47s are the same. But I think they can look good. The Bachmann's bogie sideframes are a letdown for me, they need to be raised and maybe narrowed. The front cab windows are a bit small too.
My 37 doesn't have traction tires, I think they did away with them on later models, it runs lovely and is a good strong puller.
Pictures Robert, pictures!!!!
