Re: UP B-50-40 from IM UP B-50-52 kits?

I don't know how much this will help, but you can get the 10/12 roofs from the old McKean PS-1 kits. You would have to cut them off as they are molded integrally with the sides and ends (I have some McKean kits if you want to buy some cheap). The 6' doors of the B-50-40 were 7 panel, not six panel. Such doors are available, including from Kadee, which should be perfect. My ignorance of B-50-40 decals is comprehensive, so help in that regard will have to come from others.

Subject: [RealSTMFC] UP B-50-40 from IM UP B-50-52 kits?

I made a blooper bidding on some IM boxcar kits at an NMRA division meet. I wound up with 3 1957 built B-50-52 PS-1 cars instead of cars I could use built as is in my pre-1955 model era. The kits only cost me a total of $14 for the trio so not a great financial loss. I didn't realize how late they were until I got home and started some research. Relying on, the only UP Pullman box cars built prior were the B-50-40 series from 1948. So the question is can these be backdated from a B-50-52 to a B-50-40 at least superficially?

I would need

  • Pullman 10/12 roofs to replace the kit 12/12 roof.
  • Superior 6 Panel Doors for a 10'6 car to replace the Pullman doors
  • Appropriate 1948-50 era decals
That would be enough for me. If it were an SP car these days I might be a little more fanatical. At least the roofs and doors are separate parts. I don't mind spending a few dollars to a little bashing to add some variety. 

The kits were old enough that they were marked "Manufactured in Colorado by Intermountain Tooling Specialist Inc."
