I’m working on finishing up a model of Conrail 3278, a patched ex-Reading GP40-2 and I needed to make number boards for it. Decaling them sucks, so I decided to just print some up and install those. In order to do that I needed to get the dimensions. Since I couldn’t find them quickly while Googling I figured the internet could stand to have this written down, so, here they are.

The Atlas GP40-2s, and I’m expecting other EMD units who’s tooling was not derived from Kato models (EMD SD35, SD50, SD60, GP38, GP38-2, GP40) share the same dimensions: .18″ x .06″.
