Most of my train inventory is Pennsy equipment, but I do have some trains from roads that interchange with the Pennsy. One is Southern Railway. Here is a SR passenger train headed by F3s and pulling some heavyweight cars. The concept is the SR train pulls in, drops off the cars that are then picked up by a Pennsy GG1 that takes them to New York City. This was an actual move in the 40s.
The Atlas' F3 paint scheme was exactly what I needed. It was used into 1949, the era of my layout. The simplified green scheme came out in late 1950. Notice the streamlined number boards on the Phase 1 engine. Outside of high-end brass models, the only other model to have this feature that I know of was the recent 3rd Rail F3s.
The coach and sleeper are Lionel, the GG1 is MTH.
