My O scale model train layout represents the section of the Pittsburgh & Lake Erie Railroad between McKees Rocks and Youngstown.

I modeled a 3D printed version of the P&LE's McKees Rocks Locomotive Shop, here:

OpenSCAD program: https://www.thingiverse.com/thing:2312384

I had to compress it lengthwise from 17 sections to 7 sections and I had to abbreviate the railroad name.

I learned from a member of the NYC Historical Society that the unfaded oval of bricks on each end of the prototype originally had a "New York Central System" logo. The P&LE was a wholly owned subsidiary of the NYC.

That logo was removed when the P&LE was given its independence when the NYC and Pennsy were merged to form the Penn Central.

In my alternate universe, the P&LE put their logo on the shops as the P&LE ran independently until 1992.

This thing is the P&LE logo. On my O scale model, a good size turned out to be 100mm in diameter. The 3D object was derived using the surface() OpenSCAD command along with a png version of the logo as found on the Internet. I created it as a 50mm circle originally so if you want a 100mm version, you will have to scale it up 200% in your slicer.

I used the 'cut' command in Slic3r to remove the background of the OpenSCAD stl file. I then created a 100mm background.

I printed the background using yellow PLA and I printed the rest of the logo in black. That way, I didn't have to paint it.

To use this in N, HO or G scale, you will have to scale appropriately.
