Well, as I said I would, I've spent the last month working on and off on this 3-D drawing of a 55', all passenger McKeen Car, like the Cuyamaca, one of only three McKeen Cars still around, which I am acquiring soon, and of which I also wish to restore to a running factory like condition (minus the 5600 Cubic Inch monstrosity that Mr. McKeen called a 200H.P. engine.)
While working on this model, I had a question, what is the height center of the coupler? I know in real life, on the McKeen Cars at least, it was 35" about the head of the rail, but what is the measurement for regular O gauge (not O scale) railcar couplers? I don't know if I want to be able to run this with other railcars, or if I will want to keep it to scale to run only with other cars that I print.
Also, ColoradoHiRailer, if you see this, please contact me, my email is on my website.
