Nostalgia & History > EMD Model 40 information sought

Could anyone familiar with the EMD Model 40 four-wheel "critter" advise (1) the wheel diameter; (2) voltage of starting/control system (assuming 32 volts); (3) nominal working voltage of traction system (assuming 300 or 600 VDC) and anything else that would be helpful for building a full-size replica from scratch. Since nobody wants to let go of any of the few derilect ones still around we may decide to build a shop switcher from an EMD cab and GE-45 tonner components.

Many thanks;

You probably know this, but there are several Model 40's in museums, whose staff might be able to answer your questions.

Probably the closest one to you is at Travel Town in Los Angeles, CA.  It's a former Navy unit that later worked for McDonnell Douglas.  It was operational, last I knew:

Congrats on your purchase of S/N 1835, was then later sold to the American Steel Foundry and renumbered 51. It then went to Borg-Warner and lastly worked at Calumet Steel as their No. 1.
