I have always wanted a transfer locomotive to work between my steel mills and foundries, but the only one I know of was a model of the brass Baldwin DT-6-6-2000. Only time I have found those those was high dollar locomotives so I set out on designing and building my own. 

I stated by looking for a mechanism and frame. I wanted to use a good running engine that ran great at low speeds. I ran across a Kato SD40-2 that had electrical problems but for the price I pick it up. Once I found the issue and fixed it I had my base for the transfer locomotive. 

Using a SD40-2 Frame and trucks I decided to stay with the EMD look. A friend gave me a couple Athearn BlueBox GP9 shells. With the heavy loads this engine will be hauling it need dynamic braking so each shell had dynamic brakes. I made a few measurements on each shell and made the cuts and attached the shells together. The shells set higher on the SD40-2 frame then their regular GP9 frame so I had to add an additional steps. I used K&S .020 Wire to make the handrails, and with a few additional parts the locomotive was sent to the paint shop. 

The locomotives was painted in the KV&O experimental red painted scheme. The locomotive is ladled as a DD9C-2

Nice free-lance design. Now you need one without the dynamics.

Nice work !

A great project, Don.  I sent you a message on another forum, and a picture of a Pennsy loco, with dual motors.  I really like this project,

Mike.

I have a similar concept in

I have a similar concept in my "someday" folder. It's a pair of NW2s on an SD frame (an SD45 in the case of the drawing). The real challenges, beyond just the concept, are coming up with a design that keeps the weight more or less equal on both ends and to each axle, maintaining easy access to the engines for repairs, and not having more horsepower than the six traction motors can handle. That's why I went with twin 1000 h.p. engines instead of 1500 or 1750 of the 7-series and 9-series respectively. I didn't think about dynamic brakes as I see this as more of a yard goat or a plant switcher - relatively flat places were pre-extended range brakes wouldn't have helped much. However, a pair of them could easily be installed to either side of the cab. I call mine the SDT-20 (Special Duty Transfer, 2000 h.p.)

Don Dunn Done It

What a great locomotive Don. The Kato mechanism must pull alot of cars smoothly. Aj, what a great concept.
