Power hungry? The DD35A should fill any appetite! Union Pacific ordered 15 of these locomotives in 1965, piggybacking on the cab-less DD35 which had come just before. Essentially a pair of GP35 locomotives on a single frame, these massive beasts were at home on the long grades of UP's mainlines. Early on, sand proved to be causing an issue in the electrical compartments. Solving this, large sandboxes were added to the outside of the walkways above the rear trucks. The Union Pacific fleet served well for roughly 15 years, but ultimately were replaced by more efficient and more flexible single unit locomotives. Aside from the sandboxes, recreated for the first time on this run of models, there were only minor variations in the UP paint schemes. We've captured all three here as well as another "what if" in today's flag paint scheme as well as two other plausible fantasy schemes for the Alaska and Santa Fe. Although no other railroads purchased any and none were preserved, we can still dream big on our model railroads. This new run incorporates all of the latest Lionel features - so supersize your roster today!
