Union Pacific EMD SD70 Ace Locomotive in Lego, scaled 1:16
Two years ago I made my first locomotive as a full Lego scale model, set to the relatively big scale of 1/16. It was an older type American Diesel-electric unit called SD40-2, made by EMD (Electro Motive Diesel). The warm response the model received encouraged me to build another one, and this time I aimed for a more modern type, also produced by EMD: The SD70ACe. This mighty machine is a six-axle, 4300- horsepower, AC-traction diesel-electric locomotive which was first introduced in 2004, and has been in production since 2005. The SD70 ACe is very representative for locomotives used by North American Railroads to transport heavy freights.
The locomotive that I replicated is owned by Union Pacific; a freight railroad that operates nearly 8,500 locomotives, from which about 700 are SD70 Ace’s, and is the largest in the United States.
This specific example is something special though. It is a so called Union Pacific "heritage unit". These are a total of six SD70Ace’s which are painted in unique commemorative schemes which are meant to designate former railroads which Union Pacific purchased or operated over former trackage. Locomotive ‘UP 1989’ is such a “Heritage Unit” and is exclusivly painted in the colors of “Denver and Rio Grande Western Railroad”, which Union Pacific acquired in 1996.
The Lego model consist of about 27.000 bricks, and was built in 4 months. It is about 143 cm in length (56,2 inch). The model was made from pictures and drawings found on the internet. It is fully detailed both, in, -and outside with modeled engine, electrical cabinets and cabin.
All decals were self-made as vector files, and printed and pre-cut at a professional company. Some retrofitted chromebricks are used.
This is also the first time I have used lighting in a model. Rob from www.brickstuff.com made it possible for me to make a realistic lighting setup without sacrificing any space for detail due to the very thin wiring, and even the ditch effect is onboard. For the same detail space reason I used the small battery boxes inlcuding switches from Brickstuff, and there are now two main switches to operate the external and cabin lights. It really adds to the realism of a build, and it will definitly not be my last work with lights mounted!
