From 1919 to 1953, the Chicago, Milwaukee, St. Paul and Pacific Railroad (known as the Milwaukee Road) had these five General Electric-made behemoths pulling trains under the wires from Chicago to Seattle. They were called the Bipolar's for each of the locomotive's 12 motors had only two field poles, mounted directly to the locomotive frame beside the axle. The motor armature was mounted directly on the axle, providing an entirely gear-less design.
These locos were so powerful they could out-pull modern steam locos, and what used to take two steamers took just one bipolar. However, after a disastrous 1953 rebuilding by the railroad's company shops )(who had no clue how to work on a electric loco) the engines were prone to failures and even fire. And so, in 1962, four of them were scrapped with the lone survivor, numbered E-2, towed to the Museum of Transportation in St. Louis Missouri, where it has sat silent even since.
This model was inspired by a 1999 version of the engine built by user legosteveb. I recreated the actual orange, red and black color scheme used on the loco when it emerged from that 1953 modernization program, and revised the window arrangement. I also put pantographs on top, but they can only be used in the down position as they are WAY too tall for use with any of my tunnels or bridges when raised even slightly. The number board in front (and rear) should say "E2" in printed 1 x 1 tiles.
The loco is split in three sections as per the original engine. The front and rear section can pivot slightly to make the engine go around curves.
The wheels are jointed to the frame at the three wheel segments, with a center section all by itself. NOTE: This is where I am unsure about the wheels design. I think it will work, but if it doesn't, I will just redesign the middle wheels as the front two sets are, but with a single wheel instead of two.
The pantographs have an Achilles heel: they are too tall to extend upwards, so they must always remain down as far as possible to keep it from bumping into stuff. Even in this picture, they are too tall as I couldn't get the program to cooperate in lowering them, even though they do go down further.
