type, meaning that each axle is powered separately. The axles are installed in pairs on two bogies. The bogies had lighter, welded construction which gave the whole vehicle better contact with the rails. The engines used in EP02 were not modern ones, and had a large weight compared with power and small rotation. The engine contained two engineer's compartments on each end, with all the devices necessary for running the locomotive inside. The engine and high voltage compartments were situated in the middle part of the body.
