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.

. Once there were enough EU07s, all EP02s were moved to Dębica. In 1971 the last three machines were retired and reassigned to work as heating power supplies (used solely to supply electric power from overhead to heat cars during longer stops at stations, it involved parking them at selected stations and removal of most of the electric, brake and control equipment, retaining only the pantographs and switches associated with the HEP supply). This prolonged EP02s’ life by 24 years—EP02-07 was working as a heating power supply in
