'''EP02''' (also manufactured as '''Pafawag 1E''') is a name for a [[Poland|Polish]] [[electric locomotive]]. It was made for passenger transport purposes.

==Technical features==
Improvements were brought in with this locomotive type. The front and back of the box had dragging and bumping devices installed. The whole body was given a more [[aerodynamic]] shape compared to previous models.
This machine is of [[Bo′Bo′]] 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.

==History==
After [[World War II]] almost no [[electric locomotives]] survived in [[Poland]], and local industry was not yet able to start the production of such vehicles. The solution for this problem was sought mainly abroad and resulted in a decision to buy some components from [[England]]. The design for EP02 by ''Central Rail Industry Construction Office'' in [[Poznań]] was ready in 1951. 

===Introduction===
In 1951 the design was sent to Pafawag, but the construction met with a few obstacles, mainly lack of material and parts.
The first locos were directed into [[Warsaw]]-Ochota railway district in 1953. Soon many construction faults appeared, like wheel spinning  after reaching {{convert|70|km/h|abbr=on}} speed, inconstant drive and vertical shakes. The faults were systematically corrected, and the experience was used during designing the [[ET21]] and [[EU06]].

|}

===Operation===
All the EP02s initially operated in [[Warsaw]], but soon were moved to [[Łódź]]. Once there were enough [[EU07]]s, all EP02s were moved to [[Dębica]]. In 1971 the last three machines were retired and reassigned to work as [[Head end power|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 [[Head end power|HEP]] supply). This prolonged EP02s’ life by 24 years—EP02-07 was working as a heating power supply in [[Zakopane]] until 1992 and EP02-08 in [[Przemyśl]] until 1996.

During the operation, the locomotives were modified by the addition of automatic brakes and heating systems.
