EP02 is a name for a Polish electric locomotive. It was made for passenger transport purposes.

Technical features

Few 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 machinist 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. Based on the agreement with "Contractors Committee for the Electrification of Polish Railways" England was supposed to deliver eight sets of electric equipment - exact for the pre-war machines EL100 (EP01).

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 spinning after reaching 70 km/h speed, inconstant drive and vertical shakes. The faults were systematically corrected, and the experience was used during designing the ET21 and EU06.

Production

Exploitation

All the EP02s operated in Warsaw in the beginning, but soon they were moved to Łódź. Once there were enough EU07s, all EP02s were moved to Dębica. In 1971 the last three machines were retired and moved to work as heating engines (used to heat cars during longer stops at stations). This prolonged EP02's life by 24 years, as EP02-07 was working as a heating engine in Zakopane until 1992 and EP02-08 in Przemyśl until 1996.

During the exploitation locomotives were systematically modified, adding automatic brakes and heating systems.
