PKP class EP02
Encyclopedia
EP02 is a name for a Polish
electric locomotive
. It was made for passenger transport purposes.
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.
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.
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.
, but soon 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 operation, the locomotives were systematically modified, by the addition of automatic brakes and heating systems.
