Technical Data
As the EP08 is tightly based on EU06 and EU07 locomotives it is important to compare those series while writing about technical features. EP08 is a Bo-Bo locomotive with four axles mounted on two bogies. Each axle is propelled separately by an EE541a traction motor. The cab has two identical crew compartments on both ends.
The main differences between EP08 and previous EU07 locomotives are as follows. Transmission was changed from 79:18 into 77:24 what resulted in possible top speed of 160 km/h. However, the machined performed poorely driving with such speed, so the top speed was set to 140 km/h. First five units were equipped with plain bearings what proved insufficient for higher speeds and as a result all these locomotives were rebuilt as EU07 series (numbers 241 to 244). In later units roller bearing's were used.
Another significan change comparing to EU07 series was exchange of traction motors to newer EE541g type with higher isolation class. Windscreens were changed to 14 mm thick ones with heating layer and pneumatic wipers. However, some solutions from EU07 locomotives which were rather faulty, were copied into this machines, like poor access to internal devices.
EU08 is suited for multiple steering work. Locomotive's cab resembles those of EU06 and EU07, but have different, orange and brown painting. Since June 2007 PKP Intercity has started repainting those machines into new, blue and white colours.

Famous quotes containing the words technical and/or data:
“The axioms of physics translate the laws of ethics. Thus, “the whole is greater than its part;” “reaction is equal to action;” “the smallest weight may be made to lift the greatest, the difference of weight being compensated by time;” and many the like propositions, which have an ethical as well as physical sense. These propositions have a much more extensive and universal sense when applied to human life, than when confined to technical use.”
—Ralph Waldo Emerson (1803–1882)
“Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.”
—Grace Baruch (20th century)
