[11] The following table summarizes the class: In 1998, OSE began to receive the Adtranz DE2000 diesel locomotives, which were ordered at a cost of DM 210 million in 1995.

[3] These dual-engine dual-cab locomotives were related to FS Class E.412 and EU43 series for PKP and were based on the Octeon platform.

The MTU 12V396TC13 engine was virtually the same as that used in AEG/LEW-built InterCity DMUs (AEG DE IC-2000N) a decade ago, and this commonality was desirable; the engine pair delivered 2.1 MW (train heating could consume up to 500 KW of power from intermediate DC link as there was no separate head-end power generator).

[citation needed] The locomotives used steel from Poland's Pafawag, aluminium roof panels from Derby in the United Kingdom, AC motors and alternators from Adtranz Austria, while the bogies were Flexifloat (made in Kassel), also used in German InterCity Express.

Colour scheme of the diesel-electric locomotives consists of a blue trapezoid within a white trapezoid, with cabs painted red and cab fronts having large white polygons (giving rise to the nickname "Marlboro," from resemblance to the well-known brand of cigarettes).
