The ČSD 169.001 (originally: E 499.5001 ) was the prototype of a planned generation of new electric locomotives for the Czechoslovak State Railways (ČSD), which was manufactured by Škoda in Plzeň in 1987 . As the first and only electric locomotive in what was then the Eastern Bloc , it received three-phase power transmission by means of static converters . It was sold by Škoda as type 85E . Due to the social and economic upheavals after the velvet revolution in 1989, the development was finally interrupted.

history

Since 1979, the German Federal Railroad (DB) had put into service the world's first locomotives with three-phase drives and static converters, the 120 series . With this new type of technology, it was possible for the first time to build universal locomotives that could be used in both heavy freight and fast passenger train traffic. Also the

As the first manufacturer in what was then the Eastern Bloc, Škoda began developing such a locomotive in 1985. Internally it was designated as type 85E, the ČSD provided the series designation E 499.5. In 1987 the test model was completed. According to the ČSD numbering scheme valid from 1988, it was given the number 169.001.

As of 1991, the 169.001 was rented to ČSD or its successor České dráhy for testing purposes . From the Nymburk depot it was used on the routes Praha – Beroun and Praha – Nymburk in regular operation. In 1994 Škoda sold the locomotive to the První správkárenská company , which continued to lease it to ČD until 1996.

From 1997 the locomotive was parked at ČMKS Holding in Česká Třebová . In 2003 the locomotive was returned to the manufacturer in Pilsen, where its components were used to develop the ČD 380 series . With this series, ČD has acquired new electric locomotives for the first time since 1992.

technical features

The locomotive body was equipped with two end driver's cabs, with the engine room in between. The locomotives originally had four low-speed, three-phase alternating current operated asynchronous motors , which were later exchanged for high-speed ones. They were regulated by four IGBT traction converters . In addition to the compressed air brake, the locomotive also had an electrodynamic brake.
