DB Class E 410

The DB Class E 410, renumbered Class 184 in 1968 and nicknamed Europa-Lok, was a small group of four-current electric locomotives that the German Federal Railways ordered in 1963 for through services from Germany to France, Belgium, Luxembourg and the Netherlands, whose rail networks used different electrification systems. Five prototypes were built between 1966 and 1967, all with a mechanical part made by Krupp. Three of them carried a thyristor-based traction circuit made by AEG, the first of its kind in a locomotive meant to cross electric frontiers, while the other two carried a conventional circuit from Brown Boveri. After extensive trials in several countries they ran on domestic and international routes, including Trans Europ Express services, until the end of the twentieth century.
