In the early 1960s, the former Czechoslovak State Railways (CSD) needed a new, powerful electric freight locomotives for the 3 kV direct current system in the northern and eastern part of the country. Experience with the E 499.0 and E 499.1 classes – originally developed as universal locomotives – showed that they could be better utilised in passenger service. Locomotive E 499.157 was therefore modified during production for use in freight service and designated the E 469.001. This locomotive had the same power but was equipped with a modified wheelset gearbox by the manufacturer. The service weight was also raised to 88 tonnes by a ballast weight. The series machines had a modified locomotive body. Unlike the E 499.0 with six circular windows per side section, the locomotives of the E 499.1 and E 469.1 classes had four angular windows installed. With a continuous output of 2,032 kW, they were able to achieve a maximum speed of 90 km/h. A total of 85 Skoda locomotives were delivered t
