Novelty 2026: The six-axle electric locomotives of class E 669.1 have proven themselves in heavy freight traffic for more than half a century. They were developed from the two prototypes of class E 660.0, with the aim of avoiding freight trains previously operated in double traction. Delivered by Škoda to the Czechoslovak State Railways (?SD) in the early 1960s, the total of 150 units built were used on the DC network in the north and east of the former Czechoslovakia.
