The ES 499.1 electric locomotive is one of the best-known vehicles of the Czechoslovak State Railways. Developed and built by Škoda in Plzeň, these locomotives were technically among the most modern in Europe at the time. As the world’s first multi-system electric locomotives, they featured thyristor pulse control, which enabled infinitely variable and particularly sensitive power control.
A distinctive feature of the Czechoslovak railway network was the use of two power supply systems: 3 kV direct current and 25 kV 50 Hz alternating current. To enable trains to run continuously without changing locomotives, Škoda developed the dual-system electric locomotive ES 499.1. The first prototypes were built in 1980 and 1981, with series production beginning in 1984.
The four-axle locomotive, with a Bo’Bo’ wheel arrangement, was 16.8 metres long and weighed around 87 tonnes. Four traction motors delivered about 3,480 kW under direct current and about 3,060 kW under alternating current. The maximum speed was 120 km/h. A modern thyristor control system enabled precise power regulation, making the locomotive suitable for both passenger and freight trains.
