NS Class 1000

NS Class 1000 Electric loco

Prelude

In 1908 the first electric train in the Netherlands ran from Rotterdam to Den Haag and Scheveningen. It was electrified with a 10,000 volt AC power supply. After World War I the Dutch government decided to install a committee to investigate electrification of the Dutch State Railways, Nederlandse Spoorwegen, formed in 1917 but officially only instigated in 1937. For that, the committee members traveled the world to visit existing electrified railways. In the early 1920s they came to the conclusion that a 1500 volt DC system would be the best choice. Most Dutch electrified rolling stock were EMU's. During World War II the German occupiers used these EMU sets to haul heavy freight trains for their war effort.

Origin of the Class 1000

NS management already had contact with the Swiss company Oerlikon about ordering a series of electric locos before the war. They were to be based on the Swiss Ae 4/6 type. In 1942 the series was ordered, but the war prevented delivery. The order was subsequently changed to suit Dutch needs. The "Schweizerische Lokomotivenfabrik Winterthur" (SLM) would build 3 complete locos and deliver the electrical equipment for the remaining 7. These 7 would be built in the Netherlands, by Werkspoor. The series would be numbered 1001-1010 and had 6 axles in a 2-2+2+2+2-2 or (1A)'Bo(A1)' configuration. This configuration was already used successfully on the electrified railway network on Java, then a Dutch colony, but in the Netherlands it was a failure due to its complicated technology and high maintenance. The series was delivered in 1948 and stayed in use until 1982, despite its high failure rate. One loco, 1010, built by Werkspoor, is preserved as a static object in the Dutch National Railway Museum.
