Description

The Nederlandse Spoorwegen (NS) Class 1700 electric locomotives were built by Alsthom in 1990-1994. 81 of these locomotives, numbered 1701-1781, were built.

The Class 1600 was ordered in 1978, after several types of locomotives were tested in the 1970s. One of those was the French Class BB 7200, on which the 1600 is based. The 58 locomotives were delivered between 1981 and 1983. As a result of their delivery, the old Class 1000 and Class 1500 were taken out of service.

Thanks to the electronic power control, these locomotives were the most economical but also the most powerful locomotives that Dutch Railways had.

The Class 1700 are similar but not entirely equal to the Class 1600/1800. The newer 1700 series have updated and extended electronics, a newer safety system (ATB phase 4 vs ATB phase 3 in the 1600 series) and a different braking system. The locomotives are fitted with monomotor bogies.

Most visual difference between the 1700 and 16/1800 series is the automatic coupler on the 1701-1728 subseries. These locomotives are used with DD-AR double-decker coaches in a push-pull setup and treated as an EMU. The couplers, from BSI (Bergische Stahl Industrie, Germany), allow a mechanical, pneumatic and electrical connection between two DD-AR sets. From the remaining 1729-1781 series a large number are converted to be used in push-pull sets with coaches from the rebuild ICRm series. Several of these coaches have been rebuild with a drivers cab, allowing the loco to be remotely controlled. When not used in push-pull service, the loco is used in regular trains, available for maintenance or as reserve.

Names

In 2010, the Dutch Railways took a few class 1700 out of service because there wasn't enough work for all locomotives. Number 1735 has been scrapped, due to a devastating fire, which occurred on 24 February 2000 in Venlo. Refurbishment was too expensive, so the loco was scrapped in 2002. Some locomotives class 1700 carry names of villages in the Netherlands, the table underneath shows which engines.^[2]
