The NS Class 1600 is a type of B′B′ electric locomotive built by Alstom between 1980 and 1983 based on the SNCF Class BB 7200, and in use by the Dutch Railways since 1981. They were styled by the French industrial designer Paul Arzens. The Class 1600 was ordered in 1978, after several types of locomotives were tested in the 1970s. One of those was the SNCF 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 units were taken out of service. Thanks to the electronic power control, these locomotives were not only the most economical but also the most powerful locomotives that Dutch Railways had. NS/Railion Class 1600 In 1999 the freight division of NS, NS Cargo, was sold to Deutsche Bahn became part of Railion as Railion Nederland. The locomotives that became the property of Railion kept their old number (1601–1637). No. 1637 was repainted red as an advertisement for the Dutch brewery Heineken and was repainted in NS Yellow in 2004. Currently, Railion Nederland is looking to replace the Class 1600 locomotives with new multi-current locomotives type BR 189 from Germany. In early 2008 these started running into the Netherlands from Germany. NS Class 1800 The locomotives that went to NS-Reizigers (1638–1658) had their numbers raised by 200, thus keeping their number but now in the 1800 series. In later years 10 more of the 1600 locomotives were sold to NS-Reizigers and subsequently renumbered to the 1800 series. The 1800 series was now 1823, 1824 and 1826 to 1858.
