In the beginning of the 1980s the Dutch Raiways needed new electric locomotives to replace class 1000 and 1500, and to extend the number of locomotive-hauled trains. NS class 1600 has been bought again from Alsthom in France. This time the class is based on SNCF (France) class BB 7200, and the locomotives have an unmistakable French outline. The locomotives have monomotor bogies and are chopper-controlled (variable frequency). They are capable of 180km/h, but restricted to 160km/h by line speed limits. A single locomotive is only allowed to operate at 120km/h. Multiple traction of two locomotives is in principle possible, but is forbidden because of disturbances in the signalling system.
The locomotives of class 1600 were used for all kinds of trains, from (the first series of) double-deck push-pull commuter trains to very heavy freight trains. They were the main locomotive class for the locomotive-hauled InterCity trains on Haarlem - Maastricht and The Hague - Heerlen. But now class 1700 electric locomotives (replaced in double-deck commuter trains by motor cars class mDDM) have largely replaced class 1600 on these lines, class 1600 will be used more and more on freight trains. Since January 1999 37 members of class 1600 are deployed by Railion, as the remaining 21 members are mainly used on double-deck push-pull trains (class DDM) and for international trains by NS Reizigers (NS passenger service). These are now renumbered in the 1800 series.
In August 2000 4 more members of class 1600 were planned to be transferred to NS-Reizigers, in 2001 locomotives 1634-1637 (including "Railion Red" locomotive 1637) were actually renumbered in 1834-1837. In 2002/3 10 more locomotives followed, for which Railion got 12 diesel locomotives class 232/241 of DB Cargo in exchange. All of these have now arrived, with 1623 instead of 1625 which was heavily damaged in an accident.
Due to change from locomotive-hauled trains to trainsets and push-pull operation, 10 locomotives were stored from summer 2005. Their numbers are 1823, 1824, 1826-1832 and 1838. All apart from 1838 were restored by June 2007, the latter was scrapped after an accident. Nr. 1841 was also stored during 2008.
After 20 April 2009 14 locomotives were stored (1823/24/26-37) because the coaches of classes ICK are no longer used, and ICL will also disappear. In September 1851 was stored. This leaves 1839/1840/1842-1850/1852-1858 still in service.
