NS placed a €510m order with CAF in December 2015 for 118 of the 1.5kV dc suburban trains, which are based on CAF’s Civity platform. The order comprises 68 three-car and 50 four-car sets.

The trains are due to enter service from next year as part of a €2.5bn programme to expand and modernise the NS rolling stock fleet.
