NS Mat '64

The NS Mat '64 or Materieel '64 were electric multiple units (EMU) built by Werkspoor and later by Duewag and Waggonfabrik Talbot between 1961 and 1976.

Materieel '64 is sometimes nicknamed 'Apekoppen' (literal translation: 'monkey heads') and 'Standaard Stoptrein' ('Standard stopping train') due to their distinct shape.

Plan V was, for many years, with 246 units (although only 245 were present at the same time), the largest series of Nederlandse Spoorwegen rolling stock, until the arrival of the VIRM.

The Materieel '64 prototype, Plan TT (Treinstel Toekomst, translation: 'Trainset Future') 501, was built by Werkspoor in 1961.

The Materieel '64 design is derived from the DMU Plan U, which had been built a few years prior.

Furthermore, the corner windows on the cabin at the head of the train were painted gray on Plan T and yellow on Plan V. Notable Materieel '64 innovations compared to older rolling stock included: Older train sets and carriages were later provided with central door lock and broadcasting system.

This brake system leads to a roughening of the running surface, making the tire rolling noise high.

In late 2015, Nederlandse Spoorwegen announced the withdrawal of the remaining Plan V sets in the 2016 timetable, starting in December 2015.

Since the beginning of timetable 2016, which started on December 13, 2015, the Nederlandse Spoorwegen planned to take all Materieel '64 trains out of service.
