NS has shortlist four manufacturers to supply a new fleet of intercity EMUs.
Alstom, Bombardier, Siemens and Stadler have moved through to the final stage of bidding for a contract to build a new generation of 200 km/h intercity trains.
The new trains are expected to start going into service from 2021.
The tender for new long-distance train sets followed the collapse of the V250 project.
As well as new trains, NS is extensively modernising its existing fleet. First generation VIRM double-deck cars are currently being overhauled and will soon return to traffic.
