These locomotives are used with NS DD-AR double-decker coaches in a push-pull setup and treated as an EMU.

The couplers, from BSI (Bergische Stahl Industrie, Germany), allow a mechanical, pneumatic and electrical connection between two DD-AR sets.

Several of these coaches have been rebuilt with a drivers cab, allowing the loco to be remotely controlled.

Number 1735 has been scrapped, due to a devastating fire, which occurred on 24 February 2000 in Venlo.

Some locomotives carry names of towns and cities in the Netherlands, the table underneath shows which engines.
