DSB has a fleet of 135 S trains. Each train has 2 driver's compartments, one at each end of the train. There is a lot of problems with noise from the side window in the driver's compartment, which are a nuisance for the driver. As the window opens down into an arched door, it drives down a rail structure that follows the rounding of the door. Due to wear and veil in existing construction, there is a lot of mechanical noise when the window is opened and closed. DSB wants to optimize the existing construction, so that:

- Noise is reduced

- Window opens and closes more muted (“soft close”)

- Wear on construction is reduced.

The solution should only include optimization of the existing design and thus does not include replacing a pane, driverboard changes, etc.

The change shall be carried out at the hands of the supplier, which has 4 driver room doors available at a time.
