ProRail is currently working on doubling the track between Rijswijk and Delft. These activities also take place on the DSM Delft/Biotech Campus Delft site. This work is usually carried out at night when the trains are not running.
As from March 23 to 15 April 15, during certain nights so-called sheet piles will be put in place, excavation work will take place and a new track will be constructed. You can read all the details in the residents letter (available in Dutch only).
These activities could lead to some inconvenience. You can report any nuisance this via tel. 0800-7767245 (free number) or via www.prorail.nl/contact. On the website www.prorail.nl/rijswijk (website is in Dutch) you can read more about the project.
