The firefighting facilities at the Rotterdam harbour rail yards must be adapted by 1 January 2023. This is due to the stricter requirements of the Environmental Permit. In order to comply with the applicable regulations, the Botlek, Europoort, Maasvlakte West, Pernis, and Waalhaven Zuid marshalling yards need to have more and wider emergency roads. Additionally, the existing dry fire mains need to be replaced with wet mains. This is a task that ProRail cannot accomplish alone.
