“What we have to realize is that train traffic below continues as usual,” he continues. This means that the workspace does not extend further than the width of the underground platform. “By properly preparing everything and shielding it from travelers, you can see that we still make it possible to carry out these activities within a very small space.”
Underground – during major maintenance of the Schiphol tunnel – the logistical challenges are even greater. Building materials must be supplied and removed via the kilometre-long tunnel. Construction manager at ProRail Marijke de Zwart explains: “We have two pipes and we are renewing them one by one.” This means that work can always be done safely in one tunnel tube.
Fewer train cancellations in the future
This now means that fewer trains are running, but should actually prevent train cancellations in the future. “We are making some adjustments: previously we had the track on a small block and now on a larger beam, so that it is attached to the structure and is less susceptible to interference.”
But more is being done to make it easier for travelers in the future. The track is raised, so that the step to the platform disappears. “When you arrive with your suitcase, you can roll onto the platform and go to your flight.”
The work on the bus station must be completed in 2027, and ProRail will be ready with the Schiphol tunnel in 2028.
