On Sunday, no trains will run between Rotterdam Centraal, Leiden Centraal, and Schiphol Airport. Rail operator ProRail will then carry out extensive work on the tracks near these stations, NS reported. The Intercity Direct between Amsterdam and Rotterdam will also not be running. However, there is an alternative route between Rotterdam and Schiphol, but passengers will have to change trains several times and also use the metro network. The travel time will then increase to one and a half hours, NS warns. The carrier therefore advises travelers to look for alternatives.
