Holidaymakers are being warned that Amsterdam’s Schiphol airport will be difficult to reach by train this weekend because of essential work on the tracks.

Trains will only operate on the Leiden to Schiphol route, a spokesman for track operator ProRail told Nos television. Buses will take passengers who have to catch a plane from Amsterdam’s Sloterdijk and Zuid stations.

The work coincides with the start of the school holidays in northern parts of the country, meaning it will be extra busy at the airport. This weekend’s work is part of plans to expand the railway alongside the A4 motorway from two tracks to four.
