Motorists are again being warned of slippery conditions on the Dutch roads on Wednesday and the KNMI weather bureau has issued a code yellow weather warning for the entire country, which will not expire until noon.

Gritting lorries have been out in force to combat black ice which has formed in places following Tuesday’s snow and the overnight frost. Snow residue on some roads is also causing problems.

Tailbacks during Tuesday’s evening rush hour stretched to a record 2,300 kilometres by 17.30 because of the snow, the ANWB motoring organisation said.  The problems were particularly acute around Eindhoven and Maastricht.

Rail services are back to normal on Wednesday but in Amsterdam, the city’s public transport company GVB says some tram services will be again disrupted because of continuing problems with the power supply.

Passengers can expect delays of up to 30 minutes on the 1, 2, 5, 7, 13, 17 and 24 services, the GVB said.
