Overhead power cables had frozen solid at Halle outside Brussels leading to power problems for the trains. Several tracks had to be taken out of service for a while.

The problems have meanwhile been sorted, but are having a knock on effect causing delays to later services. At its worst Thalys services were delayed by 2 1/2 hours.

Eurostar services were held up for 2 hours.

Rail track company Infrabel believes the problems will persist until the early afternoon.

Domestic traffic remained unaffected by the problems.
