Интересно, во время шторма не заливает трамвайную линию?

This happened only once, in 1953.

However, there are regular heavy storms. Just for your information: in the last 4 days there have been 3 of them, each with 12 Beaufort, with wind speeds of 130 km/h.
Each time, the operation is suspended for the occasion. Depending on the circumstances, this can be a part of the line (especially the part in the photo), or the entire line (which happened last weekend), for a few hours or several days.

This depends on the damage (e.g. to overhead wires, fallen trees, etc.) and the clearance work.

The Ostend depot has an extremely large number of articulated buses, far more than are required on a daily basis for normal operation. This reserve is foreseen to be able to operate the coastal tram entirely with buses, which was necessary last weekend.

The biggest problem with storms by the sea is windblown sand and, of course, flying debris or falling trees. The sea is normally not the problem, unless there is an extreme coincidence of adverse conditions, as in 1953.
The dam is quite high and high enough to withstand heavy storms and spring tides.
