The so-called "fast line" (50A) could no longer be used as a result, with trains being diverted. Delays reached up to 1.5 or even 2 hours this morning while other services were scrapped.

Thomas Baeken of the rail infrastructure company Infrabel said that "it is obvious that somebody tried to set fire to power supply cables to one of the signalling stations. (...) This is very serious, in the first place because this incident jeopardises the safety of rail staff and passengers." The Brussels judicial authorities started a criminal investigation.

It is not clear yet who could be responsible and why this happened. Baeken said that it is much too early to think of a possible link with the strike that was called off. There was also sabotage at earlier rail strikes recently.
