Police are to question the engineer of a commuter train which crashed head-on into another, killing 18 people and injuring dozens of others, Belgian railway officials said today.
National Railways spokesman Jochen Goovaerts said the driver of the second train was one of those known to have died in the collision.
He said the engineer was badly injured.
Belgian police investigators will examine the black boxes of the two trains to try to determine whether mechanical failure, human error or weather conditions was primarily responsible for yesterday’s crash near a suburban station 9 miles (15km) south of Brussels.
Mr Goovaerts said the search of the wreckage for further victims was halted overnight and resumed this morning.
