The driver of a commuter train which collided with an intercity train in Amsterdam on Saturday, killing one woman, told eyewitnesses she may have missed a red light, according to media reports on Monday.

Volkskrant journalist Hein Janssen was sitting in the front compartment of the commuter train when the accident happened. He told the paper after the crash, the door of the engine cab opened and the driver got out saying ‘I am afraid I may have missed a red light’.
Transport minister Melanie Schultz told parliament in a briefing on Monday a missed red light appears to be the cause.
A spokesman for Dutch Rail (NS) had said on Saturday the two trains could only have been on the same track if one of them had driven through up a red light.
Track operator ProRail has not yet commented on the claims. An investigation into the crash, which injured dozens of people and led to 13 being hospitalised overnight, is continuing.
Train services west of Amsterdam were disrupted most of the weekend because of the crash but are now back to normal.
