Preliminary findings into the cause of the LRT collision in the underground tunnel between the KLCC and Kampung Baru stations last night revealed an element of "negligence" by the driver in manually controlling one of the trains, according to Transport Minister Wee Ka Siong.

Wee said findings by the Land Public Transport Agency found that the empty train 'TR40' was moving in the wrong direction and collided with 'TR81' on the same track.
