There was a record number of service interruptions last year in the metro.
The figure is said to be 1,171, lasting more than five minutes, and the jump over the year before is very big.
It's an increase of 25 per cent over 2016.
The orange line is the most affected followed by the green line.
Nearly half the interruptions are caused by commuters, either belongings falling on the tracks or people blocking the doors.
