Last week, there was a track failure at Seven Sisters at start of traffic, on the points coming out of the depot. The cause? Apparently in overnight maintenance, a bolt of the wrong size had been used and when the first train went over the track the block joint keeled over and failed. Result: major chaos on the Vic Line.
Wrong tools, poor maintenance, no staff on site to deal with the failure ... Anyone would think that Metronet cuts corners to maximise profit.
