A TRACK worker killed by a train in London was on a zero-hours contract, had work fatigue and was exposed to danger when his colleague did not arrive, investigators found yesterday.

The unnamed man, who was 37, was hit by a Southern train on November 6 2018 near Purley, south London, after placing equipment on the track to protect the line.

The Rail Accident Investigation Branch (RAIB) said that the worker was probably fatigued, and that a second person who should have been working alongside him did not turn up that night.
