Trains down on key Sydney lines after teen injured

A teenage boy is being treated for head injuries after an incident involving a Sydney train, with services cancelled on a key commuter line.

All trains between Sydenham and Redfern were cancelled on Tuesday morning, impacting the T3 Bankstown Line, T4 Eastern Suburbs & Illawarra Line and the South Coast Line.

The train chaos was triggered when police and paramedics rushed to the rail corridor near St Peters Station at around 5.45am to reports a teenager was injured.

The boy was travelling with a friend when he fell off the train and onto the tracks, his friend rushing to alert transport staff.

The teen was taken to Royal Prince Alfred Hospital in a serious condition.

By 7am trains were delayed by 40 minutes on the South Coast line and stopping at different stations on short notice, Sydney Trains warned. Commuters were urged to consider finding a different way to get to work on time.

The incident comes as a different teen faces a children’s court on Tuesday after police allege he parked a trailer across the rail tracks at Vineyard near Windsor last week.

A city bound train carrying 29 passengers hit the trailer on Thursday morning but the driver and all passengers were uninjured.

After inquiries by detectives police arrested a 16-year-old boy on Monday, hitting him with 13 charges including an act with intent to kill or injure people on the railway, possessing prohibited drugs, dealing with proceeds of a crime and stealing a motor vehicle.
