Major delays on Auckland train network after body found on track at Papatoetoe station

Trains have been seriously disrupted on Auckland's southern and eastern train lines after a body was found on the tracks at Papatoetoe Station.

A train driver reported seeing the body at 7:30am Wednesday morning. Four hours later, some trains are still delayed.

For several hours, southern and eastern line passengers had their journeys disrupted, and people who intended to travel on a train through Papatoetoe had to take replacement bus services.

Would-be passengers tweeted complaints of a lack of rail replacement bus services and reported hundreds of people waiting at replacement bus stops.

The sudden halt to services lead to confusion at stations up and down the eastern and southern line, with one person tweeting he was one of 100 people waiting for a train at Manukau Station and "no one knows what's going on, not even staff. No extra buses?"

Grant Pritchard tweeted an image of hordes of people waiting for a bus in Otahuhu, saying none of the buses were stopping for them. "Total chaos," he said.

Police are investigating.
