UPDATED 8.59AM A pedestrian has been killed after being struck by a train at the Glen Innes Train Station in Auckland this morning.

Police confirmed a person was hit at about 7am. The pedestrian - whose age and gender has not yet been released - was pronounced dead at the scene.

A woman told NZME she was standing on the platform when the incident happened.

As the train approached the railway crossing, they heard a horn beep twice before the driver pulled the brakes.

"There was a pedestrian walking across the rails as the lights were on. [The train driver] beeped and tried to stop. Our train is sitting on the crossing right now.''

The woman said although she could not clearly see the pedestrian at the time, she confirmed that the crossing's warning lights and bells were ringing as the train was it.

Emergency services - including police, fire and ambulance - arrived on the site quickly.

Officers escorted passengers off the train and onto the platform and commuters were asked to find alternative transport as the scene was cordoned off.

Trains are now running in both directions but with only limited services, and buses are running between Britomart and Sylvia Park to help with the load.
