UPDATED 5.22pm Emergency services have managed to get the sole female occupant out of a vehicle which collided with a train earlier this afternoon in Morningside Drive.

She is being transported to Auckland Hospital in a serious condition.

A Herald reporter at the scene said it appeared the car had been sitting on the tracks in an area marked by yellow lines when the train hit it "dead centre" on Morningside Drive.

The blue hatchback then spun off the tracks and its airbags deployed, she said.

Police said early information from the scene was that the barrier arm was down and the lights were flashing when the vehicle has driven through.

All trains have been stopped and road closures were being put in place.

Diversions will be put in place and motorists are asked to avoid the area.

Two fire trucks, police cars and an ambulance were at the scene, which had now been cordoned off.

Fire said a woman was stuck in the car and had suffered serious injuries in the crash.

Crews were working to free her from the car at 4.38pm.

The Herald's reporter said the woman appeared to have been removed from the car by 4.48pm.

Auckland Transport said train passengers should expect cancellations and delays on the Western line due to an emergency services incident at Morningside.

An eye witness on the train told the Herald he could see fire crews using the jaws of life to try and remove the woman from the car.

He said no one was allowed off the train, which had been on its way to Swanson from Britomart.

The serious crash unit is attending and is expected to be there for sometime.
