A mother pushing her two-year-old daughter in a buggy onto a waiting train was crushed twice by its closing automatic doors.

Zoe Swift, of Hirstwood Crescent, Saltaire, said she feared for the safety of daughter Jessica, two, who only escaped being trapped between the heavy doors herself because her mum twice stood in the way.

The pair had been set for a shopping trip to Bradford when the train door shut on Mrs Swift as she and Jessica were boarding the train at Saltaire station.

Screaming for help, she started to get her daughter onto the train.

However, the doors again slammed shut a second time - into her back - as she moved to protect Jessica.

Mrs Swift, 30, said she was "lucky" to have escaped with painful bruising to her shoulder, arm, back and hip following the accident on Monday.

But the married mother-of-one said the accident could have been much worse.

And she is now calling for answers from rail company Northern Rail asking why the accident happened.

She said: "I am really angry about this. It could have seriously injured Jessica, if not killed her.

"If the buggy had been the other way round, it could have caught Jessica's leg.

"As it was, it really hurt me and bent the buggy.

"People need to be aware that they can easily get trapped in train doors and be injured."

It is the second time this year that Jessica has had a close escape because of closing train doors. About two months ago Jessica was with her grandmother, Margaret Swift, aunt Candice Swift and her two-month-old cousin, Abigail Swift, when the doors closed on the baby's pram.

Zoe Swift said: "It doesn't bear thinking about what could have happened to them.

"This just shows it is not the first time this has happened, so they can't say it's a one-off."

Mrs Swift said she was now "too scared to go back on a train" after the traumatic incident.

In her letter to Northern Rail, she said: "As we sat on the train, it pulled into Shipley, and then Frizinghall before the conductor came to see how we were. I would like to know exactly what you are going to do to prevent this from happening again."

Clare Conlin, of Northern Rail, said: "We are sorry for any distress caused to Mrs Swift and her daughter.

"Our customer relations department has received Mrs Swift's complaint and an investigation is underway.

"Safety is the primary concern for our conductors and they are regularly monitored in their observance of door procedures.

"We also hold regular briefings and periodic competency assessments on correct door procedures."
