‘Hero dad’ killed trying to save his twins from train tracks named

The father who died trying to save his twin girls after their pram rolled onto train tracks in Sydney has been named.

Anand Runwal, 40, died alongside one of the two-year-old twins, at Carlton Station near Kogarah in the city's south.

He rushed onto the tracks after the pram rolled as the couple got out of the lift on the platform yesterday.

The other twin had a miraculous survival.

She was taken to St George Hospital with her mother, Punam Runwal and have now been discharged.

The Indian community is said to be rallying around the family, who only moved to Australia last year.

Flowers and messages have been left at the station.

One message read "hero dad, angel baby,"

The family were captured on CCTV arriving at the station looking relaxed and happy just moments before the tragedy.

They got into the lift down to the platform at about 12.25pm on Sunday.

NSW Police Superintendent Paul Dunstan said it appeared the parents' hands came off the pram for "a short second" after they got out of the lift on the platform.

Dunstan said the father jumped onto the tracks to try to save his children in an "incredibly brave and heroic act".

But a train which was not stopping at the station went by, killing the father and one of the children.

Police arrived to the upsetting scene and rescued the other child.

Witnesses described what unfolded, with investigations underway.

"The father has jumped down to try and grab the children and the pram and as he's gone to lift it up onto the platform the train has just come," bystander Lauren Langelaar said.

"I was lying on the platform screaming out the husband's name. I could only hear one kid crying, not two."

A post from a school friend of Mr Runwal posted on Facebook about his death.

"Dear friends, it is with a heavy heart that I share the tragic news of the untimely passing of Anand Runwal ( From 1999 Batch) and his daughter," Sreyas Gopalakrishnan Thottarath said.

"Our deepest condolences go out to their family and loved ones during this incredibly difficult time."

NSW Premier Chris Minns, who lives nearby, called it a "terrible, terrible tragedy".
