A tragic accident at Carlton Railway Station in Sydney resulted in the deaths of a 40-year-old man and one of his two-year-old daughters.

The incident occurred when a pram carrying two young girls rolled onto the train tracks and was struck by an oncoming train.

The father heroically jumped onto the tracks in an attempt to save his daughters but was unable to rescue them.

Premier Chris Minns praised the father's actions as an instinctive act of bravery.

The parents momentarily lost control of the pram, leading to the accident.

The train involved was not scheduled to stop at Carlton but had slowed down as it passed through the station.

Authorities have urged the public to avoid the area as investigations continue, with train services on the T4 line disrupted for a few hours.

This incident adds to a series of recent train-related tragedies in Sydney, underscoring the need for vigilance and caution around railway stations.
