The woman was walking along the platform, pushing her child in a pram and looking up at the indicator board when she accidentally feel, according to British Transport Police (BTP).
Officers said she did not realise how close she was to the edge of the platform and accidentally pushed the buggy wheels over it.
She, the buggy and the child then fell onto the track, before the father jumped down to help them.
Police said that when they saw the oncoming train, all three were “extremely fortunate” as they were able move into a pit under the track.
The train then passed over the top of them.
A spokesman for the BTP said: “Amazingly none of them were seriously hurt, but as a precaution they were taken to hospital for check-ups.”
