Without Riyad El-Hassani's unimaginable bravery, a man could have lost his life.
Still shocked, Mr El-Hassani, 24, recounted to ITV News the moment he pulled former chairman of Eurotunnel, Sir Robert Malpas from the rails moments before a train powered into Marble Arch station.
"He had one of his hands on the electric rail. I just stopped thinking and ran and jumped.
"It was very close, it was a few inches. The train stopped about 5, 6 metres after us."
Sir Malpas, suffered a facial injury, but Mr El-Hassani's quick thinking prevented him from further harm.
