Ellie Burrows, Network Rail’s managing director for the southern region, said the incident which killed Mr Byrne “should never have happened on our railway”, and the company is “deeply sorry for what happened”.
Richard Hines, ORR’s HM Chief Inspector of Railways, said: “Our industry’s track workers play a crucial role in delivering a safe railway for passengers and users of the system, often working in challenging and difficult conditions.
Tyler Byrne, 30, from Aldershot, Hampshire, was working on tracks for Network Rail in Surbiton in February 2021 when he was struck and killed by a train travelling at around 76mph.
Earlier this month, Network Rail was fined £3.75 million after two workers were struck and killed by a train at Margam, near Port Talbot in July 2019.
The ORR, which launched the prosecution, said Network Rail pleaded guilty to an offence under workplace health and safety legislation.
