'Nobody should go to work and not come home'
"Nobody should go to work and not come home," says Adrian Grant, whose father-in-law died after being hit by a train while working on a railway line in 2019.
Gareth Delbridge, 64, and his colleague Michael "Spike" Lewis, 58, were hit by a Great Western Railway train travelling from Swansea to London Paddington while working on the line at Margam, Neath Port Talbot.
Network Rail was fined £3.75m over the deaths last week, and said it was continuing to transform the safety of its workforce.
Mr Grant said there is still much more to be done and the amount paid would never be enough as "you cannot put a value on life".
