A rail firm has been fined £1m after a man died when he leant out of an unlocked train window.
Simon Brown, 24, from East Grinstead, West Sussex, was killed when he hit his head on a steel gantry on the side of the track while on the Gatwick Express in London in August 2016.
In May, train company Govia Thameslink Railway pleaded guilty to a health and safety breach.
Along with the fine, the firm was ordered to pay £52,267 in costs.
Mr Brown had been previously described by friends as a life-long railway fanatic who was working in the rail industry.
He first volunteered on the Bluebell steam railway in Sussex aged nine and was working as an engineering technician with Hitachi Rail Europe in Bristol.
The accident happened at Wandsworth Common station as the train was travelling to London Victoria from Gatwick Airport.
The train was travelling at 61mph when Mr Brown suffered the fatal injuries.
A report by the Rail Accident Investigation Branch said there had been a sticker on the door warning passengers not to lean out of the window, but it was “cluttered” with other signs.
Govia Thameslink said it had taken the health and safety failings very seriously and pleaded guilty at the earliest opportunity.
