A man died after being hit by a train at Hassocks this afternoon (Monday 7 April).
Commuters returning home to Brighton and Hove suffered severe delays well into the evening.
The person was struck by the 1.34pm First Capital Connect Thameslink train from Brighton to Bedford.
The British Transport Police said: “Just after 2pm today we received reports of a person having been struck by a train at Hassocks station.

“The death is not currently being treated as suspicious and officers are currently working to formally identify the deceased.
“Following the formal identification we will assist in the preparation of a report for the coroner.”
Later in the evening a teenage boy was electrocuted after he accidentally fell on to the track at Horley.
