Hundreds of passengers were stranded last night as a man’s body was found in a railway tunnel in Lincolnshire.

Passengers were stuck on trains as services on the East Coast Main Line were suspended from 9pm on Sunday to 1.49am on Monday, after a man’s body was found in Stoke Tunnel near Grantham.

The incident affected seven northbound and six southbound trains carrying around 1,800 people.

The man’s identity and cause of his death are not yet known.

A spokesman for the British Transport Police said: “The incident is currently being treated as unexplained. A file will be prepared for the coroner.

The train involved has yet to be established and inquiries are ongoing.”

Insp Chris Fellows of BTP explained why the line took so long to reopen. “Because the death is unexplained it is treated in a different way from a non-suspicious death.

“As we don’t have an immediate explanation certain things have to be done, such as forensic examination of the site, before we can remove the body and reopen the line.”

An East Coast spokesman said: “It’s frustrating for our customers. In this situation we are entirely in the hands of BTP.”
