A BOMB alert brought trains to a halt for up to an hour between Sheffield and London.
The line was closed south of Bedford, after a suspicious package was delivered to the Bedfordshire and Luton Fire and Rescue Service Headquarters, near the tracks at Kempston.
No trains were allowed through for 35 minutes while the package was examined by Bedfordshire Police’s bomb squad.
A spokeswoman for operator East Midlands Trains said: “Services were held up on either side of the affected area, with delays of up to an hour, as there were several trains queuing up in each direction.
“Two trains had to be cancelled as a result of the incident but we worked hard to try to restore a near-normal service for the evening peak.”
Passengers heading from Sheffield to the capital were advised to use East Coast service via Doncaster, which use a different line into London, so were unaffected.
A Bedfordshire Police spokeswoman said the suspicious parcel was found to be safe and the railway, plus surrounding roads, were reopened.
The incident happened at 11.30am yesterday.
