Thousands of rail users in North Herts were affected this morning by train delays on the line from Peterborough to London King’s Cross.

Great Norther Rail, which took over the franchise from First Capital Connect in October, said: “The issue this morning is with regards to infrastructure and not something we can control.

“A combination of signalling problems and a broken down train has backed the line up.

“Services are being delayed by up to 45 minutes or altered due to a signal and lineside problems at Alexandra Palace and a broken down train at Huntingdon.”

Great Northern’s official twitter feed posted: “There has been massive problems this morning. Not a great start to the week at all.”

UPDATE 12.15pm: Trains are running normally again between Peterborough and London.
