There have been delays on train services between Stevenage and London stations this morning after a train broke down at Knebworth. Three trains had to be cancelled and others diverted from London Moorgate to King’s Cross.
Some services also had to start from alternative stations.
As of 10am there is still some minor disruption but most services have returned to normal.
