Delays on London Midland trains
Commuters are warned to expect delays on the London Midland route between London Euston and Northampton.
Signalling problems at Ledburn Junction, south of Leighton Buzzard, are currently affecting northbound services.
There may also be congestion as ‘fast’ line services may cross over to the slower line north of Hemel Hempstead.
Delays of around 15 minutes are predicted.
