Trains through Sandy, Biggleswade and Arlesey facing delays and cancellations due to blocked line

Trains running through Sandy, Biggleswade and Arlesey are facing delays or cancellations due to a signals fault.

And passengers are being advised to allow up to half an hour extra to complete their journey.

The problem has been caused by a fault with the signalling system between Peterborough and Hitchin - meaning the line towards St. Pancras International in London is blocked.

Disruption is expected to continue until around 5pm.
