Train delays have been caused by signalling problems today (Tuesday), with no trains currently running on a section of the line to London.

There have been delays of up to 60 minutes for trains travelling from Royston towards London Kings Cross due to a signalling problem between New Barnet and Alexandra Palace since around 6am.

Currently no trains are currently running between Finsbury Park and Stevenage due to the ongoing problem.

First Capital Connect has said replacement buses will run between Stevenage and London to all stations up to Potters Bar and Cockfosters, where passengers can get the London Underground.
