Flooding and heavy rain has caused disruption across First Capital Connect’s (FCC) rail network.

The rail operator is being forced to deal with overhead powerlines problems, flooding and service disruption.

At present FCC is warning of delays between Hertford North and Stevenage, as well as the line between Stevanage and London King’s Cross.

This affects Welwyn Garden City, Hatfield, Welwyn North and Potters Bar stations.

There is flooding at the Potters Bar tunnel which is affecting one of the southbound lines, causing delays of up to 15 minutes.

An FCC spokesman said: “Our advice to passengers is to use alternative public transport including the Underground and local buses, or to take a fast train from Finsbury Park to Hatfield and catch a stopping service southbound.

“Train services running through these stations may be cancelled, delayed up to 15 minutes or revised at short notice.”

FCC’s website states: “Overhead wire problems between New Barnet and Alexandra Palace are causing delays of up to 15 minutes between Stevenage and London Kings Cross.

“Trains travelling from London Kings Cross towards Stevenage are unable to call at Alexandra Palace, New Southgate, Oakleigh Park and New Barnet.

“Passengers requiring these stations are advised to travel via Hadley Wood and catch a train heading towards London.

“Replacement road transport has been requested but there is no estimate for when these will available.

“First Capital Connect passengers may use London Underground and London buses on all reasonable routes.”
