Trains are set to be heavily delayed through rush hour after a failure at Watford Junction.

National Rail has confirmed that disruption to services through the town’s main station is expected to continue until 7pm today (June 26) following a raft of cancellations.

“A points failure at Watford Junction means some lines are disrupted,” a service alteration update said.

“As a result, trains through this station may be cancelled, delayed by up to 30 minutes, or revised.”

Avanti West Coast and London Northwestern Railway are listed as the routes affected.

According to live departure boards, every train through the station between 4.30pm and 4.45pm has been delayed, including one cancelled service.

The 4.54pm service to Tring as well as the 5.32pm and 5.52pm trains to London Euston have also already been cancelled due to the points failure.

Several other services are expected to be delayed.

“You may be entitled to compensation if you experience a delay in completing your journey today,” National Rail added.

“Please keep your train ticket and make a note of your journey, as both will be required to support any claim.”
