Delays up to 30mins and cancellations on trains through Hertfordshire on Wednesday morning

Rail passengers face disruption on journeys from Hertfordshire to London Euston on Wednesday morning.

Damage to overhead power wires south of Watford Junction has forced London Northwestern to run a reduced service from Tring and the operator is warning other services could be delayed by up to 30 minutes.

Trains could be busier at Berkhamsted, Hemel Hempstead, Apsley and Kings Langley as a knock-on effect

A spokesman for Network Rail said: "There is disruption to and from Watford Junction due to a fault on the overhead electric wires near Kilburn.

"We anticipate this disruption will continue until noon on Wednesday (July 15). Replacement road transport has been requested to operate between Tring and Watford Junction to help with journeys.

"Please be aware that trains and stations may be busier than usual during times of disruption, please consider delaying your journey if you are unable to maintain a two-metre distance between yourself and other customers.

"You can check your journey using the National Rail Enquiries real-time journey planner."

Passengers are still being told to use public transport for essential journeys only and wear a face covering while on board.
