Major train services at Watford Junction have been cut again for nine days to enable railway upgrades.

Just last month, work was completed to the London Overground between Watford Junction and Euston and the Bakerloo line.

But Network Rail has now confirmed there will be another closure to the same 20-mile stretch between February 11 to February 19.

The scale of work will mean that the Bakerloo line between Queen’s Park and Harrow & Wealdstone and the London Overground between Euston and Watford Junction will be closed.

Affected stations include Watford Junction, Watford High Street, Bushey, Carpenders Park and Hatch End.

Upgrades last month saw 6,000 modern concrete sleepers installed, slight station makeovers, cable replacements and power supply improvements.

James Dean, Network Rail’s West Coast South route director, said: “We’re really grateful to passengers for their patience while we closed the railway just before Christmas so we could carry out these essential projects.

“It enabled us to bring sections of track right into the 21st century with new equipment which is much more reliable and robust."

He added: “Next month we’ll be returning to carry out even more work to improve the Bakerloo line and London Overground for the future.”
