Passengers are being advised of essential engineering work taking place on the North Wales railway between Chester and Llandudno Junction from the early hours of Saturday 6 June and reopening in the early hours of Monday 8 June.

29 May 2026

During this time, the railway will be closed to allow teams uninterrupted access to carry out important maintenance and upgrade work as part of continued Network North Wales upgrade and the recent introduction of a new timetable,

Transport for Wales is working with its industry partners, Network Rail on a range of improvements over a selection of areas, including:

Flint – Drainage improvements to help reduce the risk of flooding and improve the long-term resilience of the railway
Pensarn – Foundation and site preparation work ahead of the installation of a new accessible footbridge
Rhyl (Saturday night only) – Sleeper replacements to maintain track quality and support smoother, more reliable journeys for passengers

During this time, passengers should expect:

No rail services will run between Chester and Llandudno Junction during the closure
Replacement transport will be in place to keep passengers moving

These improvements form part of continued investment in the North Wales railway and are essential to:

Maintain reliability following the recent timetable uplift, allowing passengers to take advantage of 50% additional train services
Support future accessibility improvements for passengers
Keep the railway safe and resilient for staff, passengers and freight services

Colin Lea, Planning and Performance Director at Transport for Wales said: "We’re encouraging all passengers travelling between Llandudno Junction and Chester to check before they travel over the weekend. As no trains will run between these destinations, our Manchester Airport, Cardiff Central, and Liverpool Lime Street services will start and terminate at Chester, while services from Holyhead will terminate at Llandudno Junction

"We’ll be running rail replacement services between Llandudno Junction and Chester roughly every half an hour on the Saturday, and every hour on the Sunday. We’ll also have ticket acceptance in place with Arriva Bus. Please allow extra time for your journey and check before you travel using our website or app”.
