Between Machynlleth and Pwllheli

Description

Engineering work is taking place between Dovey Junction and Pwllheli, closing all lines. Background information on the work can be found below.

Rail replacement buses will operate between Machynlleth and Pwllheli.

Trains will run as normal between Birmingham International / Machynlleth and Aberystwyth.

Background information:

During the line closure, as part of ongoing investment on the Cambrian Coast Line, Network Rail engineers will install new track between Pwllheli and Dovey Junction.

The track renewal involves replacing key components of the railway, including rails, sleepers, switches and crossings, and sets of points. These are critical to ensuring trains can run safely and reliably and help reduce future disruption caused by faults or speed restrictions. Engineers will also be carrying out vital maintenance on the railway and level crossings along the route, as well as inspections of bridges, helping to ensure the long-term safety and resilience of the railway.

More details on this project are available on the Network Rail website.
