Passengers travelling to and from Cardiff this coming weekend are being advised to check their journey plans in advance, as essential overnight engineering works will cause disruption between 19–21 July.

Network Rail will be carrying out critical upgrades between Cardiff Central and Newport, designed to improve the safety and reliability of the railway. The maintenance will involve renewing rails, sleepers and track stone, as well as servicing switches and crossings, which are key to directing trains between tracks.

To carry out the work safely, the section of line will be closed overnight from 1am on Sunday 20 July until 2:30am on Monday 21 July, resulting in several service amendments and replacement buses.
