A number of train services travelling through Cardiff will be cancelled or diverted over the weekend
A key Cardiff train station will be closed for several days while National Rail staff carry out engineering works.
There will be no trains to or from Cardiff Queen Street from Saturday, July 25, to Monday, July 27.
The work means a number of services which would normally travel through the train station will be affected with many journeys being cancelled over the weekend and others operating on different routes to normal.
Ahead of the disruption Transport for Wales has urged passengers to check whether their route is disrupted and plan their journey ahead of travelling. Never miss a Cardiff story by signing up to our daily newsletter here.
