Station Message

Beginning in at the end of March, we"Öll be undertaking an intensive 8-month programme of engineering work on the upper Rhymney line, from Caerphilly to Rhymney station, that will transform and electrify over 15km of railway line. These infrastructure improvements will enable electrified trains (Class 756s) to be introduced to the line, delivering faster, greener and more accessible transport to the communities of South Wales.

Planned Rail Closures & Engineering Works

To deliver this intensive 8-month programme of work safely, there will be periods where the railway line will be closed and rail replacement services in operation to keep passengers moving.

From March to October 2025, the railway line from Caerphilly to Rhymney will be closed on:

• Mondays to Thursdays, after 7pm, starting from 31 March 2025.
• For 6 weeks from Saturday 12 April to Friday 23 May, and from Saturday 19 July to Sunday 31 August.
• For 2 weeks from Saturday 18 October.
• Across several weekends (Saturday and Sundays) throughout this period

During periods where the railway line is closed, we"Öll replace each planned train with a bus service. These buses will travel from Rhymney/ Bargoed to Caerphilly (stopping at each station in between) and will connect with the train services from Caerphilly to Cardiff.

Mirroring the rail timetable, we"Öll operate a bus every 15 minutes between Caerphilly and Bargoed, and every 30 minutes between Bargoed and Rhymney.

From March to October 2025, we encourage all passengers travelling on the Rhymney line to check before you travel, due to the number of rail closures that will take place over this period.
