Metro Transformation Work: changes to train services

How it will affect your journey plans

While we build this better transport network over the next few years, it may mean temporary periods of change to your journey plans. Where possible we are scheduling the transformation work to take place during less busy times to minimise disruption and offering connections between rail services and bus services.

Timetables are being updated weekly due to coronavirus, please check before you travel

You must wear a face covering on public transport and at stations, put it on before travelling unless you’re exempt. Please be respectful, not everyone can wear a face covering. For guidance visit

Follow any local travel guidance (currently in place in the boroughs of CaerphillyMerthyr and Rhondda Cynon Taff).
New local lockdown restrictions are in place affecting Caerphilly and Rhondda Cynon Taf council areas. The Welsh Government has tightened coronavirus laws across these areas to prevent the virus spreading .
