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

Please don’t forget, our trains are currently for key workers and essential travel only. Find out more here

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