This is the official application of Rodalies de Catalunya. Download it and you will be able to find out about the train schedules (in real time and planned), the itinerary of your journeys and ticket prices and to check the network and train stations.
You can also check the accessibility of both stations and trains, as well as the way out of them. It also allows you to save your favourite stations and itineraries and to configure warnings about the service status.
The application is available in Catalan, Spanish and English.
