Transport authorities are inter-administrative voluntary corporations responsible for coordinating the public transportation system. There are currently four transport authorities in Catalonia:
Tarragona - Reus(service suspended due to Covid pandemic and not reactivated yet as of May 2023. The route is covered by Regional Exprés' lines R14 and R15)
Salou- PortAventura - Tarragona - L'Arboç (service suspended due to Covid pandemic and not reactivated yet as of may 2023. The route is covered by Barcelona's R4 from L'Arboç to Sant Vicenç de Calders and by Regional Exprés' R17 from there to Salou)
The Generalitat de Catalunya is building a tramway system connecting several cities of the Camp de Tarragona, those being Reus, Tarragona, Vila-seca, Cambrils and Salou. This service, the Tramvia del Camp de Tarragona (also called TramCamp) will comprise around 46km of tracks and 47 stations, with a first part of 14km (between Cambrils, Salou and Vila-seca) being finished in 2026 and the Vila-seca - Tarragona and Vila-seca - Reus sections finishing in no longer than 10 years from the initial announcement in 2023. The whole system will be built in Standard-gauge railway and operated by Ferrocarrils de la Generalitat de Catalunya.

Most of Catalan's railway gauge is broad gauge, as in other parts of Spain, and new railways are built in standard gauge to be able to connect with European railways; therefore, some stations exist where trains can change gauges. Currently, there are only two stations in Catalonia with that capability:
Nowadays there are 32 comarcas (group of municipalities) with some kind of rail service; 14 of those have Rodalies Barcelona and/or FGC services. There are comarcas with medium- or long-distance stations and nine comarcas without rail service.
