The R1 is a line of Rodalies de Catalunya's Barcelona commuter rail service, operated by Renfe Operadora. It runs northwards from the Barcelona area to the southern limits of the province of Girona, passing through the coastal Maresme region. Since 2014, some services have been extended further north towards Portbou, near the French border. These services are designated RG1 and are considered part of the Girona commuter rail service. According to 2008 data, the line's annual ridership is 39.6 million, the highest on any line of the Barcelona commuter rail service, with an average weekday ridership of 102,214.〔 R1–RG1 trains primarily run on the Barcelona–Mataró–Maçanet-Massanes railway, the first railway line in the Iberian Peninsula. They use the Meridiana Tunnel in Barcelona, where they share tracks with Rodalies de Catalunya's Barcelona commuter rail service lines and , as well as regional rail line , calling at Sants, Plaça de Catalunya and Arc de Triomf stations. R1 services use as their southernmost terminus, and as their northernmmost one. On the other hand, no RG1 services run south of , or north of . Together with lines , R3 and R4, the R1 (then simply numbered line 1) started services in 1989 as one of the first lines of the Cercanías commuter rail system for Barcelona, known as Rodalies Barcelona. Originally, R1 services had two southern termini, L'Hospitalet de Llobregat and Barcelona–El Prat Airport stations. In 2005, all trains terminating at the airport moved their southern terminus to Molins de Rei. In the long-term future, it is projected that the R1 will take over the southern section of line R2, creating a major north–south axis that will extend along the coast of the Barcelona metropolitan area. ==Infrastructure== Like the rest of Rodalies de Catalunya lines, the R1–RG1 runs on the Iberian gauge mainline railway system, which is owned by Adif, an agency of the Spanish government. All of the railway lines carrying Rodalies de Catalunya services are electrified at 3,000 volts (V) direct current (DC) using overhead lines. The R1–RG1 operates on a total line length of ,〔 which is entirely double-track, excepting for the single-track section between and stations. The trains on the line call at up to 48 stations, using the following railway lines, in order from south to north: The entire length of the Barcelona–Mataró–Maçanet-Massanes railway is solely used by the R1–RG1,〔 though the rest of the infrastructure it uses is shared with other services. South of , it shares tracks with Rodalies de Catalunya's Barcelona commuter rail service line . Between L'Hospitalet de Llobregat and Arc de Triomf stations, R1 and RG1 trains share tracks with commuter rail lines and , and regional rail line , using the Meridiana Tunnel through central Barcelona. After Arc de Triomf, they branch off to El Clot-Aragó railway station, running on exclusive tracks from this point on to Maçanet-Massanes. North of Maçanet-Massanes, the R1–RG1 shares tracks with regional line and freight services. In May 2015, Adif announced that the R1–RG1 would be the first Rodalies de Catalunya line to feature the European Rail Traffic Management System (ERTMS) signaling and security system. ERTMS Level 2 will be installed on the section between L'Hospitalet de Llobregat and Mataró, increasing capacity and reliability parameters. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「R1–RG1 (Rodalies de Catalunya)」の詳細全文を読む スポンサード リンク
