Barcelona Metro line 4
Line 4, often known as "Línia Groga" (Yellow line), is a rapid transit line of the Barcelona Metro network, operated by TMB and part of the ATM fare-integrated transport network.
Originally opened in 1973, Line 4's route follows an incomplete loop pattern, linking the heart of Barcelona to the districts of Horta-Guinardó and Nou Barris on one side and the neighborhoods of la Barceloneta and Poblenou on the other. Works are currently in progress to extend the line to the future Sagrera railway station and to La Sagrera rapid transit hub.
Line 4 is a fully underground 16.7 km (10.4 mi) long route with 22 stations. As other lines in the Barcelona Metro network, the line runs on 1,435 mm standard-gauge track and overhead wire electrification. Its current termini are Trinitat Nova, which is an interchange station with Line 3 and Line 11 and La Pau, which is an interchange station with Line 2.
The line runs from la Trinitat Nova, in the Nou Barris district, to La Verneda i la Pau in the district of Sant Martí. Along its route, Line 4 crosses the districts of Horta-Guinardó and Eixample, serving the centre of Barcelona at Passeig de Gràcia and Plaça d'Urquinaona. The line then serves Barcelona's waterfront at la Barceloneta before crossing Poblenou and other neighborhoods in the district of Sant Martí.
Line 4 was used by 61 million passengers in 2024, making it the fourth most used Barcelona Metro line among those managed by TMB.
Initially called Line IV (Roman numerals were used on the network at the time), it was originally conceived as a loop line in the 1966 Barcelona Metro plan. In 1971, the project was modified to follow its final alignment.
The line would start operations in 1973, with the initial route taking over part of the original Gran Metropolitano de Barcelona (most of the original route would become part of Line 3). Specifically, the branch from Aragón (nowadays Passeig de Gràcia) to Correos, which had been closed down in 1972, was split from the main branch and combined with a new extension to Joanic to form the initial Line IV route. Correos would be closed permanently to allow for future extensions, with Jaume I becoming the initial terminus of the line. Thus, Urquinaona and Jaume I, which opened in 1926, were the two original Gran Metro stations that became part of Line 4.
The line's first expansion opened in 1974, with a 2 station extension from Joanic to Guinardó. It was extended further to Barceloneta in 1976 and to Selva de Mar in 1977. The line would be extended on both ends in 1982, from Guinardó to Via Júlia and from Selva de Mar to La Pau. That same year, in the context of a general reorganization of the Barcelona Metro, several stations changed names and Line IV became Line 4.
