Line 4 (Madrid Metro)

Line 4 is a rapid transit line of the Madrid Metro connecting the west and center of Madrid with the said city's northeastern end, running between Argüelles and Pinar de Chamartín. It consists of a total of 23 narrow-gauge stations with 60-metre platforms. Altogether, its route measures just under 15 kilometers , with a journey that lasts approximately 38 minutes. It is operated by a single train model, the 3000 series of the CAF company, which circulates in compositions of 4 cars. This represents a limitation on its maximum passenger capacity per train, which is compensated by one of the highest frequencies in the entire network.

Originally opened in March 1944, it was originally called the "Línea de los Bulevares" ("Boulevard Line"), with only 8 stations in its original version. Its expansion has occurred exclusively at one end, the eastern end, an atypical peculiarity in the Madrid suburban area. At first, this was produced by absorbing some stations on one of the branches of line 2. Subsequently, new sections were inaugurated as the capital expanded spatially, each incorporating a few stations. The inaugurations of sections in 1973, 1979 and 1998 stood out, making this line grow slowly and progressively. The last group of stations was inaugurated in 2007, more than 60 years after the line's genesis. This long period of time means that the most modern stations (more spacious, functional and accessible for people with reduced mobility) contrast clearly with the older ones (narrower, closed and rarely accessible).

The route of the line is not easy to describe precisely, except in the case of the most central stations. Broadly speaking, its oldest part was characterized by presenting a straight line layout without major technical complications (beyond some pronounced angles), acquiring a more complex and curvilinear shape towards the northeast. The inaugural section begins in the heart of Argüelles, runs along the Alberto Aguilera axis, crosses Paseo de la Castellana and continues along Calle de Goya. Subsequently, the extensions caused the line to run under Conde del Peñalver Street and, after some short windings, take the López de Hoyos axis, in the direction of Hortaleza. Once in this district, it draws its final curve, covering a good part of it, until it reaches Pinar de Chamartín. Thus, the line has stations in the districts of Moncloa-Aravaca, Chamberí, Centro, Salamanca, Chamartín, Ciudad Lineal and Hortaleza, all of which are located in tariff zone A.

History

Line 4 originally opened on 23 March 1944 between and Argüelles.

In 1958, the line took up a branch of what is now Line 2 from Goya to , which originally opened on 17 September 1932. In the 1970s, the line was extended in two stages: from Diego de León to in 1973, and later to in 1979.

On 1 April 1998, the line was extended from Esperanza to , allowing for a connection with the newly-opened Line 8. Later that year on 15 December, the line was extended to . On 11 April 2007, an extension further to the current terminus at opened. At this station, passengers can transfer to Line 1 as well as Metro Ligero Line 1 (ML-1). This station uses an island platform is for departures and a side platform for arrivals.
