Line 2 of the Madrid Metro is a rapid transit line in Madrid. It runs through the city center between the Las Rosas and Cuatro Caminos stations, for a total of 20 stations (the Cuatro Caminos - La Elipa section with 60-metre platforms and the La Almudena - Las Rosas with 90-metre platforms), linked by 14.1 km of track in a narrow gauge tunnel, with a journey that lasts approximately 33 minutes. Despite being one of the oldest and shortest in the system, it has undergone various expansions throughout its existence. The first ended up as new lines (the Goya-Diego de León branch absorbed by line 4 and the Ventas-Ciudad Lineal extension absorbed by line 5) and the recent extensions to La Elipa and Las Rosas have taken the line to the eastern periphery of the city.
Most stations have side platforms, except Cuatro Caminos, which has a side platform and a central platform. The stations in the section between Quevedo and Santo Domingo, both included, are not adapted. The Banco de España, Retiro, Manuel Becerra and Ventas stations are also not accessible. Taking this into account, 60% of the stations on this line are accessible.
