Príncipe Pío platform

What you didn't know about Line 6

It has the deepest station in the network and even a museum on its premises.

Line 6 starts a profound transformation to become Metro de Madrid's first automated line. What better time than now to discover its most surprising fun facts?

You may not know this, but this line connects to all the other lines in the network, except for MetroSur. In addition, some of its stations are the most used by our users, such as Moncloa, Príncipe Pío, Nuevos Ministerios and Avenida de América. Among all of them, there is a particularly interesting one, Cuatro Caminos, which, located 49 metres below the surface, is the deepest in the network. 

Line 6 is very artful. There are a large number of murals decorating its corridors and platforms, such as those by Eladio García de Santibáñez in the stations of Laguna, Conde de Casal or Méndez Álvaro or those by Alfaraz in República Argentina and Nuevos Ministerios.  On the other hand, Arganzuela - Planetario has a sphere in the likeness of a celestial body with a diameter of 5 metres. 

If you get off at Pacífico station, you can visit Metro's Nave de Motores, where you will find three large engines, similar to those of the Titanic, which supplied energy to the Madrid underground until the 1960s. And without even going outside, at Carpetana station, Metro has its own underground museum, where you can find palaeontological remains from the Miocene.
