>Barcelona’s Line 9 (pdf), currently under construction, is a very interesting for many reasons:

>It will be the longest metro line in Europe, with 48 km in total
>The metro line will be completely automated
>The construction is based on the idea of a single 12-metre wide tunnel, large enough to hold 2 tracks (plus platform) on two levels
>The stations are nearly completely enclosed inside the envelope of the tunnel
>Despite the high complexity of the line, the overall cost is quite reasonable

>The metro line is almost completely contained in this single tunnel, which is wide enough to host other infrastructure: extra tracks to park trains at night, ramps to connect between the two directions, and facilities for egress and other equipment.
