Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Metrosur is a 40Km tunnel. The Line 10 extension is above ground.

Since then, more above-ground sections have been build at the end of various lines, as well as three light-rail (tram) branches.

Metro Madrid added more than 40 km (25 mi) in a four-year period to 2003, and another 56 km (35 mi) heavy metro this year -- to a total of 283 km (176 mi) -- note that Madrid is a city of just 3.2 million. The showcase project of the previous four years was Line 12 (yellowish green on the map), nicknamed MetroSur. This ring line doesn't circle the city, but serves a couple of suburban towns by distributing traffic from radial subway and rapid transit lines. Planning, tendering, boring, fitting out with concrete lining and tracks and electronics of this 40.5 km all-tunnel line; station construction; and purchase, testing and commissioning of subway trains was all done within four years and on a budget of only €1.1 billion! On time and budget in the extreme! Compare that to the time and cost earmarked for New York's 8.5-mile Second Avenue Subway project.
