balasto,

How many lanes across are the two M-30 tunnels? And is that a lower level for emergency vehicles?

Three 3,5 m-wide lanes per tunnel. And yes, they will have a lower level for emergency vehicles. See this post by Carretero: http://www.skyscrapercity.com/showpo...&postcount=447

Please note that the two south by-pass tunnels do not replace the current surface strech (3-4 lanes per direction) but they will be a suplement to it.

Truly amazing! In the Bay Area, the transit authorities are talking of dumping $1.4 billion underground just for a puny 2-mile light rail subway extension to Chinatown & somewhere in the $12-15 billion range to extend BART another 15 miles or so down to San Jose. Even still, given the huge costs & funding shortfalls, it's doubtful if either will happen anytime soon, if ever. Regardless of whatever differences may exist in environmental regulations, property & real estate rights, & NIMBYism, we really need to study the success of Madrid's remarkably cost-effective Metro building binge, borrow what we can from it, & if possible, bring some of their construction teams over. Madrid's overall level of metro expansion also must be near tops in the developed world.

Just ignore that post. It has nothing to do with engineering.

BTW about safety.. is Madrid a safe place to be? How would you estmiate? Would you feel safe walking in the evening in the downtown/some other areas/ taking a metro?
When i was there i felt relatively safe but i didnt move further than atocha-charmartin-palaco royal area....

Madrid is as safe as any other city of its size in Europe. You have to be aware of pickpockets when it's crowded, specially in the places you mention. Metro is safe at almost any time. You may find a fight late night at weekends, but I have just found one in more than 30 years I live here.

I don't have the numbers, but I think crime rate in terms of tourist thieving has been decreasing in the last years.

Going back to Metro, two extensions and a new station in a built line have been opened in the last weeks, and there is an opening schedule for the different extensions and stations in the next four months.

Just comparing Metro construction costs..

LA and Toronto: $200 million/km

Madrid: $55 million/km

New Delhi: $30 million/km (65km for $2 billion, already constructed)
$35 million/km (55km for $2 billion, to begin construction)

Mumbai: $35 million/km (146km for $5 billion, to begin construction)

Bangalore: $35 million/km (33km for $1.2 billion, to begin construction)

If building a metro in Spain is only about 60% more expensive than building one in India despite the higher costs in Spain, it is quite remarkable

London may not be any San Fransisco but it sure isn't flat... Trust me, I cycle.

Anyway, Hurrah to Madrid for a phenominal bit of work... Much as I love London 4 Billion Euros wouldn't get you anything like as much...

I believe in Moscow it is around 50 mil/km.

Unfortunately they are not building in Moscow as much as in Madrid these days.

Ok, this means Moscow will stay the number two in Europe after London.

Regardless where they got the money, Madrid has done a very impressive job with their metro.

The new stations might not win architecture awards, but they are simple, clean, and practical. I have seen some underground stations that at the time were edgy and impressive to the architectural standards of the time, but that now look awfully anachronistic. Yet, simple and practical is always a good fit.

Amazing expansion by any means. Spain is doing extremely well in every economical sector the last decade.

Still, the most impressive factor is the low cost. How is this possible!
For comparison reasons do you have figures about Barcelona Subway?
Are they similar?
