also Bond villains, time to remake some old movies with 500kph underground train :D

this reminds me to the vacuum tunnel supersonic train concept

The thing is if something like the vacuum train were made for civilian use, it could easily hide miltary use. Who would know when it's all underground. Military trains running underground in a tunnel with civilian trains that bypass civilian train stations and deep enough to be nuclear bomb proof.

An evacuated tunnel costs per kilometer a large multiple of the cost per kilometer of a conventional high speed railway. But I would like a line from Shanghai to Taipei.

A fast train in a tunnel experiences a huge drag unless the train cross-section is small compared with the cross-section of the tunnel or, more practical, if the tunnel is evacuated. It has been proposed, many years ago already, that Switzerland would build a country-wide metro system with magnetically suspended trains running in evacuated tunnels at 1000 km/h.

hot dang! 1000kph? Now we are talking....

Any country whos military hides behind civilians should be treated with comptempt. Also such actions could invite the opposing participants to justify it as a target.

Does that include the Marine Base in Okinawa Island where the landing strip is right smack in the center of civilian dwellings? Remember it's not as wide and as big like Ft. Hood, TX and I don't believe the DPRK has any of those fancy smart bombs to avoid civilian casualties.

Well I did say "any country" Besides what came first, the landing strip or the surrounding dwellings? Its Sunday over here that means "a do nothing day" even a bit of simple research ;)

China has a great tradition of tunnel warfare. Her adept North Korea for example built incursion tunnels that have been detected by South Korea:

Even during Napoleon's days a tunnel for invading Britain was considered among other things:

The Swiss for example have a dual use of their mountain tunnels as civilian bunkers.

I think it possible that the Chinese military rethinks the construction of bunkers and turns them rather into a network of tunnels over a large area connected by fast railways to give them the safest interior lines possible for redeploying important assets without enemy knowledge. Such tunnels could provide safety against nuclear and bunker buster attacks if they are concealed enough. They aren't just one local complex. So you could build nuclear shelters at a much shallower depths(less expensive) than currently considered if you make them a more delocalised network. Any strong explosion that would kill a local bunker complex losses much of the energy in labyrinth of tunnels.

From an economic perspective there are some great settlement agglomerations in China that would profit from such fast underground connections and would pay off as much as the Swiss idea while dual use benefits the investing and developing military.

The British used the ocean liner QEII to transport troops during the Falklands war. I believe any nation, including the US, would use civilian transports when resources are stretched.
