Is This the London Tube Train of the Future?

Siemens unveiled this concept for consideration for the next generation of tube trains. The current rolling stock is undergoing an upgrade now. And as The Londonist points out, aside from the distinctive circular operators cab, this vision isn't all that different from the newer cars.

Siemens does point out this concept design would increase capacity by 11 percent, impressive, considering one of the limitations of London's system are the tight tunnels, which constrict car height, Many of the the system's eponymous tubes were originally designed and built well over 100 years ago.
