MOSCOW, Aug. 14 (UPI) -- Russian authorities plan to relax the secrecy surrounding the design of Moscow's subway system, which also doubles as a civil defense facility.
In an effort to attract foreign investors to modernize the aging public transportation system, the Moscow Transport and Road Infrastructure Department has vowed to ease the security surrounding designs.
"The participation of foreign contractors in subway development will require a qualitative change in the approach to designing and improving," said Tatiana Malashenkova, deputy head of the department. "Under existing norms, the metropolitan is both a means of transport and a civil defense facility and therefore, a considerable part of design documentation is secret."
Mayor Sergei Sobyanin announced routes would be extended by nearly 100 miles, which would require replacing some 4,000 subway cars on an ongoing basis. RIA Novosti reported foreign companies have already expressed interest, promising modern subway cars that are faster, quieter and more comfortable.
German engineering giant Siemens has already offered Moscow newer trains at low operating costs, Nezavisimaya Gazeta reported.
