From Russian Transport Daily Report, 1 February 2010:

NATO Cargo Transit through Russia May Start within Days

Railway transit of non-lethal NATO freight through Russia and Central Asia to NATO forces in Afghanistan may start within days. This would seriously supplement transportation through the main transit route, which passes through Pakistan. Pakistan will most likely remain the main transit route for the foreseeable future. Cargo to be transported through Russia and Kazakhstan will not include weapons or ammunition. A transit deal with Russia signed in 2008 needed approval from Kazakhstan and other Central Asian countries to come into force.
