Railroads in Russia are proving to be a far greater security challenge than airports; there are 18,000 train stations in Russia; the railroad operators have money to place passenger and luggage inspection facilities, radio jamming devices, and explosion-proof containers in 34 of these stations; train stations are not the only points where railroads are vulnerable to terrorist attack; a bomb can easily be planted anywhere along a train’s route; in 2010 alone, 542 instances of “objects placed on rails” were reported, as well as 101 cases of rail sabotage; some suggested fencing off the entire length of Russia’s railroad tracks — but since railroads in Russia stretch for over 82,000 kilometers, it was calculated that the funding needed for this comprehensive measure would be 13 trillion rubles; for comparison, the entire 2011 budget of the Russian Federation stands at 8.8 trillion rubles
