There were a series of stone throwing attacks against Sapsan trains. Possible reasons including cancelling of commuter trains, disruption of local transportation in rural areas, and accidents because of poor safety for pedestrians have been suggested.  New bridge crossings were built, platforms along the railway were reconstructed and additional track was completed in 2015. New Lastochka commuter trains were introduced on the Moscow – Tver  and St Petersburg – Bologoye routes. Local trains in the rural areas were saved.
