The station lies about two kilometers outside the regional hub of Bryansk, while the explosion that caused a train to derail and catch fire on Monday occurred near Unecha, closer to the Ukraine border.
Russian Railways put out a statement saying the train had derailed due to “the intervention of unauthorized persons in the work of rail transport”.
It did not mention an explosive device.
The state operator said the incident took place at 7:47 pm local time (1647 GMT) between Snezhetskaya and the nearby village of Belye Berega.
It said the train’s front locomotive and “around 20 wagons” were derailed and that rail traffic in that section had been suspended.
There have been many reports of sabotage on railways in Russia since Moscow launched its Ukraine offensive, but this week is the first time officials confirmed attacks on this scale.
