Several hundred people were safely evacuated...
"Some 600 passengers were evacuated after smoke was reported in one of the train cars in the tunnel between the Semyonovskaya and Elektrozavodskaya stations," Yevgeny Bobylyov said, adding that no one was injured.
The smoke reportedly appeared because an electric cable caught fire, which has by now been extinguished.
