An alarm accidentally set off by a power surge caused a train to stop suddenly, the Associated Press reports, sending several cars off the rails. The incident happened near Park Pobedy, the deepest station in Moscow's subway system, making evacuations particularly difficult.
According to Russian Emergency Situations Minister Vladimir Puchkov, terrorism has been ruled out as a potential cause.
"There was smoke and we were trapped inside," a passenger told local TV station Rossiya 24. "It's a miracle we got out. I thought it was the end."
