At the station "Ploshchad Lenina" in the St. Petersburg Metro after the announcement of "Sliding Doors!" the train drove off with the opened doors. This was recorded on video by a passenger of wagon, who later showed it on YouTube.

There were not many people in the train, since the incident occurred in the evening. At the next station the passengers told the engineer about the fault. It turned out that  automatic in the train stopped working, so a driver didn’t notice that the door is not closed.
