You don't see this on the 6.15am from Brighton to Waterloo - a large brown bear clawing at the window.
According to the Siberian Times, a commuter on a train near Tarbinskaya shot the footage last year. The film shows the burly creature lunging at the window several times, before a man can be heard saying "Mishka", the Russian term for "brown bear".
It is not known what incited the bear, though reports suggest some of the passengers may have been taunting the animal. Or he may have been running late for a breakfast meeting with his accountant.
