Russian strong-woman Oksana Kosheleva dragged two 18-ton tram cars full of passengers along a short track in sub-zero Siberia in her latest public power stunt.

The 33-year-old¡¯s show of strength, which required six months of training, took place on Monday in her home town of Irkutsk, where temperatures dropped to minus 20 degrees Celsius.

¡°I had some (doubts) because of the cold. We were promised minus 11,¡± she told reporters after pulling the cars approximately 5 meters.

Kosheleva had dragged a one-car tram and a helicopter in previous power performances, but this was her first winter pulling attempt.

Wrapped up in warm clothing and wearing a harness, Kosheleva crawled along a ladder placed along the tram tracks. She was roared on by spectators while her coached slapped her back in encouragement.

A former contestant in the Russia¡¯s strongest woman event, Kosheleva said that she has now set her sights on pulling a passenger airliner.
