A train driver has been caught on camera playing Farmville whilst driving a train.

The driver was playing the game on his iPad while the train was visibly moving and travelling along the tracks. He was caught on camera by a passenger, who witnessed the event and decided to film it.

While texting and driving or the use of a mobile phone at all while driving a car is considered extremely dangerous, trains travel at speeds of over 100 km/hr and carry up to hundreds of passengers.

Carlo Segura Linares was able to film this train driver as he travels through Mexico City with the train's operator paying far more attention to his virtual farm than the train's controls.
