Is operating a train something that needs the driver's constant attention? I don't know, I'm not a train driver, but I'm pretty sure if I saw my driver playing a video game while he was in charge of the metal boxes I was hurtling around in, I'd be at least a little worried.

Carlo Segura Linares shot this video of a Mexico City train driver passing the time playing Farmville on his iPad Mini.

So we have people spending their spare time driving trains for fun, while people who drive trains for a living are spending their working time playing games. OK.
