Lots of train incidents (and car crashes, for that matter) occur because the driver has dozed off. And lots of them are male. Potentially more, at a guess, as "dozing off" when over-tired is actually a more male trait biologically speaking, to conserve energy for physical activity (hunting, fighting) whereas females tend to be able to stay awake more easily when tired, probably linked to being biologically geared towards caring for infants. Think of the stereotypical "man dozing off infront of the telly".

So yeah... Men are theoretically more prone to falling asleep at the wheel than women. Though I don't have any actual crash statistics to back that up.

My dad is constantly preaching the "never drive tired!" Message, as he fell asleep at the wheel on the way home from a nightshift many years ago. He ended up with a bashed up car being dragged out of a field by a farmers tractor... he wasn't hurt, but it could obviously have been much, much worse. Especially if he had strayed onto the wrong side of the road and hit another car.
