Let us begin with the jokey new term ‘ferrosexuals’, meaning people who experience wanton fetishistic desire for trains—also more romantically labelled ‘buffer kissers’. When I was a lass too young to have heard of the Mile-high Club, ferrosexuals were called ‘train-spotters’ and their ardour was seen as innocuous, if pitiably nerdy. Does the new term mean that machines for travel are now seen as sexy, because we live in increasingly sexualised societies? Or does it mean that an underlying sexual charge in people’s interest in trains is finally being made explicit and taken seriously? We do not know. And the reason we do not know is that scholarly work—particularly historicised work—has yet to be done on sexualities’ many interfaces with transport and mobility.
