train surfing(redirected from Trainrider)
train surfingRiding on a train outside of the carriage, which is done in two different contexts:
(1) People who cannot afford the usual train fare in places such as India, Indonesia and South Africa, and are thus relegated to sitting or standing on the outside of moving trains for free; here, danger is an undesirable factor.
(2) Young (often male) adrenaline junkies who ride the outside of trains for the thrill of danger, or to film their exploits.
