train surfing 

An extreme sport popular in Soweto, South Africa.

It includes things like hanging onto a moving train and sliding your feet on the platform, standing on the roof and dodging powerlines, jumping on and off repeatedly, jumping from a bridge onto a moving train and jumping between carriages. The more dangerous the stunt, the better.

It is illegal, and fatalities are common

Sipho and Themba went train surfing from Dobsonville to Orlando.

trainsurfing 

The act of riding a train in any method except inside the train cars. In other words, it's the equivalent of Ghost riding a train.

Usually the act is performed by hanging onto the back, sides, or top of the train while the train is in motion.

The most common target are passenger trains (due to their ease of getting on and off the train at stations) primarily as an extreme sport.

There are some awesome videos on Youtube of trainsurfing.

trainsurfing 

The act of riding the exterior of a railway carriage. The only upside of this activity is the high likelihood of the surfer being squished, thus removing himself from the genepool.

"Another kid died trainsurfing."
"It's just natural selection in action."
