Cambodia is littered with old bits of infrastructure from the French occupation and colonization, including a whole bunch of train tracks. Many of the trains are long gone, but that doesn't mean the tracks are out of use.

According to the description on this video, the trains are held together by nothing more than the weight of the components and sheer momentum. I'm going to go ahead and say that maybe the prayers of the occupants on this "train" might as well be helping as well.

You know, except for the entire lack of any safety precautions that would perhaps stop your head from popping right off your shoulders in the inevitable massive accident, that looks like a lot of fun.
