This seems somehwat similar to the way that Intamin (a rollercoaster company) builds their wooden coasters. They machine all the sections of track in their factory, then send them to the construction site, just like with steel tracked coasters. Before, the way they did it was to just build the track using boards, which led to a rougher ride that made it harder to do some things like crazy banked turns and sharp drops. Wood. Good stuff.
