The idea of getting the roller-coasters out of the amusement parks and into the city is old, but yet no one has managed to produce a valid and feasible solution for it.
The main problem until now was the safety issues rising when riding three-dimensional curvature paths. In roller coasters riders are restrained to their seats using safety measures which are clearly not suitable for urban transportation. Combining urban transportation and roller coasters technology into a single system creates the necessity of keeping the parallel movement of the train-car to the ground at all times. A steady parallel movement will allow a safe ride and the development of particularly efficient transportation systems.
