Intercontinental Train System - My biggest infrastructure vision is for an Intercontinental Train System. This train will cross the baring strait, and be able to travel from South Africa to South America in 4 days or less. The train will be 100 ft wide and designed in the maglev model, which maximizes speed and safety. All trips will be direct non-stop. In order to do this each car will have an engine of its own, and cars will be able to detach and reattach while moving. This way passengers can get on one car, and that car will then connect to a main track where it will attach to the front or back of a group of cars. Once attached, passengers can move to a car that is going to their final destination. Passengers may have to move multiple times if they are going long distance. Some cars will be dedicated to sleeping and entertainment and will essentially be permanently attached to the group of cars in the middle of the train. Entertainment sections may have swimming pools and movie theatres. People traveling long distance can move to sleeper cars before eventually switching to a normal passenger car once they're near their final destination. A computer system can notify people via text when they need to move from one car to another in order to keep everything organized and maximize capacity.
The train will also be designed for transporting goods. The plan is to have the bottom of the train have detachable semi-truck trailers. Essentially once a train car stops at its destination a semi truck can pull up underneath the train and trailers will detach from the train and attach to the back of a semi. Other semis can then pull up and attach their trailers onto the train. Once a car is attached to the main track and a group of cars, there would have to be some method for the trailers on the bottom to move to another car that is going it's final destination, other wise separate cars would have to be used to transport products. The train will be built on the outskirts of current cities in the interior of the country. Industrial areas and factories can be built around the train stops in order to maximize the efficiency of loading.
