These trains are capable of speeds in excess of 300 mph.  Planning for their right of ways needs to allow for turning radius curvatures for high speed turning. This is another argument for making the Linear City path as straight as practical.


Because the linear induction motors that drive mag-lev trains use electricity, the train lines become prime locations for alternative energy systems.


Line of sight systems protect the trains, waveguide communications channels, and alternative energy systems that parallel each other along the train guideways.


Perhaps in the early phases of construction, the train network that forms the backbone of linear cities will contain a mix of trains from various kinds of light rail to mag-lev to various kinds of freight trains. Eventually, because of the quality and features possible with mag-levs, I hope they will dominate the passenger service. They may even become the train of choice for freight lines in the future.


When the trains move from point A to point B without stopping until reaching their destination, travel by train becomes efficient and effective.


Imagine a set of train tracks and guideways running parallel to each other. Each train exists on its own track. Each train only goes back and forth between two terminals (no reason for train collisions). The farther a train travels between its terminals, the faster it travels. The shortest distance trains are closest to the structures of the city. As you move away from the line of city you encounter a series of roughly parallel tracks. The farthest tracks from the city have the fastest tracks.


Exchangeways are intermodal terminals that facilitate connections between many kinds of transit options. There are various kinds of major and minor exchangeways in a linear city.


Major exchangeways would have hotels, convention centers, shopping and sports complexes in close proximity. All levels of trains have terminals in major exchangeways.


In the most densely populated segments of Linear City, the major exchangeways would have connections to gravity ramp transit systems in addition to the other, more common, transit machines. These ramps use free wheeling vehicles with no onboard engine. Raised by elevators, people get in soap box derby type vehicles and roll to destinations that may be a mile or two away. The return trip is usually accomplished the same way.


Minor exchangeways may be little more than whistle stops but could include arcades and passenger services depending on how many levels of track they serve. These would be the most common kind of exchangeways since most tracks have slower speed trains. The fastest trains do not stop at minor exchangeways.


The structural "rhythm" of the linear cities varies according to resources, climate, and geographical considerations. The train systems indicate this "rhythm" by the placement of major and minor exchangeways.


The beauty of this hierarchical train network is that it can be built as needed according to the population size and density along any given segment of a linear city. As the population increases, more levels of train get built because foresighted planners acquired the right of ways wide enough to allow growth and speed.


It should be possible to allow computer planned routing for passengers so they can select the train and transfer combination that best suites their needs. Because the combinations increase as travel distance increases, travel by train offers various kinds of freedom. *****


We may be seeing ever more need for disaster relief for large populations in the future.  Many people have been made suddenly homeless by natural disasters and human caused problems.  Tower Towns can be a way of helping people made homeless have a place to live.
