Transportation is the number one factor in the economic vitality of a culture. Our world culture has relied on the dominance of automobile/truck infrastructure, however that infrastructure is grinding to a halt and rather then fueling economic prosperity, it has become a burden to it. The necessity of finding a solution has been obvious for decades, however every solution that has been suggested thus far, has been either too expensive or inadequate to the task.
One of the biggest drawbacks to the road based transportation system is the lack of durability of the road surface and the need for constant maintenance. This means that money invested in infrastructure will need to be reinvested only a few years later. With the RailPlane system, the rails are made out of magnesium oxide cement rather than Portland cement. This material is far more durable than the more commonly used Portland cement and its long-term durability is demonstrated by the Great Wall of China, the Coliseum in Rome, as well as the Pantheon, all of which were constructed using magnesium oxide cement. This means that the rails can remain in service for many decades with only minimal maintenance requirements. Investments made now will have beneficial ramifications far into the future.
Many environmentally sensitive areas have poor roads and, for the people that live there, the cost of transportation per mile is higher on average than for those who live in areas where roads are more refined. The result is that a significant portion of the forest degradation is consequent upon the wealth that needs to be extracted to pay for an outdated means of transportation.
Many elevated rail systems are noisy. The noisiest installations utilize steel wheels on steel rails. RailPlane vehicles, on the other hand, would ride on urethane wheels over a smooth concrete surface, generating little noise in the process.
