The Maglev Water Train is a new option for transporting water at low cost for hundreds of miles. Not only is the Water Train much cheaper than pipelines, it is able to traverse terrains that have rapid changes in elevation, without having to incorporate pumping or turbine stations to adjust pipeline water pressure due to variations in elevation. The high speed maglev vehicles automatically compensate for upgrades by slowing down slightly as kinetic energy is transformed to gravitational potential energy. On downgrades, the gravitational energy automatically returns to kinetic energy as the vehicle increases speed.

The maglev Water Train can deliver 2 billions gallons of water per day - enough to supply 100 million people with 20 gallons daily - over a distance of 500 miles. The total cost of delivery, including the amortization of the vehicles and the guideway, plus vehicle operating and maintenance cost, is approximately 1 dollar per 1000 gallons. This is comparable to the present cost from municipal water supplies. If there is a net downslope of the maglev delivery route, water would be collected at higher elevations and transported to lower lying areas. An average downslope of 1 meter per kilometer of travel supplies sufficient gravitational energy to overcome all air and magnetic drag forces on the vehicle, reducing the total delivery cost to only 57 cents per 1000 gallons. Such a down grade is very gentle, and generally found in most large river basins.

The Water Train, besides supplying water to large, highly populated regions, could also serve to transport passengers and freight.
