Present Maglev systems cost 30 million dollars or more per mile. Described is an advanced third generation Maglev system with technology improvements that will result in a cost of 10 million dollars per mile. Plotkin, D.; Kim, S. Lever, J.H.
Maglev's unit capital costs surpass those of New HSR by lesser, but still significant, amounts, ranging from $11 to $19 million per mile in recent studies. Thus, the Maglev technologies of today are the most expensive form of HSGT in terms of up-front investment. times. Washington.
Compared to highspeed passenger rail, maglev passenger rail consumes roughly twice the power per passenger kilometer. For commercial freight I found an efficiency figure of 520 ton-miles per gallon (660 kg-km/MJ). Assuming 70kg for the average commuter passenger this gives us an efficiency of (116 kg-km/MJ) for maglev.
Hermann Kemper (* April 5, 1892 Nortrup, Germany, in the district of Osnabrueck, † July 13, 1977) was a German engineer and is considered by many the inventor of the basic maglev concept. In 1922, Hermann Kemper began his research about magnetic levitation.
SNCF, widely regarded as one of the best high-speed rail operators in the world, has had 4 profitable years and 5 loss-generating years since 2012. The Shanghai Metro Maglev has never been profitable. Clearly, there is an issue with passenger transport. No mode of transportation can consistently generate profits.
A series of German patents for magnetic levitation trains propelled by linear motors were awarded to Hermann Kemper between 1937 and 1941. An early maglev train was described in U.S. Patent 3,158,765, Magnetic system of transportation, by G. R. Polgreen on 25 August 1959.
Maglev trains are “driven” by the powered guideway. Any two trains traveling the same route cannot catch up and crash into one another because they're all being powered to move at the same speed. Similarly, traditional train derailments that occur because of cornering too quickly can't happen with Maglev.
Even if the power goes out, levitation forces keeps the train in the air while it is traveling at high speed. The vehicle comes safely to a stop rather than suddenly falling onto the track.
As it stands, commercial flights maintain a cruising speed ranging between 545 mph and 574 mph. Yet, once fully developed and optimized, the engineers behind this incredible feat believe the maglev could soar to speeds of up to 621 mph.
Cost concerns over innovative railThe primary challenge facing maglev trains has always been cost. While all large-scale transportation systems are expensive, maglev requires a dedicated infrastructure including substations and power supplies and cannot be integrated directly into an existing transportation system.
Maglev trains have some advantages over traditional trains. As the train does not touch the ground along the guide road, it does not have any moving parts, so there is no part to wear. For this reason, the maintenance cost is low. Since there is no contact with the guide track, there is no friction.
The design of the maglev cars and railway makes derailment highly unlikely, and maglev railcars can be built wider than conventional railcars, offering more options for using the interior space and making them more comfortable to ride in.
High-speed maglev (short for magnetic levitation) trains float on air because electrified metal coils in the guideway, or track, repel large magnets attached beneath the train. Since there's no friction, the train can go fast — more than 300 miles per hour!
