Emile Bachelet

Emile Bachelet was born in France in 1863. His invention is one of the premier and fundamental predecessors of the technologies surrounding modern electromagnetically levitated trains. In 1914, the French-born American inventor Emile Bachelet presented his idea of a maglev vehicle and even displayed a first model. A report in the Swiss journal "Schwizer Familie" in the year 1914 shows a photograph of this event and provides some information about his project vision, as well as the model. Photographer unknown.

A first magnetic field is designed to levitate the carrier, which is made of a non-magnetic metal but which hold its own set of magnets that react with the magnetic field of the pathway. It then “floats” in the air and can be propelled like a plane without mechanical friction. Another magnetic field is used to make the carrier move along with another series of magnets that are activated to attract other magnets on board the carrier (the repulsion/attraction pushing the carrier forward) while it is levitated (although this propulsion could also be obtained by classical means). Finally, the guidance of the carrier along the pathway can also be controlled using a third magnetic field. Emlie Bachelet (center with his arms elongated), demonstrates and explains to visitors how his magnetically levitated railway works. This takes place at his laboratory in Great Saffron Hall, Hobborn Circus, London, Circa 1914.

Although the patent described details such as how to savae electricity by activating the magnets just before the passage of the train and cut the current after it has passed, it should be recalled that, at that time, the development of electric locomotives functioning on a reliable and powerful source of electricity to propel real commercial freight or passenger trains that would later overcome steam locomotivs had not even begun. In addition, the system required, and still requires nowadays, the construction of a specific network. Nevertheless, Bachelet’s invention undoubtedly paved the way for modern maglev trains, like the Chinese Transrapid of Shanghai or the Japanese Linimo of Aichi.
