Maglev Buses were buses without a wheel and wheels and axles. Instead, they hovered on magnetic fields.

(Note: The background section of this page uses most of the same words as Terra Futura's page on fuel cell buses to save time.)


Early buses were drawn by horses. These horsebuses became commonplace in 1820s. They were first used in Berlin and then spread to other parts of the world. Then, in 1830, Walter Hancock invented the steam bus. They were in England until harsh legislation nearly drove steam buses to extinction. This legislation was later repealed in 1896. Steam buses came back into services. Meanwhile, in 1882, the electric trolleybus was invented. These trolleybuses used overhead wires just like electric trains. Then, in 1895, the first internal combustion engine bus was invented. Early buses used gasoline, but, in 1920, the first diesel buses came into existence.

Diesel buses started to be used in the 1920s because they had 50% efficiency. Diesel buses went on to become the most common buses on Earth. There were two problems to contend with. First, diesel fuel had a high sulfur content which would be eliminated. Second, diesel engines released particulate matter in the form of smoke. This was solved by a diesel particulate filter. By the end of the 20th century, there was an even bigger problem. That was global warming caused by greenhouse gas emissions. Diesel fuel would be replaced with bio-diesel fuel.

Bio-diesel buses had an advantage over conventional diesel buses because of the fuel. Bio-diesel did not need to be refined at all. After being created from plant crops, the fuel was already good to go as diesel. Therefore, bio-diesel buses quickly got onto the market. They were more environmentally friendly than conventional diesel buses and, thus were commonly used. But they were not the only replacement for conventional buses. Natural gas buses were more common.

Natural gas released less emissions into the atmosphere than petroleum. Thus, it was a cleaner fuel. One of the first transit authorities to natural gases buses was the Dallas Area Rapid Transit (DART) in Dallas, TX and its suburbs. This part of a move to reduce carbon emissions in the Metroplex. The replacements began in 2013. Soon, they were commonplace. However, as hydrocarbons ran out, buses needed a new source of power. As a result, many buses became hybrids.

In the early 21st century, hybrid electric buses started coming onto the market. As battery weight decreased significantly, hybrid buses became cheaper. They were now more widespread than ever. Equipped with regenerative braking and a start-stop system, emissions were reduced, and power was not lost when the brakes came on. Hybrid buses were a success. Soon, plug-in hybrid buses would come onto the market.

In 2013, the first plug-in hybrid bus was prototyped by Navistar for schools. This bus had an electric range of 40 miles. Beyond that, a bio-diesel engine provided extra distance. This was funded by the United States Department of Energy. Other companies used natural gas for the internal combustion engine of their plug-in hybrid buses. By the 2020s, plug-in hybrid buses were commonplace. This was one step in the transition to electric buses.

The electric buses of the 21st century were very similar to the electric trolleybuses of the 1890s with one exception. They were autonomous. Some were powered by lithium-ion batteries. Some by zinc-air batteries. Some were solar-powered. Others were powered by ultracapacitors. The lithium-ion variant was the most common because it was the longest lasting, it was rechargeable, and the power was available 24/7. By the 2030s, all buses were electric. Some electric buses were fuel cell buses, too.

As advances in hydrogen fuel cells came into existence, they could be used in buses. Many different car companies had been working on fuel cell cars. Fuel cells were being deployed on buses by the 2020s. By the mid-21st century, they were commonplace. The fuel cells were often accompanied by an ultracapacitor and sometimes a battery for extra power. A dream of the future became the reality of the present for buses and cars. However, as room-temperature superconductors were discovered, these gave way to maglev buses.


Tech Level: 11-12

As maglev technology improved, vehicles got larger. By the end of the 2080s, maglev vehicles were now large enough to fit more than one family. Maglev buses were now in service. They could transport from a vactrain terminal to a bus stop in no time. This revolutionized public transportation. They could also go anywhere that was previously inaccessible. Eventually, however, maglev buses would give way to buses that used gravitic technology.
