What propels Japanese bullet train?

Instead, it actually uses magnetic forces to both elevate the train and propel it forward. The magnetic force is created by the interaction between metal coils in the rails or guideways and the superconducting electromagnets on the train itself.



The Japanese bullet train, or Shinkansen, is propelled by a sophisticated electric motor system that draws power from overhead catenary lines. Unlike traditional trains where a single locomotive pulls the cars, the Shinkansen uses an "Electric Multiple Unit" (EMU) system. This means that powerful electric motors are distributed under several cars throughout the entire length of the train. This distribution of power allows for rapid acceleration, smoother braking, and the ability to climb steep grades more efficiently. The electricity—usually 25,000 volts AC—is picked up by a "pantograph" on the roof of the train. In the newest models, like the N700S, the propulsion system utilizes Silicon Carbide (SiC) power devices, which make the train lighter and more energy-efficient. Furthermore, for the future "L0 Series" Maglev Shinkansen currently in testing, propulsion is achieved through magnetic levitation and linear motors, where powerful magnets on the train interact with coils in the guideway to "pull" the train forward at speeds exceeding 600 km/h without any physical contact between the wheels and the track.

Electrical systems Shinkansen uses a 25 kV AC overhead power supply (20 kV AC on Mini-shinkansen lines), to overcome the limitations of the 1,500 V direct current used on the existing electrified narrow-gauge system. Power is distributed along the train's axles to reduce the heavy axle loads under single power cars.

High speed trains run on electricity instead of diesel fuel. Because much of the world's electricity is still generated at fossil fuel burning power plants, high speed trains do contribute to carbon emissions, however the climate impact of one train is significantly less than that of many personal vehicles.

The magnets employed are superconducting, which means that when they are cooled to less than 450 degrees Fahrenheit below zero, they can generate magnetic fields up to 10 times stronger than ordinary electromagnets, enough to suspend and propel a train.

MORE DETAILS

The shinkansen train uses superconducting maglev (short for magnetic levitation) to achieve these incredible speeds. As the train leaves the station, it's rolling on wheels. But as it speeds up, the wheels retract, and the power of magnets allows the vehicle to hover four inches above the ground.

MORE DETAILS

There's no rail friction to speak of, meaning these trains can hit speeds of hundreds of miles per hour. Yet high speed is just one major benefit of maglev trains. Because the trains rarely (if ever) touch the track, there's far less noise and vibration than typical, earth-shaking trains.

MORE DETAILS

Maglev, which is derived from the term 'magnetic levitation', is a transport method that employs magnetic levitation to move the vehicle without touching the ground. With maglev technology, a vehicle travels along a 'guideway' using magnets to create both lift and propulsion.

Bullet Train Speeds and Safety Despite these insane speeds, bullet trains are remarkably safe. In fact, the Shinkansen has had no accidents since its creation in 1964. That's over 50 years accident-free. Punctuality and safety are only two of the train's most advantageous features.

There is a custom in Japan where most people do not eat food outside other than when in restaurants. However, when using the bullet train or the green car, you are permitted to eat food. Normal trains and people commuting using said trains do not permit the consumption of food whilst riding the train.

The train's tilting mechanism to lean into curves at high speed and the high-quality airtight body minimize vibration and provide a smooth, quiet ride.

In addition, the tracks, signals, rail cars and software made in the U.S. are costlier than imports, largely because the government has not funded rail the way European and Asian countries have, experts say.

The train used for the movie, the “Nippon Speed line” is fictional, although it bears some similarities to the real Shinkansen on the line between Tokyo and Kyoto.

MORE DETAILS

All shinkansen are equipped with multiple toilets, which are sometimes separated by gender. The toilets are Western-style except on some older train sets.

The ATC system prevents high-speed passenger train-on-train collisions and excessive speeds. The advanced ATC system exercises complete control over the entire dedicated track and every operating train, preventing train-on-train collisions and excessive speed.

The Shinkansen operates 365 days a year, and 800 kg to 1 ton of garbage are collected every day. At the end of a day, staff will spray 30 fold diluted Activated EM-1 on the floor, belt conveyer and compressed pet bottles and cans. “We have been using EM for many year so we got used to it not being smelly here.

The Superconducting Maglev is equipped with a braking system capable of safely stopping a train traveling at 311mph. Regenerative braking is normally used for deceleration, but if it becomes unavailable, the Superconducting maglev also has wheel disc brakes and aerodynamic brakes.

MORE DETAILS

Types of bullet trains On each of the Shinkansen lines there are fast trains, semi-fast trains, and local trains: The fast trains only stop at the main stations. Semi-fast trains make a few more stops. Local trains stop at every station.

The track level is about 100 m (330 ft) below the seabed and 240 m (790 ft) below sea level. The tunnel is part of the standard-gauge Hokkaido Shinkansen and the narrow-gauge Kaikyo Line of the Hokkaido Railway Company (JR Hokkaido)'s Tsugaru-Kaikyo Line.

Japanese train stations are non-smoking areas, except for specific closed spaces called Kitsuenjo ??? smoking area. Smoking is not allowed on trains. There are some rare exceptions on the fastest trains (like the Shinkansen), that are sometimes equipped with smoking cars.
