A typical high-speed bullet train set, such as the Japanese N700 Series Shinkansen, has a formidable total power output of approximately 22,905 horsepower (17.08 megawatts). This power is not generated by a single "engine" but rather by numerous distributed traction motors across multiple cars.
Bullet trains utilize a distributed power system, meaning that many or all of the train cars are equipped with electric motors that provide propulsion. This differs from traditional locomotive-hauled trains, where one or more dedicated engines pull the rest of the unpowered carriages. This distributed power design allows for excellent acceleration, deceleration, and high-speed stability.
N700 Series Shinkansen Power Specifications
The N700 Series Shinkansen, a prime example of modern high-speed rail technology, demonstrates the significant power required to propel trains at speeds exceeding 250 km/h (155 mph). A standard 16-car N700 Series train set is equipped with an impressive array of traction motors to achieve its high performance.
| Feature | Specification (N700 Series - 16-car set) |
|---|---|
| Total Power Output | 22,905 hp (17.08 MW) |
| Traction Motors | 56 individual motors |
| Power per Motor | 409 hp (305 kW) |
| Maximum Speed | 285 km/h (177 mph) (Tokaido Line) |
| 300 km/h (186 mph) (Sanyo Line) | |
| 260 km/h (162 mph) (Kyushu Line) | |
| Weight | 715 tons (715 t) |
Each of the 56 traction motors contributes 409 horsepower (305 kilowatts) individually. When combined, these motors provide the immense collective power output of over 22,900 horsepower, enabling the train to reach its high operational speeds across various lines. This distributed power system is crucial for the efficient and rapid acceleration and braking capabilities that define bullet trains.
