What does the term 'Bullet Train' refer to?

The term 'Bullet Train' specifically refers to Japan's high-speed train system, known for its exceptional speed, safety, and efficiency. These trains, called Shinkansen in Japanese, serve various routes across the country and are renowned for traveling at speeds of up to 320 km/h (approximately 200 mph). They revolutionized train travel and are characterized by their streamlined design, punctual schedules, and smooth ride.

The other options do not accurately represent the Bullet Train’s definition. While a type of cargo train could involve trains that transport goods, it does not relate to the speed or passenger service of the Bullet Train. Scenic route services focus on travel experiences that highlight beautiful landscapes, which is not the primary purpose of the Bullet Train. Lastly, a luxury train experience may provide plush amenities and various onboard services but does not specifically denote the high-speed capabilities associated with Bullet Trains.
