Railways were the first form of rapid land transportation and had an effective monopoly on long-distance passenger traffic until the development of the motor car and airliners in the early-mid 20th century. Speed had alwa… 詳細

Continuous welded rail is generally used to reduce track vibrations and misalignment. Almost all high-speed lines are electrically driven via overhead lines, have in-cab signalling, and use advanced switches using very low e… 詳細

All high-speed trains have been designed to carry passengers only. There are very few high-speed freight services in the world; they all use trains that were originally designed to carry passengers.
During the planni… 詳細

Key technologies used in high-speed train rolling stock include tilting trainsets, aerodynamic designs (to reduce drag, lift, and noise), air brakes, regenerative braking, engine technology and dynamic weight shifting. Notable … 詳細

While commercial high-speed trains have lower maximum speeds than jet aircraft, they offer shorter total trip times than air travel for short distances. They typically connect city centre rail stations to each other, while air tr… 詳細
