At peak times, such as during the holiday seasons, shinkansen can become extraordinarily crowded, with usage rates of 200% (meaning that up to 100 people can be standing, in addition to seated passengers, in each carriage). Trains travel at speeds of up to 300 km/h (approx 187 mph) and the network has never suffered a serious accident.
Shinkansen punctuality is legendary: the average lateness per train on the Tokaido Shinkansen in 1999 was just 24 seconds! Another curiosity: all seats in the carriages can easily be rotated by passengers to either face the direction of travel or to form bays of four or six seats.
Safety in a World of 300-km/h shinkansen
Although each Shinkansen is equipped with world-class, advanced operational systems and is kept in working order with sophisticated maintenance and repair technology, this does not mean that safety measures are infallible. When they first started operating, the maximum passenger-carrying speed allowed for these trains was 210 kph (130 mph). Strong competition with airlines, however, has led the JR companies to develop new Shinkansen models, each designed for faster speeds. Trains running at 300 kph (185 mph) were put into service in March 1997, and research has begun on magnetically levitated trains that will eventually go 500 kph (310 mph).
The faster trains travel, the more they shake and vibrate, imposing a greater load on the wheels and axles. Experts point out that at very high speeds, even a tiny flaw may result in a catastrophic breakdown.
Preparing for earthquakes, too, gives railway authorities cause for concern. Shinkansen railways employ an emergency braking system that is triggered when an earthquake occurs. The faster the train is moving, however, the longer the braking distance--and a longer braking distance means more time during which a moving train can actually be shaken by an earthquake.
Over the past 45 years, the average delay is less than one minute - and that includes stoppages because of floods, earthquakes, accidents and natural disasters. Rail officials also note their safety record: There's never been a passenger fatality on the Shinkansen.
this one data till year 2010.. earthquake also did not accident, how japanese did that ??
chinese punya train tak earthquake pun banyak mampus
