As FASTECH 360 two be prototypes of the newest generation of Japanese Shinkansen - high-speed trains called. They are designed for a technically permissible maximum speed of 405 km / h and a planned maximum speed in regular operation of 360 km / h. The term "FASTECH 360" is a new word created from Fast , Technology and 360 (km / h).
technology
Some new techniques were tested with the FASTECH 360.
- The trains are equipped with an emergency air brake that increases air resistance , as is common in the aviation sector. Its shape is reminiscent of cat ears. This enables FASTECH 360 trains to stop traveling at 360 km / h with an emergency braking within 4000 m. The air brakes are installed on seven vehicle parts from the E954 series and on five vehicle parts from the E955 series.
- Each pantograph has a newly developed twelve-part contact strip . The aim is to improve the transmission of electricity between the overhead contact line and the train so that the trains can run with just one pantograph. This measure also reduced the noise generated by the pantographs.
- By regulating the air pressure in the secondary springs of the bogies , the car bodies of the FASTECH 360 can be inclined by 2 degrees in order to drive through curves with radii of 4,000 meters on the Tohoku Shinkansen at 330 km / h and 6,000 meters at 360 km / h .
- End cars with different bow shapes were built to compare which shape is more suitable for reducing the tunnel bang . The E954 series had a bow length of approx. 16 m in streamlined design like the 500 series in the first car (E954-1) and an arrow design like the Shinkansen E4 series in the eighth car (E954-8). The E955 series has an end car with an arrow design and a 13 m front length (E955-1) and one with a 16 m front length (E955-6).
During the test drive of a coupled train with the E954 and E955 series, it could only comply with the statutory upper noise level limits up to 330 km / h. Because of the high costs of noise protection measures on trains and routes, the planned maximum speed of the new E5 and E6 series vehicles was limited to 320 km / h. Without the aerodynamically acting air brakes, the train was able to maintain a braking distance of 4000 m with the disc brakes and rapid braking. Therefore, the air brake was not used on the series trains.
Train types
After the test drives between March and June 2003 with the E2 series (with a speed of up to 362 km / h) and E4 series (with a speed of up to 340 km / h), two prototype trains were developed.
FASTECH 360 S (Series E954)

The code letter S is the first letter of Shinkansen. The train was produced as a new Shinkansen train especially for Tōhoku Shinkansen and named as S9 set. It had eight cars: a buffet car (E954-4), a 1st class car (E954-5) and six 2nd class cars. The train ran test runs on the Tōhoku Shinkansen from June 2005, and later also on the Jōetsu and Hokuriku Shinkansen (only between the Takasaki and Karuizawa stations). During a test drive on the Tōhoku Shinkansen on March 1, 2006 between the cities of Sendai and Kitakami, a top speed of 368 km / h was reached. The invited press representatives described the vibrations and driving noises at 360 km / h as comparable to the E2 series at a top speed of 275 km / h. During test drives in August 2005, speeds of up to 398 km / h were achieved. At a speed of up to 340 km / h, the train was able to comply with the statutory noise protection limits. The vehicle was scrapped after the end of the test program in September 2009.
FASTECH 360 Z (Series E955)
The second test train with the designation S10 was made for the mini Shinkansen . In FASTECH 360 Z, the "Z" stands for Zairai-Sen ( 在 来 線 , German for "conventional route"). The test train S10 consisted of six cars: a buffet car (E955-5), a 1st class car (E955-2) and four 2nd class cars. The third car (E955-3) did not have an air brake. The test drives began in 2006 on the Tōhoku Shinkansen. The train was later tested on the Akita Shinkansen . The train was retired in December 2008.
On the basis of the FASTECH 360 Z, the Shinkansen series E6 was developed, which has replaced the vehicles of the E3 series on the Akita Shinkansen since 2013 .
