E5 Series Shinkansen
The Shinkansen E5 series (Japanese新 干线E5系 电车, Shinkansen E5 -kei densha ) is a Japanese high speed train operator JR East. The E5 series is based on the test train FASTECH 360 and is used for the Tohoku Shinkansen line. The design of the head - end cars in the series and E5 are particularly streamlined designed, in particular to counteract the tunnel bang.
History
The E5 series was developed directly from the experimental high speed train FASTECH 360. The aim of the project was to replace the trains of the series 200 and series E1. After the successful end of the project FASTECH 360 10 preseries trains E5 series were produced. The first pre-series with the designation S11 was delivered in May 2009. Compared to the 360 FASTECH the car's nose was shortened from 16 to 15 meters. The tests were mainly between Sendai and Kitakami. As part of these tests reached S11 a top speed of 320 km / h in continuous operation. Thus, the pre-production vehicles were able to meet the requirements of mass production, so that 49 production models were commissioned. The pre-production vehicles were converted to standard series and are in commercial use.
The first three series trains were first used as Hayabusa connection 5 March 2011 between Tokyo and Shin- Aomori or Sendai. The trains travel at a maximum speed of 275 km / h between Utsunomiya and Ōmiya and of 300 km / h between Utsunomiya and Morioka. On November 19, 2011, three more series trains were taken to the Hayate and Yamabiko connections operation, while the maximum speed of trains to 275 km / h ( between Omiya and Utsunomiya to 240 km / h) is limited. Thus, some trains can be coupled to the E3 series between Tokyo and Morioka. As of early 2013, the maximum speed of the Hayabusa connection between Utsunomiya and Morioka to 320 km / h should be increased.
Once the E6 series is supplied as a replacement of the E3 series, the trains of the series will be operated E5 on the Yamagata and Akita Shinkansen the Series E6 in traction at a top speed of 320 km / hr.
Facility
Unlike most other Shinkansen trains, the E5 three classes: the normal class ( 2nd class), the green class ( 1st class) and the gran class.
The second class, normal class
The second class is the easiest to set up and thus also the cheapest class of Shinkansen E5. The chairs have a distance of 1,040 millimeters.
The first class, green class
The first class is more luxurious than the second class. The 48 seats per car at a distance of 1,160 millimeters. The seats are 475 mm wide.
The gran class
The gran class is the most luxurious and therefore also the most expensive class in the train. The seats have a distance of 1.300 mm and a width of 520 millimeters.
Technology & Appearance
The current collector of the E5 series is a special feature: To reduce noise emissions, was a requirement for the development of the series E5, that the pantograph must always be aligned in arrow form in direction of travel. In order for a change of direction, this is still the case, a second, mirrored mounted pantograph could be used. However, should a defect in a current collector, wherein the current collector can not be retracted, had the consequence that either with two pantographs or a misaligned pantograph would have to be driven. This would have led to problems with the noise requirements, and in the worst case, the vehicle should have been taken to repair the service. It was therefore decided to develop a new pantograph type that can always be oriented in the direction of travel ( see photo).
The Shinkansen E5 series sees the FASTECH 360 outwardly very similar. The car's nose has been shortened by one meter to 15 meters. The upper half of the trains is turquoise / green, the lower white, in the middle runs a pink stripe.
Fleet
As of August 2013 28 trains have been delivered, including pre-production.
