The Shinkansen series E7 ( Japanese 新 幹線 E7 系 電車 , Shinkansen E7-kei densha ) and the Shinkansen series W7 ( Japanese 新 幹線 W7 系 電車 , Shinkansen W7-kei densha ) are two identical Japanese high-speed trains that are designed for use on the Hokuriku Shinkansen can be procured from JR East and JR West .
history
New vehicles had to be procured for the second construction phase of the Hokuriku Shinkansen between Nagano and Kanazawa. On the first construction phase, which has been in operation as the Nagano Shinkansen since 1998 , trains from the N series of the E2 series were used, the oldest trains of which date from the mid-1990s and have been undergoing a general overhaul since the end of 2013. In December 2011, JR East therefore announced that new E7 series vehicles would be procured for the new route. In January 2012, the Kanazawa director of JR West announced that the new vehicles would be jointly developed with JR East. The aim is to receive the trains from the manufacturer a year before the line goes into operation so that the trains can be extensively tested in snow during the winter season.
The first E7 series pre-series train was officially delivered on November 29, 2013 . Before the trains are used on the Hokuriku Shinkansen, they were also tested on the Tōhoku Shinkansen .
The trains of the E7 series have been in service on the Asama connections of the Nagano Shinkansen since March 15, 2014 .
In April 2014, the W1 series W7 pre-series train was delivered to JR West. The delivery was made by Kobe by sea, so that the vehicle had to be reloaded from the ship to low-loaders at the port of Kanazawa in order to be brought to the Hasukan Shinkansen depot. The vehicles were presented to the public for the first time in June 2014.
In April 2015, JR East and JR West announced that they had each ordered an additional set of the E7 and W7 series in order to be able to replace the last E2 series trains on the Asama connection.
technology
Since the E7 / W7 series is to become the immediate successor to the E2 series , their requirement profiles are very similar. Compared to the E2 series, the E7 / W7 series vehicles are said to be more environmentally friendly with higher performance and offer better passenger comfort. As a performance requirement, JR East demanded from the manufacturers that the trains could be operated continuously at 210 km / h even on steep inclines in the mountains. On the new section, the trains are to be operated at a maximum speed of 260 km / h, the technical maximum speed of the trains is 275 km / h.
To minimize noise pollution, the side of the vehicle has been clad with special noise absorbers and a new type of pantograph is used.
Car 12 is equipped with full active suspension so that passengers in the Gran Class can travel particularly comfortably. All other cars are equipped with semi-active suspension.
As with the E5 and E6 series, the E7 / W7 series brake system is supplied by the German manufacturer Knorr-Bremse . In order to meet the requirements of the mountainous route of the Hokuriku Shinkansen, the brakes have to generate up to 600 kW and withstand temperatures of up to 700 ° C.
The E7 / W7 series will be procured as a 12-car formation, making it four cars longer than the E2 series N-series that it will replace. This increases the number of seats from 630 in the E2 series to 934 in the new vehicles.
Train composition
The E7 / W7 series consists of a total of twelve cars, including two non-powered end cars and ten powered intermediate cars. Car 11 is the Green Class (1st class), Car 12 is the Gran Class , which was first introduced in the E5 series.
