It was brought to my attention by a reader (thanks J.G!), that JR East will introduce the E7 Series Shinkansen on the Hokuriku Shinkansen Line (currently named the Nagano Shinkansen Line) starting from 2015.
This follows the E5 Series, currently running along the Tohoku Shinkansen Line, and the E6 Series, which will run on the Akita Shinkansen Line from next year.
From a Mainichi Newspaper article:
According to JR East, the company is already working on a blueprint for the new model and will launch a prototype train by summer 2012.
…which means we’re just a few months away from seeing what kind of design it will have. Will it inherit anything from the E5 or E6? Or will it have a complete resdesign altogether? We’ll see.
With the formal announcement of the E7, I’m hoping that they’ll finally announce something for the Joetsu Shinkansen Line since they’re planning to retire the trains throughout the next few years.
