E4 Series Shinkansen
The E4 Series Shinkansen
were the second series of bi-level Shinkansen
high-speed trainsets to be built in Japan (the other being the E1 Series
). They are built for commuter service on the Tohoku Shinkansen and Joetsu Shinkansen lines; 25 units have been built beginning in 1997
. Two eight-car sets can be coupled together for extra capacity on busy routes.
