【二階建てのE13系新幹線】E4系に続くオール二階建て新幹線は誕生するのか

The Multi-Amenity Express, commonly known as Max, was once a Shinkansen train featuring all double-decker carriages. Introduced by JR East, it was an all-double-decker Shinkansen targeting short- and medium-distance passengers. The E1 series debuted in 1994, followed by the E4 series in 1997, which incorporated a coupling and uncoupling device. Since then, Shinkansen trains have become faster, and unfortunately, the history of double-decker Shinkansen trains came to an end in 2021. Currently, there are no double-decker carriages on the Japanese Shinkansen, but there is a good possibility that double-decker Shinkansen trains will make a comeback in the future. This time, let's look back at the history of double-decker Shinkansen trains and consider together the possibility of their revival.
