The Joyful Shinkansen made its debut between Ôsaka and Hakata in 2015, and marked two anniversaries: 40 years of the complete opening of the San'yô Shinkansen, and 20 years of the mecha anime Neon Genesis Evangelion. And it's safe to say the mash-up of a 500 Series rocketship and a giant robot was bound to work!
For two and a half years, this train ran one daily return on a Kodama service, until it became the Hello Kitty Shinkansen. When I visited Japan in 2016, I made a point to see it en-route to Hiroshima. Timetable-wise, Fukuyama was the right spot.
As a Kodama train, the 500 TYPE EVA wasn't the fastest, and would often wait for Hikari and Nozomi trains to pass before continuing. This was the case here, and here's an N700 overtaking.
Erm, that didn't look blisteringly fast, did it? Well, taking into account the size and distance it may not, but a very rough calculation (length of a 16-car N700 set: 400 m, in 6 seconds) yields a speed of 240 km/h. The speed limit on the San'yô high speed line is 300 km/h.
Back to the Evangelion train! As is the case in the Hello Kitty train, two cars received particular attention. Car 2 was a decorated seating car, and car 1, with windows covered, had a mock-up cockpit and simulator game!
With the overtake done, the 500 TYPE EVA set off. Riding it didn't fit into my schedule on that voyage, but it was great to see it. Best livery on a 500 in my opinion!
