Train Details
This train provides service along the Koumi Line, which has many attractions, such as the panoramic views of Mount Yatsugatake and other mountainous terrain, bountiful harvests from the long days and extreme temperature differences, and excellent nighttime star-gazing.

Origin of the name
The Koumi Line, which connects Kobuchizawa Station in Yamanashi Prefecture to Komoro Station in Nagano Prefecture, also known as the Yatsugatake Kogen Line, runs at the highest elevation of any Japan Railways line. This train was named HIGH RAIL 1375 in order to highlight the high elevation of the Koumi Line, which has the highest section of “RAIL” of any JR Line at 1,375 meters above sea level, between Nobeyama and Kiyosato stations. The name was chosen in the hope that visitors will enjoy how starry the sky is when seen from the high elevation of the Koumi Line.
Design
Exterior
