context_page_description: The 0 series trains were the first generation Shinkansen trainsets built to run on Japan's new Tōkaidō Shinkansen high-speed line which opened in Japan in 1964. The last remaining trainsets were withdrawn in 2008.
context_section_description: These 12-car SK sets based at Hakata Depot were operated by JR-West on Sanyo Shinkansen West Hikari services between Shin-Osaka and Hakata. Sets were formed of upgraded 5000 and 7000 subseries vehicles with improved seating, and buffet cars were refurbished with a special seating area. All standard class cars had upgraded 2+2 seating. The sets were recognizable externally by the addition of an extra thin blue line below the windows (similar to 100 series) and by the large "West" decals near the doors. Some sets originally included specially converted cinema cars, but these were withdrawn in 1996. Following the end of the West Hikari services on 21 April 2000, the remaining SK units were reformed into new 6-car R60 sets to replace unrefurbished sets on Sanyo Shinkansen Kodama services.
