300 km

The 300 series (300系, San-byaku-kei) was a Japanese high-speed Shinkansen train type, with a top operational speed of 270 km/h (170 mph), which operated on the Tokaido and Sanyo Shinkansen lines in Japan between 1992 and 2012. When first introduced, they were used on the fastest Nozomi services, being capable of 270 km/h (170 mph). As more were delivered (66 trains by 1998) they replaced earlier units on Hikari service and allowed the thus displaced 100 series units to finally in turn displace 0 series units on almost all services.
With the introduction of newer 700 series and N700 series equipment, the 300 series sets were gradually demoted to slower Hikari and Kodama services, and were completely withdrawn from Tokaido and Sanyo Shinkansen services by the start of the revised timetable on 17 March 2012.
