means The Japanese high-speed rail network (and its trains), famous for connecting major cities at speeds over 300 km/h with legendary punctuality.

from From Japanese shinkansen (新幹線), literally 'new trunk line' — shin (new) + kan (main/trunk) + sen (line). The name is almost defiantly plain: it describes rail infrastructure, not speed or glamour. The first line, the Tōkaidō Shinkansen, opened in 1964 between Tokyo and Osaka, timed to debut alongside the Tokyo Olympics, and became the world's first dedicated high-speed rail system. The nickname 'bullet train' came later, from English-language press struck by the train's sleek, bullet-shaped nose — the Japanese name never mentions speed at all.
