Beginning in 1983, surface rail lines in the city were moved underground as part of the Taipei Railway Underground Project. The Taiwan High Speed Rail system opened in 2007. The bullet trains connect Taipei with the west coast cities of New Taipei, Taoyuan, Hsinchu, Taichung, Chiayi, and Tainan before terminating at Zuoying (Kaohsiung) at speeds that cut travel times by 60% or more from what they normally are on a bus or conventional train. The Taiwan Railways Administration also runs passenger and freight services throughout the entire island.
