Context: The THSR 700T (台灣高鐵700T型電聯車) is the high-speed electric multiple unit trainset derived from the Japanese Shinkansen family for Taiwan High Speed Rail (THSR), Taiwan's high-speed rail line.  The THSR 700T is based primarily on the 700 Series Shinkansen, with the "T" referring to Taiwan.  The trains were manufactured in Japan by Kawasaki Heavy Industries, Nippon Sharyo, and Hitachi, Ltd., marking the first time Japanese Shinkansen trains have been exported overseas.  30 trains were delivered to THSR operator Taiwan High Speed Rail Corporation (THSRC), and are in regular service with a top speed of 300 km/h since the line's opening on January 5, 2007. The San'yō Shinkansen (山陽新幹線 , San'yō Shinkansen ) is a line of the Japanese Shinkansen high-speed rail network, connecting Shin-Osaka in Osaka with Hakata Station in Fukuoka, the two largest cities in western Japan.  Operated by the West Japan Railway Company (JR West), it is a westward continuation of the Tōkaidō Shinkansen and also serves other major cities in between on Honshu and Kyushu islands such as Kobe, Himeji, Okayama, Hiroshima, and Kitakyushu.  The Kyushu Shinkansen continues south of Hakata to Kagoshima.  The San'yō Shinkansen connects Hakata with Osaka in two-and-a-half hours, with trains operating at a maximum operating speed of 300 km/h , with the following exceptions: east-bound trains have a maximum speed between Himeji and Shin-Kobe of 275 km/h and west-bound trains have a maximum limit of 285 km/h from Shin-Ōsaka to Shin-Kobe and 275 km/h from Shin-Kobe to Nishi-Akashi.  Some "Nozomi" trains operate continuously on San'yō and Tōkaidō Shinkansen lines, connecting Tokyo and Hakata in five hours. The Shalun Line () is a branch line of the Taiwan Railway Administration (TRA) Western Line in Tainan City, Taiwan.  It was built to link the Western Line to the Taiwan High Speed Rail (THSR) Tainan Station, speeding up transit times between downtown Tainan and the THSR station, with services running from Nanke Station or Tainan Station to Shalun Station, next to the THSR station.  The line opened on January 2, 2011. Taiwan High Speed Rail (abbreviated THSR or HSR) is a high-speed rail line that runs approximately 349.5 km , along the west coast of Taiwan, from the national capital Taipei to the southern city of Kaohsiung.  With construction managed by a private company, Taiwan High Speed Rail Corporation (THSRC), which also operates the line, the total cost of the project was US$18 billion.  At the time it was built, this was one of the world's largest privately funded rail construction schemes.  The system is based primarily on Japan's Shinkansen technology. Hitachi, Ltd.

THSR Hsinchu Station () is an elevated station of Taiwan High Speed Rail located in Zhubei, Hsinchu County, Taiwan.  It opened for service in 2006.  The THSR Hsinchu Station was designed by Taiwanese architect Kris Yao. THSR Taichung Station () is an elevated station of the Taiwan High Speed Rail located in Wuri District, Taichung City, Taiwan.  Transfers can be made to Xinwuri Station on the TRA Western Line.  It was the only operational high speed rail station in Central Taiwan before any additional stations become operational on December 1, 2015, making this station the most isolated of all THSR stations.  The distance to the north to Hsinchu is 93 km, and south to Chiayi is 85 km. The 100 series (100系 , Hyaku-kei ) was a Japanese Shinkansen high-speed train type which operated between 1984 and 2012 on the Tokaido Shinkansen and Sanyo Shinkansen high-speed lines.  They were introduced after the 200 series trains, but their numbering is such because in the days of Japanese National Railways (JNR), Shinkansen types running east of Tokyo were given even numbers and those west of Tokyo odd numbers, hence they were given the next odd number in line after 0, 100.  The last remaining examples of the type were withdrawn from service following the last runs on 16 March 2012. Provincial Highway 31 () is a 17.876 km provincial highway in Taoyuan City, Taiwan.  An elevated section of the Taiwan High Speed Rail viaduct and under-tunnel acts as a median for most of the highway, except when the highway is near THSR Taoyuan Station and when the highway is near and on its southern terminus.  The highway serves the THSR Taoyuan Station. Xinzuoying Station (TRA, ) or Zuoying Station (THSR and KMRT), is a major railway station served by Taiwan Railway Administration, Taiwan High Speed Rail, and Kaohsiung Mass Rapid Transit located in Zuoying District, Kaohsiung, Taiwan.  Passengers can transfer between TRA Western Line, KMRT Red Line, and THSR at this station, and it is the only rail station in southern Taiwan where three rail systems converge.  The station handles over 64,000 passengers daily on conventional rail, metro, and high-speed rail.
