Q:Information: - Busan;, officially Busan Metropolitan City(), romanized as Pusan before 2000, is South Korea's second most-populous city after Seoul, with a population of approximately 3.6 million. The population of the metropolitan area, including the adjacent cities of Gimhae and Yangsan, is approximately 4.6 million. The city is located on the southeastern-most tip of the Korean peninsula. - The Gyeongbu Line ("Gyeongbuseon") is the most important railway line in South Korea and one of the oldest. Constructed in 1905, connecting Seoul to Suwon, Daejeon, Daegu, and Busan. The Gyeongbu Line is by far the most heavily travelled rail line in South Korea. High-speed, express, local, and freight trains provide frequent service along its entire length. - Ulsan Station ( Tongdosa ) is a South Korean high - speed rail station located in Samnam - myeon , Ulju - gun . It is on Gyeongbu High Speed Railway and named Ulsan Station with subname Tongdosa , which is located in Yangsan , nearer than downtown Ulsan from the station . The existing Ulsan Station in Samsan - Dong , Nam - gu has been renamed to Taehwagang Station . - Taehwagang Station, meaning Taehwa River Station, is a train station located in Samsan-dong, Nam-gu, Ulsan. It was previously named Ulsan Station until the KTX Ulsan station opened on November 1, 2010. - The Gyeongbu High Speed Railway (Gyeongbu HSR) between Seoul and Busan is South Korea's first high-speed rail line. KTX high-speed trains operate three sections of the line: on April 1, 2004, the first between a junction near Geumcheon-gu Office Station, Seoul and a junction at Daejeonjochajang Station north of Daejeon, and a second between a junction at Okcheon Station, southeast of Daejeon, and a junction near Jicheon Station, north of Daegu entered service; then on November 1, 2010, the third section, between a junction west of Daegu and Busan became operational. The missing gaps across the urban areas of Daejeon and Daegu were opened in August 2015, and separate tracks into Seoul Station are planned. The temporary ends of the north and south sections are connected to the parallel conventional Gyeongbu Line by tracks that will serve as interconnector branches upon the completion of the entire line. - High-speed rail is a type of rail transport that operates significantly faster than traditional rail traffic, using an integrated system of specialized rolling stock and dedicated tracks. While there is no single standard that applies worldwide, new lines in excess of and existing lines in excess of are widely considered to be high-speed, with some extending the definition to include lower speeds in areas for which these speeds still represent significant improvements. The first such system began operations in Japan in 1964 and was widely known as the bullet train. High-speed trains normally operate on standard gauge tracks of continuously welded rail on grade-separated right-of-way that incorporates a large turning radius in its design. - Daejeon is South Korea's fifth-largest metropolis. Daejeon had a population of over 1.5 million in 2010. Located in the center of South Korea, Daejeon serves as a hub of transportation and is at the crossroads of major transport routes. The capital Seoul is about 50 minutes away by high-speed train. What is the relationship between 'ulsan station' and '2010'?
