Busan Metro Line 2

Busan Metro Line 2 (2호선) is a line of the Busan Metro that crosses Busan, South Korea, from east to west, running along the shores of Haeundae and Gwanganli, and then north toward Yangsan. It is represented by a green colour. It has the highest ratio of subterranean stations to elevated stations, with only its last six (originally last two before Jeungsan, the Pusan National University Yangsan Campus station, Namyangsan, and Yangsan station were built and opened) being elevated and the first 37 being subterranean. The line is 45.6 km long with 44 stations, and its trains have six cars each.

Line 2's station signs have lime-green frames, using the same design as Line 1's station signs for the inner walls. On the outer walls, the signs have two arms sprouting from their sides, but have the same round face with the Hangul name of the station printed in big font and the English and Hanja names printed beneath in descending order in small font with the station number beside the English name. The arms have the names of the neighboring stations (in the aforementioned three fonts) and their ends are flat. Due to the fact that the trains drive on the right side, the left arm of each sign has the next station appropriate to the train on the same side and the right arm has the previous station. Additionally, an arrow can be seen on the left arm pointing in the direction of the next station. Line 2 is the first line through the line to have station signs that have arms on the outer walls, although Line 1 will receive station signs with arms in certain stations such as Seomyeon.

A ride through the entire line takes about 1 hour 24 minutes. Busan Metro Line 2 will be expanded from Jangsan Station to East Busan Tourism Complex in Gijang County which will be opened in 2021. (Currently Planned)

History
Plans to create the line began in 1987 and were finalized by 1991. During the construction of the third section of the line in 2001, the original plan to extend the route three stations beyond Yangsan Station was scrapped at the request of the citizens of Yangsan, with a new light rail line currently undergoing approval as an alternative.

An older plan hoped to stretch the line four stations beyond Jangsan Station, but was scrapped due to cost concerns. The extension idea has gained new interest, but with proposals for a new light rail line connecting Jangsan Station to the city of Ulsan.
