Busan Metro Line 3 (Korean: [[:ko:부산 도시철도 3호선|3호선]]) is a line of the Busan Metro system. It was built from 1997 to 2005 and opened on November 28, 2005. The line is 18.3km (11.4miles) long, and has 17 stations, and its main colour is brown. Each train of the line has 4 cars. Line 3's trains have an open gangway between each car (just like Line 4), giving an unblocked view of the whole train from one end to the other. The line was originally planned to have a main line from Suyeong station to Daejeo station with a second phase that splits from Minam Station. However, the second phase split into a separate line and is now called Line 4.
Line 3's station signs use a similar design to those Line 2, with the station name written in Hangul at the top in big letters and English and Hanja near the bottom in small font. However, Line 3's station signs have different colours for their border and arms, with the top half being brown and the bottom half being grey. The arms also have differing designs for their respective neighboring stations, with the arm pointing to the next station having a tipped end and the arm pointing to the preceding station having a concave indent; the Hangul name is printed in the brown half while the grey half houses the English and Hanja names. The current station's number is also printed close to the top, above the Hangul name. Some stations, like Suyeong, however, have shifted to putting the number next to the English name with a solid brown colour for both the arms and frame, keeping the same end designs while putting the English and Hanja names next to the Hangul name, closer to the sign's main body.
Due to the Daegu Subway Fire in 2003, all of Line 3's stations were built with platform screen doors. Line 3 was one of the first metro lines in both Korea and the world to have platform screen doors equipped at every station.
Line 3 greatly increased the efficiency of the entire Busan Metro system. While Line 2 connects the Deokcheon region to the Suyeong region in a rather curved, 'southernly' way, Line 3 connects the two areas in a more straight line. For example, a person living in the Yangsan area would not use the whole line 2 to reach the Haeundae area; instead, he or she would transfer at Deokcheon Station to Line 3, and transfer back to Line 2 at Suyeong Station. Line 3 also increased the efficiency of traveling between Deokcheon and Yeonsandong area, along with the Minam and Dongnae area.
A ride through the entire line takes about 34 minutes.
All stations are in Busan.
