Trams
The first tram line in Seoul started operation between Seodaemun and Cheongnyangni in December 1898. The network was expanded to cover the whole downtown area (Jung-gu and Jongno-gu districts) as well as surrounding neighbourhoods, including Cheongnyangni in the east, Mapo-gu in the west, and Noryangjin across the Han River to the south.
The networks reached its peak in 1941, but was abandoned in favor of cars and the development of a subway system in 1968. Seoul Subway Line 1 and Line 2 follow the old streetcar routes along Jongno and Euljiro, respectively.
