Harbin
Harbin got its first metro line in 2013, when Line 1 opened. Its trains were built for local winters, when January and February temperatures hover around minus 30°C. In the years since, the network has grown from a single line between Harbin East and Harbin South stations into three lines. Line 2, opened in 2021, tunnels under the Songhua River in just over three minutes, connecting the north bank to the city center, and in November 2024 Line 3 closed its loop, becoming China's first loop metro line in a high-latitude, severe-cold region.
