After the Linping branch of Line 1 became part of Line 9, Line 1 now runs fully underground. The line begins at
Xianghu station in
Xiaoshan District, located just north of its namesake lake. Located adjacent to Xianghu station is the Xianghu Stabling Yard, where some of the line's trains are stored and where the metro is headquartered. The line proceeds northwards along Fengqing Avenue, Bin'an Road and Jiangling Road through the central part of
Binjiang District. The line then crosses the
Qiantang River in a tunnel. Upon reaching Shangcheng District on the north side of the Qiantang River, the line passes by the Hangzhou
Public Security Bureau's headquarters and runs for a short distance along Wujiang Road to
Hangzhou Railway Station. It reaches the downtown "U" portion of the line, which is one of the busiest parts of the line, running next the
West Lake Scenic Area along Yan'an Road. The line crosses under the
Grand Canal near the Wulinmen Dock and curves eastward towards
Hangzhoudong Railway Station. Its respective metro station, East Railway Station, is located underneath the arrivals hall of the station. The line continues to proceed eastward along Jiuhe Road, past the Qibao Depot, another depot on the line located adjacent to
Qibao station. At
Coach Center station, the Linping branch of the line formerly branched off from the main line towards
Linping station, but this branch of the line has since become part of
Line 9. Upon reaching
Xiasha Subdistrict, the line runs along Jinsha Avenue and 2nd Street until it reaches
South Wenhai Road station, where passengers can transfer to
Line 8 to continue to the east end of
Qiantang District. The line then curves southwards and runs along 25th Street to
Xiashajiangbin Station, the terminus of short-turn trains (roughly every other train). The line crosses the Qiantang River in a tunnel a second time and returns to
Xiaoshan District. It passes through some low-density areas, crosses under one of the runways of
Hangzhou Xiaoshan International Airport, and finally terminates at
Xiaoshan International Airport station, located among the terminals. ==Service routes==
