The line begins in the Linping district of Hangzhou at the
Linpingnan Railway Station metro station, which connects the line to
Line 9 (formerly the Linping branch of
Line 1) of the
Hangzhou Metro and is the only place on the line where passengers can transfer to the Hangzhou Metro. The line starts underground in its first tunnel (out of three tunnels) parallel to the
Shanghai-Hangzhou high-speed railway and proceeds eastward underground, where it surfaces and rises to a viaduct before reaching Xucun station. The line continues eastward, continuing to parallel the Shanghai-Hangzhou high-speed railway, until it reaches
Hainingxi Railway Station, where passengers can transfer to the high-speed rail station of the same name, which parallels the Hangzhou-Haining Intercity Rail station. Past Hainingxi Railway Station, the line enters its second tunnel, where it curves away from the Shanghai-Hangzhou high-speed railway. The line then rises back to a viaduct and reaches the town of
Chang'an and makes several stops there. Past Chang'an, the line reaches Zhouwangmiao station, which contains the first of the line's two passing loops for express trains. The train travels through the rural countryside until it reaches Yanguan station, located north of the Yanguan Town Tide-Viewing Park. The line then passes by the Yanguan Depot, located north of the tracks, which stores and maintains the fleet of trains used on the line, and Tongjiu Highway station, a station at a road that leads northwards to
Tongxiang. At Xieqiao station, the line reaches its second and final passing loop for express trains. Arriving in downtown Haining, the line descends into its third and final tunnel, making three final stops at Leather City, Haichang Road, and International Campus, ZJU, all three of which are located underground. The tail tracks, which are used for reversing trains, extend a couple hundred metres past International Campus, ZJU station, ending just before reaching
the station's namesake campus. The line does not share tracks with any other line, and its trackage is completely isolated from the Hangzhou Metro and the national railway system.
Westward extension A 1.02 kilometre westward extension past the Linpingnan Railway Station metro station to Wenzheng Street station is in progress. ==Stations==
