It runs from Anheqiao North in the north and ends at Gongyixiqiao in the south, but the 4-Daxing connected line runs all the way to Tiangongyuan in Daxing. All stations are underground except Anheqiao North. It is 28.2 km (17.523 mi)^[6] long with 24 stations.^[7] Riding on this line starts from a fare of RMB(¥) 3.00 depending on the distance traveled.

Line 4 and the Daxing line operate as a single line through-running onto each other although they are classified as separate lines.^[8] Two different services are run during the day: A full service covering both Line 4 and the Daxing line, and a shorter service that ends at Xin'gong station, the first station of the Daxing line. Combined, the Line 4/Daxing Line Corridor carries an average of 1.24 million passengers every day in 2017,^[9] growing to about 1.4 million passengers per day by 2019.^[10]
