Line 17 (Beijing Subway)

Line 17 is planned to run from the Future Science Park North station in Changping District to Yizhuang Zhanqianqu South station in Tongzhou District.[7][8] The line is fully underground with a total length of 49.7 km (30.9 mi).[9][8] The expected end to end travel time to be approximately 56 minutes.[10] When complete, the line will provide relief to the congestion on Line 5, Line 10 and Line 13.[10]

Line 17 will use 8-car Type A rolling stock.[5]

In January 2011, an official with the city's planning committee indicated that Line 17 of the subway was planned to run east–west through the city's Central Business District under Guanghua Road with transfers to Lines 4 and 5.[12] However, the line run through Central Business District is known as Line 28 now.

In February 2012, the city's planning committee identified a different Line 17, as a line planned for 2020, that would run north–south from Tiantongyuan to Yizhuang that would run parallel and to the east of Line 5.[13] On June 15, 2012, the city government disclosed tentatively planned stations for the line.[14][7][15][8]

On October 10, 2013, city authorities confirmed that Line 17 would run from the Future Science Park North station in Changping District to Yizhuang Zhanqianqu South station in Tongzhou District.[8] Construction was expected to begin in 2014 and Line 17 would have a total length of 49.7 km (30.9 mi).[8]

Construction of the line began in 2015.[16][17]
