Line 5 of the Guangzhou Metro runs from Liwan District to Huangpu District. It starts at Jiaokou running 41.7 km (25.91 mi) in a wide "∩" shape and ends at Huangpu New Port. Like lines 4 and 6, it is equipped with linear induction motor technology. Line 5's color is red. Line 5 began operation on 28 December 2009, from Jiaokou to Wenchong.[4] On December 31, 2009, Line 5 set a record of 567,000 daily passengers, surpassing the ten year ridership projections in the span of just 4 days after its opening. As of May 2017, Line 5 carries an average of 1.05 million passengers per day and is extremely congested throughout the day, operating at over 100% capacity during rush hours.[5][6] The opening of Phase I of Line 13 further increased traffic demand on the west end of Line 5 and pushing congestion to over 130% capacity.[7] Prompting the Guangzhou Metro to limit passenger traffic at a number of subway stations on Line 5.[7] In 2018, the busiest section of Line 5 reaches over 50,000 pphpd of traffic volume during peak periods.[8] By 2019, the line was used by 1.18 million passengers each day.[2] In the future Line 13 Phase II will provide relief for Line 5. On 28 December 2023, the line was extended to the east from Wenchong to Huangpu New Port.[9]
Line 5 uses six car linear motor trains. In 2020, Guangzhou Metro started bidding for 14 additional trains to supplement the fleet in preparation for the east extension.[10]
