The Guangzhou Rail Transit Line 3 vehicle project is a B-type vehicle project independently developed and manufactured by CRRC CSR. The entire project is 26 columns, 6 sections (4 sections of trains, 2 sections of trailers), a total of 156 vehicles. Adopt DC1500V overhead rigid contact net to receive flow; B-type aluminum alloy body; bogie is independently developed by the company, namely ZMA120 high-speed B-type bogie. The vehicle has a top speed of 120km/h and a construction speed of 135km/h. At present, the CRRC car in the Guangzhou area has successively obtained the 128th, 28th, Guangfo, 7th, 9th, 14th, 18th, and 21st lines in Guangzhou. Train orders for subway projects.
