The "fastest" train commercial service can be defined alternatively by a train's top speed or average trip speed.
The fastest train service measured by peak operational speed is the Shanghai Maglev Train which can reach 431 km/h (268 mph). Due to the limited length of the Shanghai Maglev track (30 km)(18.6 mi), the maglev train's average trip speed is only 245.5 km/h (152.5 mph). The Shanghai Maglev also holds the record for the top speed in tests of 501 km/h (311 mph).
The fastest train service measured by average trip speed is on the Wuhan-Guangzhou High-Speed Railway, where the CRH3/CRH2 coupled-train sets average 312.5 km/h (194.2 mph) on the 922 km (573 mi) route from Wuhan to Guangzhou North. It is the fastest commercial train service in the world.
The top speed attained by a non-maglev train in China is 487.3 km/h (302.8 mph) by a CRH380BL train on the Beijing–Shanghai High-Speed Railway during a testing run on January 10, 2011.
