The CRH services between Beijing and Shanghai dates back to the sixth national railway speedup implemented on 18 April 2007, when the D31/32 trains began operation on the Beijing–Shanghai railway. The D32 train had a service time of 9h 59m, which was 2 hours shorter than the Z-series trains, and became the fastest train service between Beijing and Shanghai at that time.[1] One more pair of trains were added to the service on 1 December 2009, under the train numbers D29/30.

On 18 April 2008, one year after the introduction of D-series trains, the Beijing–Shanghai HSR commenced construction. The HSR was inaugurated on 30 June 2011, with the faster G-series trains started operation on it. Some D-series train services were still kept, but were switched to operate on the new HSR. The day-time D-series trains were finally withdrawn from the service on 10 December 2014, with the D316 being upgraded to G412.[2] The night-time D-series sleeper train services remain in operation.

On 26 June 2017, the China Standardized Fuxing EMUs made the debut commercial operation on this service.[3][4]

G1-18 and G21/22 are faster services with fewer stops, with an average travelling time of about 4h 30m. G101-160 and G411/412 are services with more intermediate stops, and the travelling time varies from 5h 22m to 6h 24m.
