Beijing–Shanghai high-speed train

The Beijing–Shanghai high-speed train (京沪高速动车组列车) are high-speed train services operated by CR Beijing and CR Shanghai on Beijing–Shanghai HSR in China. The services provide high-speed train connections between Beijing, the capital of China, and Shanghai, the economic center and largest city of the country. Currently, 41 pairs of G-series trains are operated daily.

History
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. 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 The day-time D-series trains were finally withdrawn from the service on 10 December 2014, with the D316 being upgraded to G412. 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.
