G trains (高速动车组; Gaosu Dongchezu) in China Railways form the bulk of fast HSR services running across the nation. They are China’s fastest and most state-of-the-art trains, and are found on a great number of new high speed lines. Train sets on G services have been built to run at up to 380 km/h (237 mph), although most run at the temporary speed limit of 300 km/h (186 mph). Nearly all lines with G train services have been designed for speeds of at least 350 km/h (217 mph).
G trains always feature First and Second Class, and usually feature Business Class, which has slumberettes.
The following train numbers are in use:
- G1 – G4998: Long-distance G trains
Please note that trains with numbers between G4001 and G4998 are usually extra services.
- G5001 – G9998: Regional G trains
Please note that trains with numbers between G9001 and G9998 are usually extra services.
The fastest G trains are trains G1 to G4, which complete the entire 1,318 km (824 mi) sprint between Beijing and Shanghai in just 4 hours and 48 minutes.
