D trains (动车组; Dongchezu) in China Railways are HSR trains running between regional centres, or are lower-speed national HSR services. As a rule, no D train will run faster than 250 km/h (157 mph), and as they often make lots of stops at regional stations, they’re generally considered regional services.
The following train numbers are in use:
- D1 – D4998: Long-distance D trains
Please note that trains with numbers between D4001 and D4998 are usually extra services.
- D5001 – D9998: Regional D trains
Please note that trains with numbers between D9001 and D9998 are usually extra services.
