The Harbin–Dalian high-speed train (Chinese: 哈大高速动车组列车) are high-speed train services between Harbin, the capital of Heilongjiang Province, and Dalian, a major city in Liaoning Province.

The high-speed train services between Harbin and Dalian were commenced on 21 April 2013, with the inauguration of the Harbin–Dalian HSR.

[1] At the initial stage, the timetables of the services were different in summer and winter due to climate factors.

The summer timetable was effective from 21 April to 30 November, during which the G-series trains with a higher speed were operated.

Trains are operated at a speed of 300 kilometres per hour (190 mph) throughout the year.
