The bullet trains can run at a maximum speed of 350 km per hour, but for the frosty initial stage, they will travel with caution at slower speeds, according to the Ministry of Railways.
The speed between Dec 1 and March 31 will be 200 km per hour, and for the rest of the year it will be 300 km per hour. The ticket prices will vary based on the speeds.
Lu Hongguang, a white-collar worker in Harbin, said: "I am quite impressed after seeing how modernized and advanced the line and the train are."
With the Harbin-Dalian railway, the regions' cargo capabilities are hugely increased, the Ministry of Railways said.
Construction for the Harbin-Dalian line began in August 2007 with a total investment of 92.3 billion yuan ($14.8 billion). It is part of the planned Beijing-Harbin high-speed railway.
