According to information from Harbin Metro Group, the first electric train on Harbin's metro line 2 began trial operations on Sept 29, marking the start of the project’s final preparation stage. 

The new metro train is a second-generation electric passenger train specially built by CRRC Changchun Rail Vehicles Co for Harbin’s metro system.

Since Harbin's winter temperatures can see the mercury hit a frigid -30 degrees Celsius, the trains operating on metro line 2 have adopted industry-leading cold-resistant technology. This tech ensures that the trains' performance remains stable in low-temperature environments and provides passengers with a comfortable cabin temperature.

The metro trains have a designed maximum speed of 80 kilometers per hour. Metro line 2 has a total length of 28.7 kilometers, with 19 underground stations along the line. Of these, eight stations provide transfers for Harbin’s metro lines 1, 3, 4, 5, 6 and 8.
The first phase of the new metro line 2 has been completed and fine-tuned, and is expected to be put into operation in the second half of 2021.

The metro line will be the backbone of the Harbin rail transit network from the city’s north to southeast, connecting areas along the south and north banks of the Songhua River.

The total investment for metro line 2 is approximately 20.49 billion yuan ($2.93 billion).
