In recent days, the Harbin Railway Maintenance Section has been rigorously guarding against the safety risks posed to railway transportation by low temperatures and extreme cold. It has been strictly adhering to standardized operations and making every effort to firmly grasp the control of current safety. It ensures the safety and smoothness of the lines under its jurisdiction and lays a solid foundation for the upcoming Spring Festival travel rush.
