Why has the Jiamustong-Hegang high-speed railway been delayed in opening to traffic?

The reason why the Jiamustong-Hegang high-speed railway has not been opened to traffic is that the railway has not been repaired. According to relevant public information, the Jiahe High-speed Railway will be officially opened in February 2023. Heilongjiang Province Jiahe Railway Renovation Project, also called Jiahe Express Railway, is a rapid railway from Jiamusi City to Hegang City, including the reconstruction of existing railway sections and the construction of new sections.
