How long does it usually take for the high-speed rail joint debugging test?

Legal analysis: the line of sight is about 60 days to 120 days. For the safety of high-speed rail operation, the joint debugging and testing is actually quite complicated. From cold sliding to hot sliding, to comprehensive inspection of locomotives, to actual operation inspection of vehicles, and finally placing heavy objects such as rice to simulate load operation, this process is very detailed. The whole debugging test takes 2-4 months and is divided into 5 stages.

Legal basis: People's Republic of China (PRC) Railway Law.
