What are the causes of the high-speed train rear-end collision accident?

Below is the relevant introduction to the causes of the high-speed train rear-end collision accident: Management chaos: The Signal & Communication Research & Design Institute under China Railway Signal & Communication Corporation (CRSC) had chaotic management during the R&D of the LKD2-T1 train control center equipment. As the general contractor for the communication and signal integration of the Yongtaiwen Line, CRSC failed to fulfill its duties effectively, resulting in the LKD2-T1 train control center equipment provided for Wenzhou South Station on the Yongtaiwen Line having serious design defects and major safety hazards. Violation of regulations: The former Ministry of Railways violated regulations in the bidding, technical review, and operational use of the LKD2-T1 train control center equipment, with inadequate supervision, leading to its operational use at Wenzhou South Station. When the fuse F2 in the power circuit of the data acquisition unit of the train control center at Wenzhou South Station was melted due to a lightning strike, the acquisition data was no longer updated, erroneously controlling the track circuit coding and signal display, placing train operations in an unsafe state.
I think high-speed train rear-end collisions are often attributed to several key points. As someone who frequently follows rail transportation, the primary issue is signal system failure, such as lightning strikes causing signal equipment malfunctions, preventing the trailing train from promptly identifying the position of the leading train. Secondly, human factors like dispatcher misjudgment or driver fatigue can compound risks, especially in severe weather when drivers' reactions may slow down. Aging equipment is also a hidden danger, as brake system failures or improper maintenance can extend stopping distances. From my experience, prevention requires strengthening automated systems, conducting regular personnel training, and society-wide efforts to enhance safety awareness to avoid a repeat of incidents like the Wenzhou accident. Overall, the combination of technical and human vulnerabilities is the main cause, and safety improvements cannot be taken lightly.
