There were 408 serious accidents with 50 deaths on the Taroko railway. It was preliminarily determined that the cause of the accident was that the grade engineering vehicle did not apply the parking brake and the vehicle slipped on the rails. Another point of controversy is why there is no guardrail on the slope of the road section. Coincidentally, the actual investigation found that the construction vehicle construction project design and manufacturing supervision unit and the Houdong landslide slope monitoring company last year were both United Earth Engineering Consulting Company.
To our understanding, the case carried out by the engineering vehicle slipping on the rails is the “Six-Year Rail Safety Improvement Plan-North Loop” contracted by the Taiwan Railway Works Department. K51 + 170 ~ 500 slope protection installations are expected to be carried out. The unit responsible for design and manufacturing supervision is United Earth Engineering Consulting Company.
In fact, Lianhe Dadi is also in charge of the Houdong Slope Inspection Company. The Houdong landslide on December 4 last year caused a complete disruption of Yilan County’s east-west main line for 10 days. It was not until the 14th that the single track operation was resumed.
Slope protection management is divided into four levels: A, B, C and D. They are A. The slope shows obvious signs of instability, which can affect the passage of trains. The necessary reinforcement measures and patrolling and close monitoring must be taken. ; B, suspected stability signals that may affect train traffic. In addition to strengthening measures, it is necessary to strengthen monitoring; C, no obvious signs of instability, routine maintenance, patrol monitoring; D, slope stability, lift the tube.
After several days of heavy rain causing the Houdong landslide, Lianhe Dadi was questioned by all parties that the slope detection was inaccurate and only classified the site as Class C with no “obvious signs of instability”. In response, Lianhe Dadi issued a statement to clarify that an abnormal condition was found in the Houdong Zaoshan section on November 30. After being notified by the Taiwan Railways, it immediately dispatched personnel to the site to block the Xizheng Line and take reinforcement measures and 24-hour monitoring. It rained heavily for several days. On the morning of the 4th, the monitoring staff of the Taiwan Railways discovered that there was an obvious anomaly and urgently notified the train to stop slowly. Upon receiving the notice, the company rushed to the scene to assist with on-site management, and provided relevant assistance in the follow-up. He also humbly accepted outside advice.
More than 14 hours have passed since Taroko’s accident occurred. It has been preliminarily determined that the grade engineering vehicle did not apply the parking brake, causing the vehicle to slip on the rails and cause an accident. However, the detailed cause and responsibility of the accident has not yet been clarified. In-depth investigation.
