高鐵公司的回應:
Q1 關於地震應變
ALLEGATIONS
高鐵公司採用的歐洲行控技術，地震發生時，軌道上的偵測器會先透過列車將訊息傳回行
控中心，再由行控中心人員發出應變指令。
但地處地震帶的日本，為爭取時效，是直接由列車下煞車決定，根據新幹線的標準，地震
發生三秒內，高鐵列車就必須完全煞住，不久前發生在日本新瀉縣的經驗，列車是在兩秒
內完成應變動作，但台灣高鐵目前的設計，無法達到這個標準。
THSRC signaling system is based on the European standard. The earthquake signal
is transmitted from the sensor on track to OCC, and the OCC dispatches the
emergency handling command to the trains.
In Japan the decision to engage the emergency brake is made on the train to
save time. According to the Shinkansen’s regulation, the train brakes have to
be engaged within 3 sec. of when the earthquake signal is triggered. With the
recent earthquake incident in Niigaga, Japan, the responce time for the train
was within 2 sec.. Current THSRC design does not reach this standard.
FACTS and CORRECTIONS
1. In our system requirements, the earthquake signal is not sent back to the OCC for “processing”. There is no looping of sending the distress earthquake signal to OCC and have OCC staff issue an emergency brake command.
2. The earthquake signal automated transmission is included as part of THSRC signal system design. When triggered, it will cause the train to initiate an immediate and forceful emergency stop.
3. THSRC's design response time when earthquake signal is triggered is 0.5sec.
4. Shinkasen’s system design initiates the emergency stop command within 3 seconds. This does not refer to the total brake time required to come to a complete stop.
Further Info on the earthquake signal design
‧ Shinkansen triggers the emergency stop through the power supply system.
‧ THSRC triggers the emergency stop through the signaling system.
