Taipei Rapid Transit Corporation ─ Metro Service

In the event of an earthquake measuring over 2 in intensity, service will be suspended if a train is docked at a platform inside a station. If a train is between stations, it will decelerate until it comes to a stop.

The Operation Control Center (OCC) will immediately gather information on the earthquake, evaluate its impact on the metro system, and determine which of the following measures to adopt:

1. If the earthquake intensity was 2 or 3, on the high-capacity system the train operator will switch to code-manual mode and proceed at a speed of 40 km/h or under while conducting a track inspection. On the Wenhu Line, the OCC will reduce train speed to 50% of the speed limit. If inspections do not uncover any abnormalities, system operations will return to normal.

2. If the earthquake intensity was 4 or 5 and peak ground acceleration is ≦100 gal, the train will advance to the next station at a low speed to evacuate passengers. Then, on the high-capacity system the train operator will switch to code-manual mode and proceed at a speed of 15 km/h or under while conducting a track inspection. On the Wenhu Line, the OCC will ask staff to board the train and inspect the tracks while the train proceeds at 25% of the speed limit. If inspections do not uncover any abnormalities, system operations will return to normal.

3. If the earthquake intensity was 5 and peak ground acceleration is >100 gal, staff will walk out to the train to inspect the tracks, and the train will slowly advance to the next station to evacuate passengers. System operations will then be suspended temporarily. After all passengers are evacuated, staff will walk down the track to inspect the track. When the track inspection is completed, on the high-capacity system the train operator will switch to code-manual mode and proceed at a speed of 25 km/h while conducting a track inspection. On the Wenhu Line, the OCC will ask staff to board the train and inspect the tracks while the train proceeds at 50% of the speed limit. If inspections do not uncover any abnormalities, system operations will return to normal.
