How does the Wenhu Line of the Taipei Metro respond to an earthquake?

In the event of an earthquake:
If the train is docked at a platform inside a station, service will be suspended. If the train is between stations, it will decelerate until it comes to a stop.
The Operation Control Center (OCC) will immediately collect information and evaluate the impact of the earthquake.

1. If the earthquake measures less than 2 on the Richter scale and no anomalies have been detected, system operations will return to normal.

2. If the earthquake measures 2 or 3, train speed is reduced by 50%. The OCC will check for equipment warnings and ask staff to check track status. If all  summary reports are normal, system operations will return to normal.

3. If the earthquake measures 4 or above:
(1) If a train is at station, passengers are evacuated immediately.
(2) If a train is between stations, one of the following two options should be chosen:
a. If the earthquake measures 4, the train will stop and the system will be inspected. If no damage or malfunction is detected, trains with personnel on duty will continue in full-manual mode to check the track status at 5 km/h or under; passengers will be evacuated at the nearest station. For trains without personnel on duty, the station master of the upcoming station will walk out to the train to inspect the tracks. If track conditions look normal, the train may proceed in full-manual mode to the next station, where all passengers will be evacuated.
b. If the earthquake measures 5 or above, the train will stop and the system will be inspected. Trains in underground sections may continue in full-manual mode to view the track status at a speed of 5 km/h or under, and passengers will be evacuated at the nearest station. For trains between stations, the station master of the upcoming station will walk out to the train to inspect the tracks. If track conditions look normal, the train may proceed in full-manual mode to the station, where all passengers will be evacuated.
(3) After all passengers are evacuated, the system and all traction power will be shut down. Maintenance staff and station staff will begin to check all structures, tracks, and equipment.
