Daegu Line 3's 'electrical control device' malfunctions this time... Repeated delayed response (comprehensive)

A series of breakdowns and failures occurred on Daegu Urban Railway Line 3, causing continued inconvenience and anxiety to citizens. The breakdown that occurred on the 7th was found to have originated from the 'electrical control device'.

There was a train delay due to a breakdown the previous day, but it is pointed out that the safety information text was sent out 30 minutes after the breakdown, and that citizen guidance was once again late.

According to Daegu City on the 8th, the suspension of operations on Daegu Metro Line 3, which occurred the previous day, began when the vehicle's electrical control system failed.

The electrical control device is a device that supplies electricity to the vehicle. At the time of the malfunction, the device failed for an unknown reason and electricity was cut off to the vehicle.

At the time, it was confirmed that the vehicle's emergency generator was activated and the interior lights of the vehicle were activated, but the electricity was not generated enough to operate the vehicle.

The vehicle is currently in storage at Beommul Vehicle Base, and the exact cause of the failure is being investigated.

The authorities plan to conduct a full investigation of the relevant parts.

On Daegu Metro Line 3, train operations were delayed in all sections due to a vehicle breakdown between Jisan and Beommul Station at 2:24 p.m. the previous day, but operations were normalized after about 30 minutes.

Daegu Transportation Corporation notified citizens of the delay in train operation and normalization measures due to the train breakdown through a safety information text message after the breakdown, but only sent out the text message 30 minutes after the breakdown occurred.

Previously, in the event of a service interruption accident on September 7, it was pointed out that the citizen response was delayed as the information was not sent until about 50 minutes later.

Although this accident was recovered relatively quickly, civil unrest is increasing due to three breakdowns and failures in about two months.

Daegu Metro Line 3 previously had a problem with the track switch that moves trains arriving at Yongji Station to the upbound line on the 2nd, disrupting train operations on the way to work, but was restored in 16 minutes.

On the evening of September 7, the lightning protection facility between Suseong-gu Citizens' Stadium Station on Line 3 and Yongji Station caught fire, causing a power supply failure in the entire section, leading to suspension of operation for the entire section, but resumed after about three hours.

A Daegu city official said, "It would be hasty to say that (recent series of breakdowns and failures) have occurred more frequently than before," but added, "As citizens are anxious, we plan to review with the Daegu Transportation Corporation the formation of special measures and a dedicated organization."
