The new signal system of the MTR East Rail Line has experienced frequent problems in the past two weeks.

It is reported that the emergency stop indicator (commonly known as "cross light") suddenly lit on an East Rail Line train near the University Station in the afternoon of February 15, causing the train captain to stop the train urgently.

The MTR replied that the "cross light" was not normally lit. About 2 to 3 minutes after the reset, the train captain had drove the train away from the station. Initially, it was believed that it was related to the individual "cross light" parts and did not involve traffic safety.

Someone familiar with the operation of the East Rail Line told "Hong Kong 01" that there are pressure pads near the rails under the platform of the University Station. If someone or foreign objects come into contact with them, they will have the opportunity to trigger the cross lights to light up. The old 12 trucks require the captain to turn on his own Observe the lights of the cross lights and manually stop them; the new 9 trucks will be automatically stopped by the signal system after the lights are turned on.

It is difficult to estimate whether the new signal system is involved because it is unknown which train is involved in the incident.

The media quoted news reports that on February 15 an East Rail train was suspected of pressing the emergency stop switch on the platform, but the new signal system did not respond, and the train near the stop was not controlled.

The MTR denied that someone at the station had pressed the platform emergency switch on that day, and there was no "no response" situation in the new signal system.

In response, the MTR stated that when a train from University Station to Hung Hom was leaving the platform at the time of the incident, the captain saw a cross light turned on and stopped according to the established procedures. It was initially believed that it was related to the parts of the individual cross light. Not involved in driving safety.

A person familiar with the operation of the East Rail said to "Hong Kong 01" that the cross lights were on. In addition to the emergency stop switch on the platform, there are also individual stations on the East Rail Line, including the platform of the University Station. There is pressure pad sensor, if you touch the pressure pad, it will light up, "sometimes it will fail when it rains."

The person continued to point out that in the past, train captains had to pay attention to the lights to brake, and the signal system would not automatically stop the train when the cross lights were on. However, the new 9-car trains cooperated with the new signal system. The signal system will stop the trains within 50 meters of the station.

However, without knowing which train the incident happened, it is difficult to estimate whether the signal system is involved.

After the new signal system of the East Rail Line was put into service, there were repeated reports of problems. "Hong Kong 01" received news earlier that there were still "fake lights" problems in construction vehicles recently, that is, the system misjudged the train lights. The highest test There were as many as 19 misjudgments in one night.

MTR replied yesterday that it admitted that there was a "fake flashing" problem, but did not specifically explain why the same problem still occurred. It only stated that it needs to be run-in and adjusted. Recently, the number of related problems has decreased and it reiterated that it does not affect the safe operation of trains.
