A crack in the track on the Tsuen Wan Line led to delays of up to 15 minutes yesterday in the second such incident on the same section in six months. The crack was found in a section of track from Lai King toward Kwai Fong at 10.40am, causing MTR trains to operate at lower speeds. The section of track, which is outdoors instead of under cover, was also found cracked in May. Trains from Central to Tsuen Wan took 10 to 15 minutes longer than usual for more than two hours. Trains using the line were running at six-minute intervals until services returned to normal at around 1.30pm.

 

According to the website of MTR Corp Ltd, the crack was temporarily secured by an additional plate at around 1.15pm. Temporary arrangements were made so passengers on some trains heading toward Central got off at Admiralty and waited for the next services.

 

In a Facebook page called MTR Service Update, one netizen posted: "Luckily this did not happen during rush hour." Another one slammed the MTRCL: "The sincerity of their apology was definitely reflected through fare increases." The crack was found after a driver reported an abnormal vibration at around 10am.

 

An MTRCL spokeswoman said: "The crack was very small. It was less than one millimeter wide." She said the company would replace the section of track and try to find out what caused it to crack. It was safe for the services to keep running because rails are securely fastened onto track support structures with steelclips located every 0.61 of a meter apart to avoid displacement. The temporary measure of adding a plate to the crack would guarantee stability for train services before workmen fixed the problem at night.

 

The spokeswoman said the section was last inspected by an advanced ultrasonic testing vehicle at midnight Saturday. It was visually inspected at midnight Sunday. The vehicle was purchased for HK$46 million by the MTRCL two years ago in order to monitor and maintain track conditions. Engineer Lo Kok-keung said the track may come under more pressure than other sections along the line because it happens to be on a bend. Lo said cracks in the track are a normal phenomenon but they should not happen too often. "Weather changes, long-term usage of the rail and metal deterioration may cause cracks," he said. Lo suggests the MTRCL pay extra attention when inspecting tracks on bends because they are likely to be more prone to cracks. A total of three track cracking incidents have been recorded so far this year compared to three for the whole of last year.

Why did they just repair the crack instead of going with a temporary fix? They should have either replaced the broken section or fix properly that way it wouldn't crack again.

I gather they will be fixing the cracks now. Things break it's only natural. But I agree, maintenance of the tracks needs to be more thorough. One slip up could cost a lot of lives.
