On the North-South MRT line breakdown

I am reposting the statement made by Singapore's Transport Minister Lui Tuck Yew on Channel News Asia online:

[Writing in his Facebook, Transport Minister Lui Tuck Yew said: "I have been following the incident of the MRT breakdown from Cambodia. I am especially concerned over the well-being of the people who were reported to be trapped in the trains for an extended period of time before they made their way to safety.

"There have been a number of train disruptions in recent days. I do not know if these are isolated incidents or whether there are systemic and more serious underlying issues causing these breakdowns.

"We will therefore conduct a thorough health check on our train systems, determine how the faults happened and also whether the maintenance, communication and recovery processes were adhered to and can be further improved.

"I have asked LTA to assemble a team of relevant experts, including possibly relevant overseas experts (emphasis added) to help us in this review." ]

I am curious to know if possibly overseas experts would know what is wrong with the possibly systematic breakdowns of Singapore's proudly acclaimed world class train transport network. If something breaks down in the company, it might just simply mean someone in th SMRT is blungeing on the job. Simple. Why do u need a foreigner to tell you what is wrong with your family? You dun trust your staff to tell you what is wrong?
