The Chinese trains, on the other hand, had to be shipped back and according to FactWire, the whole aluminum body of the train cars have to be discarded and the Chinese partner, Japan's Kawasaki Heavy Industries, has made a decision to take over the manufacturing of the train auto body from the Chinese, leaving the Chinese to be only responsible for the assembly of the train parts.
As the trains were still under the manufacturer's warranty, LTA chose to send them back for rectification.
The alarm bells were raised as online news platform FactWire reported that the mainland Chinese-made trains in Singapore had cracks in their bodies and key structural components. Most of the trains were to be delivered between 2011 and 2012.
The Singapore Land Transport Authority also told Channel NewsAsia that the cracks "are not safety-critical and do not affect the train's systems or performance". Of the 26 trains found with defects, 22 had been put into service.
In its Facebook posting, the party noted that many Singaporeans have been surprised at the revelation of defects in some of the trains used by the MRT, leading to 26 of these trains being shipped to China for fix or replacement. CSR Sifang staff confirmed to reporters that the train had arrived at the factory on June 25 from Singapore, and the reporters themselves verified this independently after seeing the trains wrapped in the same covering with similar markings as well.
MP for Aljunied Muhamad Faisal Abdul Manap: To ask the Minister for Transport whether members of the PTC, Board members of SMRT and the LTA and the management of Temasek Holdings were aware of both (a) the faults being discovered on trains supplied to the LTA by Kawasaki Heavy Industries and CSR Sifang in 2013; and (b) the subsequent train recall exercise.
Also, those minor cracks found on the LRT trains were only developed after 16 years in operation.
He added that they have been closely working with the Land Transport Authority and the manufacturer.
Hairline cracks found on the China-made MRT trains were due to localized impurity in aluminium car-body material that occurred during manufacturing process.
"The defective trains, which are still under warranty, will be repaired by the manufacturer".
LTA engineers and its contractor, as well as an independent third-party assessor TUV Rheinland, concluded after tests that the cracks would not affect the operational safety of the trains, said LTA. The car-body replacement for five of the 26 trains has been completed so far.
"CRRC Sifang found some defects in vehicle bodies during routine maintenance checks in Singapore in June 2013". This will speed up the rectification programme and its completion can be brought forward to 2019. As per safety protocols, LTA, together with the contractor, will continue to carry out rigorous inspections to ensure that all trains are safe for service.
