The Land Transport Authority has been working closely with train manufacturer, Kawasaki Heavy Industries & CSR Sifang, on defects that were found on trains purchased under C151A. These defects, found on the train body, are not safety-critical and do not affect the train’s systems or performance. The train manufacturer will be required to make good the defects as part of their warranty.
Trains on the rail network are extensively tested to ensure the safety and reliability of the train. Every train also undergoes a comprehensive regime of static and dynamic testing as well as interface testing to ensure its structural and operational integrity. After the testing is completed, the trains are delivered to Singapore for further testing before they are placed for passenger service.
