In the following article, “Trains on the North-South and East West Lines Safe for Service”, Land Transport Authority (2016) addresses the problems that it faced in regards to the North-South and East-West lines trains. It also states the actions taken to resolve the problems and how trains were subjected to tests to ensure their safeness and reliability. The webpage mentioned that complications were found on trains whereby the battery housing flew open due to pressure. Not only that, cracks were also found on the draughtscreen of five trains which were due to errors during the installation process. However, operations of train services were not affected as these problems were rectified immediately. LTA reported that hairline cracks were also found on 26 of the train’s car-body shell which was caused during production period. As it is impossible to repair the cracks, affected trains that were under warranty were sent back for replacement of parts at no costs. With a view to complete the rectification programme, LTA expressed that they will send two trains at a time for servicing. Nevertheless, this is dependent on the arrival of new trains along with the current ones which are undergoing resignalling. Lastly, in order to ensure the safety and efficiency of the services, LTA concluded that they will work closely with the contractors and SMRT. However, there is some lack of information regarding the hairline cracks. As to why more than half of the trains were found with the cracks in just a routine check, whether there is any level of severity to be considered a hairline crack. How will they prevent or minimize it, and understanding that even with the crack, it is still fit and safe to operate, so why do we need to replace it.
