Reader Response (Draft 3)

The Land Transport Authority (LTA) (2016) stated that all trains were gradually sent for servicing and it also conducted severe testing of trains safety as well as dependability. Addressing the battery problems, the news release further explained that the manufacturer fixed it promptly by changing the battery supplier as well as improving the design of the "battery housing". It was stated in the news release that appropriate actions had been taken to get the manufacturer to rectify the draughtscreen problems, which were due to errors during the installation process. The news release also reported that the "hairline cracks" were due to “localized impurity” during the manufacturing process and all these problems would not affect the operational safety of the trains. According to the news release, LTA would return defected trains to the factory in China to exchange the entire "car body shell" and it assured that periodic inspections would be conducted to ensure commuters’ safety. However, I feel that the news release is incomplete as it fails to consider several aspects that may cause defect on trains which will affect its operational safety.

The first reason that made the news release incomplete is that it only stated that the hairline cracks were due to “localized impurities” during manufacturing process even though there are other aspect that may cause the hairline cracks. According to Hao (2016), different weather condition could cause defects to trains. For example, during heavy downpour, the rain water pressure exerted onto the train may cause hair line cracks. However, the news release does not address this aspect. In this manner, the news release could leave reader with only a partial understanding causing it to be incomplete.

The second reason that made the news release incomplete is that it only stated that the cause of cracks at the draughtscreen were due to errors during installation process. In my opinion, overcrowded train may cause the cracks on the draughtscreen too. The Kawasaki Heavy Industries & CSR Sifang (2016) (Fig 1.) stated that the capacity for seated and standing passengers are 296 and 1624 respectively. However, according to Tan (2016), train ridership rose up to 4.2% from 2014 to 2015. In addition, according to” LTA Strategic Planning,” (2016) (Fig 2.), at 6.15pm, there were an average of 179 000 of train ridership which shows clearly that the train are overloaded. When the train is overload, standing commuters’ tend to lean against the draughtscreens and the force exerted could eventually cause the draughtscreens to crack. According to Chew (2015), one of the draughtscreens on MRT train shattered (Fig 3.). In my opinion, it is possible for the same thing to happen again. Therefore, the news release would be complete if it had considered the train’s maximum capacity and laden weight per load that could be the cause of the cracks.

In conclusion, while the news release only discussed on what had been done in order to solve the defect problems, it should also consider several other aspects that may cause defects on the train such as different weather condition as well as the maximum capacity and laden weight per load. Although the entire "car body shell" of the trains were going to be replaced, if the other aspects are being neglected, new cracks on the draughtscreen would be formed. If this problem persists in a long term, it may break the draughtscreens. Thus, this would affect the operational safety of the trains'.
