Using a new measurement method called the “mean kilometre between failure”, the Managing Director of SMRT Lee Ling Wee claimed that train reliability has improved since 2013. Despite increasing frequency and duration of train breakdowns, the SMRT MD wrote in a blog post that he expects rail reliability to improve due to the “trend” in his chart (above).
According to the former army general, Lee Ling Wee wrote that 33% of the delays occurred due to signaling fault. The situation “will improve” because SMRT is upgrading the signaling system to a Communications-based Train Control system which is supposed to have more redundancies as compared to the older system. However, the new system can only be fully implemented in all lines by end-2018.
The SMRT MD also claimed that they are catching up with their counterparts in Hong Kong and Taipei and that SMRT is getting better:
“Nonetheless, with a laser-sharp focus and a never-give-up determination to catch up with our counterparts in Hong Kong and Taipei, we believe there is only one direction for NSEWL rail reliability service to go in the coming years: Up.”
Interestingly, the SMRT MD also posted a “ticketing machine reliability” chart boasting a 99.96% reliability rate in an attempt to obfuscate his readers with rail reliability.
