The Chief Executives of LTA and SMRT trains responded to constant train delays by saying that re-signalling is a complex exercise. The signal testing has no choice but to continue for full days and especially under demanding conditions during peak period. They explain there are still mitigating measures like free bus services and in-station announcements to help commuters when there are disruptions.
"We are sparing no expense to improve our rail system’s reliability, including completing the replacement of the ageing signalling system, which turns 30 years old this year. We seek commuters’ understanding as we continue with the tests. We also thank readers for their suggestions and will study them."
