SINGAPORE — Serious MRT disruptions, each lasting over 30 minutes, more than doubled in 2022 from 2021 even as the frequency of total delays dipped. According to rail reliability statistics just released by the Land Transport Authority (LTA), the mean kilometres before failure — an engineering measure of reliability — rose from 1.994 million train-km in 2021 to 2.09 million train-km in 2022. That means there was one disruption of more than five minutes for every 2.09 million km clocked by Singapore's MRT trains during the year, making the system one of the more dependable in the world. The best-performing MRT line was the newish Downtown Line, operated by SBS Transit, while the worst-performing one was the North-South Line, operated by SMRT.
