    Five major MRT service disruptions in Q1 of 2015

    FIVE major MRT service disruptions occurred in the first quarter of this year, close to half the total number of incidents last year, The Straits Times has learnt.

    According to figures on the Land Transport Authority (LTA) website, there were five service delays lasting more than 30 minutes between January and March.

    For the whole of last year, there were 12 such disruptions, and in 2013 and 2012, just eight for each year.

    The incidents this year include a 4hr 38min breakdown on the North-South Line on Feb 23, between Yew Tee and Kranji stations. This was due to a damaged power-collecting device on the train that affected the third rail, which supplies power to trains.

    When the number of major service delays in the first quarter of this year are averaged out over 100,000km of train distance travelled, the incident rate is 0.07.

    This is up from 0.04 last year, and 0.03 in 2012 and 2013. It is also higher than 0.05 in 2011, which saw two major breakdowns on the North-South Line in December of that year.

    But the overall number of minor service delays - which are defined as being more than five minutes - has fallen across the MRT network. The incident rate in the first quarter of this year was 0.79, down from 1.17 last year.

    Four major service delays occurred in the LRT network in the first quarter, with all the incidents occurring on the Bukit Panjang LRT system. For the whole of last year, just five such service delays took place across the LRT network.
