It was a devastating memory about Singapore's Mass Rapid Transit failure during weekends for maintenance! In that incident the NSL, EWL were closed for inspection by the LTA, following two major memories that I had two train disruptions in a month that affected 200,000 commuters. (Memory collected at the Sengkang Public Library during the "The Singapore Story: My Heart, My Hope, My Home" campaign from 6 Sep to 31 Dec 2012)
