Train delay galore, Episode 03

I can't believe it. SMRT broke down again this morning, making it the third train delay in four days. What is wrong with them?

I heard the news from 938 Live, and the delay seemed like a contagious illness which affected Marina Bay to Newton MRT stations first. It then started spreading to the other stations followed by several 'false recoveries'. Here's the condition of the 'patient', from SMRT website (yes, they finally bothered to update it in a more timely manner):

755am: No train services between Marina Bay and Newton

818am: No train services between Marina Bay and Toa Payoh (condition worsened)

825am: Northbound train services from Raffles Place to Jurong East have been restored, but still no northbound train from Marina Bay to Raffles Place (moderate recovery)

850am: Northbound train services from Raffles Place to Ang Mo Kio are down again, and southbound train services from Ang Mo Kio to Marina Bay are now unavailable (condition deteriorated sharply)

900am: Northbound train services from Raffles Place to Jurong East are available again (moderate recovery)
1000am: Southbound train services from Ang Mo Kio to Toa Payoh have been restored
1055am: Southbound train services from Toa Payoh to Newton have been restored
118pm: Southbound train services from Toa Payoh to Raffles Place have been restored
148pm: All services have been fully restored, but expect delays. (fully recovered but relapses are expected)

I hope there isn't an episode 04 to this.
