This was a simpler time, when Sinkieland was not an overpopulated shithole as it is now.
I think this wasn't the first version of the MRT network... at the first launch the train terminated at W8 Clementi, Jurong East and the stations immediately west and north of it were not yet completed.
Wait till the Jurong Region Line and Cross Island Line join in the clusterfuck of it all.
