at the end of day, SMRT will need to balance the cost of running extra train trips (i.e. shortening the waiting time) against their costs.
But i believe the crux of the problem is:
a) shortage of serviceable trains - not to say there is insufficient trains but because the trains need to be scheduled for routine maintenance and checks, putting more trains on the track means shorter servicing cycle, which will lead to breakdowns -(something not desirable). Not true. During peak hour they are running at 2-3 mins interval
b) the signalling system which severely limit the number of trains on the line at any one time and as well as the speed of each train. Not true again as indicated above.
Of course, none of the above are saving grace for SMRT nor LTA which has fucked up in estimating capacities. As well as the government who when they decided to open their doors to let in FTs, failed to recognise this point. Or they had indeed recognised this but chose to ignore this in view of swelling the population and thinking of:
- the general public will get used to it - like they always do
- fix this later and hopefully use the "benefits" of the FT swelling to convince us that such inconveniences are minor.
But as the GE and PE has shown, we are not taking it.
