Mass Commuting Disruption Caused by MRT Off-Service, are both a "design" and an "outcome".
When news broke that rail network to be further expanded, I am not that excited.
In fact I have
reservation that, in the near future this extra rail network may be an added burden
to the Transport Ministry or LTA.
It is a bit abnormal to
see that since GE2011; The Transport Ministry is seeing baton changing hand
that frequently, from Mr. Raymond Lim to Mr. Liu Tuck Yew. What exactly worries me is
that, whenever the affected Minister resigns from the Transport Ministry; each
time, this Minister left the said Ministry; to a certain extent, I believe, somehow,
it is related to MRT earth-shaking breakdown by Singaporean’s yardstick.
To recall, when train
breakdown and the un-expected surge in commuters traffic months prior to
GE2011; Mr. Raymond Lim, left the Ministry. And just a couple of months before
GE2015 (i.e. 7/7/2015 breakdown); Mr. Liu, decided to leave the Ministry too and do not wish to context for the coming GE 2015.
So the follow-up question for after GE2015 will be; by adding more
rail networks till 2030s, can the rail operators assure the Transport Ministry
that, there will be no similar proportion of train breakdown, like what have
had happened on the evening rush hour of 7/7/2015?
In my view, if the
Ministry have done all the required processes audit with due diligence, to the current
rail network; and if the failure or train breakdown were to happen again within the
next 5 years (2015 to 2020); and whereby its causes are actually related to the natural law of
impermanence; and are systemic in nature; then, in my view, this certainly does not
warrant the future Transport Minister to resign.
To support my view, I would wish to borrow a know-how from statistic; on the subject of Statistically Process/Quality
Control.
My understanding is that, what the rail network is been subjected to what is known as defective part per million issue (dppm). Assuming the rail network circuitry and processes are already in excellent tip-top conditions; with a process capability of 6-sigma; statistically speaking, there still be 3.4 count of defects or failure that can cause a major train breakdown.

To explain further, our entire rail network is actually fueled to
operate by electricity.
The electric current
has to be connected in a circuitry manner. However, when there is a small electric disturbance or intermittent in one
remote branched-tail end of the circuit; it is capable to affect (in a negative
sense of words), the entire electric current supply to operate the trains;
leading to the rail network been shut down promptly.
I suspect it is an in-built
or been designed electrical system, way back in 1980s.
Whereby, with just a small electrical fault here or there, the effect is always a mass disruption to the commuters.

With a 3.4 dppm count; by all international quality acceptance standards; this is certainly a negligible
defects rate.
However, the way our current rail network been wired and sewn up; even with just 1 count of electric fault, the rail network will stop operating, and its inconvenience caused is always detrimental to all affected parties.

A lot of caustic
remarks will be forthcoming by the public at large; and the Minister or the
Transport Ministry and the rail operator will usually suffered the most of this (negative remarks or scolding), at the other end.
Lastly, the bottom line is
whether can the public commuters accept this extremely low defective rate, and
be grateful to the Transport Ministry and the rail operators that, for every 1
million trip done; there are 999,997 successful train trips to ferry you from MRT station
to your workplace or home; or continue as you wish to increase the caustic intensity of your words to the Ministry and to the rail operator, when
there is just 1 train breakdown.
You decide
