Few neasures here may help to mitigate and minimise MRT disruptions and safety :-
(1) Failsafe, failsoft mechanism - eg, if signaling software fail, hardware eg. IoT take over - if not human backup must be able to manual override and take over if signaling software fail.
(2) Redundant lines - to be able to shut down the whole line for maintenance, repair and fail over to redundant line eg, the up and coming redundant thomson line from Changi, Ang Mo Kio to Jurong (NUS, NTU, SP, NP, UniSim, One-North, Science Park) ---- will alleviate and provide redundant to the Green line (East-West line) and Red line (Ang Mo Kio line to Jurong East).
(3) Improve work culture and morale of staff - demoralise staff will not put in extra effort to make the system work or improve the system.
(4) Parallel bus system (that run along the MRT station) - able to beef up during MRT disruption
(5) Proactive, predictive, reactive maintenance - to upgrade and improve the parts that are 20 to 30 years old.
(6) Realtime information dispensement to inform public - that eg. "A" line is unavailable for servicing and move over to "B" line. (This is the same as London tube - where one line is taken down for servicing, a parallel line is activated to serve public. And if both lines are down, bus system that ply the MRT stations are activated). --- 3 redundant public transport system in place. If to be more kiasu, activate PMD, hire-bicycle also put in place - for those who are adventurous to rely on during disruptions.
Make this a standard modus operandi that public will take it as natural course.
---- All mechanical things, or software, or hardware, or system --- will fail some point in time - and need maintenance, servicing, repair.
----- The key is there will be a failsafe alternative, failsoft mechanism to mitigate, redundant system to seamlessly or close to seamless take over of main line if fail.
eg. car will fail on the road and need maintenance.
air con will fail and need maintenance.
computer system will fail, and need redundant system to take over.
etc etc.
Make public understand this.

Since the parallel MRT thomson line that run parallel to East-West Line and North South line are still work in progress and not available now -----
"May have to consider using Bus services to run to all MRT stations ---- for eg. service provided during peak hours --- eg. go office hours and after office hours --- to backup MRT lines).
If MRT lines disrupted --- parallel bus service can be beef up =------ until the new parallel MRT line is available."

To save cost, this parallel bus service vthat run along the MRT stations will not run during off-peak hours.

Best still come up with a transit guide, information display system etc- to illustrate the redundant systems :- eg.
(1) Line A - normal (or disrupted - go to Line B, C and D eg.)
(2) Line B - normal (or disrupted)
(3) Bus service C - normal (or disrupted)
(4) hire PMD, Hire bike D - normal (or disrupted)

ya, u r right ! I was once a soldier,i did my ns and reservist. I m not frightened by a single disruption,i m frightened by multi-disruptions as i was nt frightened by a single bullet but frightened by multiple bullets such as machine-gun. But now,i m a paying commuter & i depend on a good reliable transport.

You have to imagine yourself living in your house - but your electrical system, your water pipes, and many of your gadget is reaching its shelf life - and need to replace or upgrade.
And you will need to continue to live in the house, use your gadgets, use electricity, use water ---- while your contractors replace your water pipe, change your electrical system, or service your gadgets such as your air-con, your fan, your computer etc.
In the midst of this, won't you experience multiple disruptions --- or are you expecting no disruptions at all?

Or would you fire your electrical contractor if he cause your computer to trip while he replace the electrical circuit?
Or would you fire your water pipe contractor - when you bathe and the water supply is cut off?
Soon you will find no contractors working for you - or no contractors want to take up your project --- and your house will be in deteriorating shamble state.

Now the MRT are reaching 20 years and 30 years shelf life - alot of parts, signaling sytem need to be replace, upgrade.
New MRT lines with new signaling system and parts are coming in - and need to integrate with the old system. Signal interference will bound to occur.
Like the analogy of your house to be upgraded and repair - multiple disruptions will bound to occur.
Unless you are willing to live in the park while your contractors revamp the whole house or if commuters are not taking MRT for 1 whole year while the MRT is revamp ---- then upon completion disruptions will be minimal.
Are you willing to do this or are commuters are willing to commute without MRT for 1 year?
