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)

Shorter hours on NSEWL: 4 shuttle bus services to ply affected stations

SINGAPORE: Four shuttle bus services will ply the routes along the MRT stations on the East-West Line (EWL) and North-South Line (NSL) that will have their operating hours shortened in December, SMRT said in a media release on Monday (Nov 27).
The buses, which will follow the same fare structure as trains, will ply the following four routes and will arrive at frequencies of between three to five minutes during peak hours, and five to 10 minutes during non-peak hours:
- Loop 1: Outram Park to Jurong East (both directions)
- Loop 2: Jurong East to Joo Koon (both directions)
- Loop 3: Joo Koon to Tuas Link (both directions)
- Loop 4: Jurong East to Choa Chu Kang (both directions)
The train operator earlier announced that 17 EWL stations and two NSL stations will be fully closed on Dec 10 and Dec 17.
In addition, from Dec 8 to Dec 31, the 17 EWL stations from Tiong Bahru to Tuas Link as well as Bukit Batok and Bukit Gombak stations on the NSL will close earlier on Fridays and Saturdays (at 11pm) and open later on Saturdays and Sundays (at 8am).
SMRT said its staff will be deployed at bus stops to assist and guide commuters from Dec 8 until Dec 31.

The two full-day closures and shortened operating hours were announced after a collision involving two trains at Joo Koon MRT station on Nov 15. The collision, which injured 38 people, was caused by a software glitch in the EWL signalling system.
SMRT said the shortened operating hours will more than double engineering and track access time from three hours to seven-and-a-half hours each night.
"With extended engineering hours from December 2017, the re-signalling works on the EWL will be completed significantly earlier by June 2018, instead of end-2018," it added.
SMRT Trains CEO Lee Ling Wee said the previous rounds of early closure or late opening of MRT services have seen the engineering teams "gain valuable time to work on tracks and trackside infrastructure". He added that parts of the train network that were renewed "have served commuters well".
"Our engineering teams will make full use of the additional time to perform train and signalling tests, and planned maintenance and renewal works on tracks, in MRT stations and in train depots," Mr Lee said.
More information on the closure and the shuttle buses available can be found on SMRT's website, social media pages as well as in stations and trains.
