Dear Minister
Dear Hock Yong, Bok Ngam

I cc PM, two DPM (Finance and Home Affair Ministers) engineering, money and rescue effort must be in placed.

I cc Vivian for good effort, seemingly there is no flood reported despite intense rain in recent one week as alerted twenty one days before this bout of days long rains. (it is best time to work with weather department and LTA, Traffic Police, Transport operators to see where we did right, where are next likely improvement, bottleneck)

I am most ready to assist, do not invest in another team of same domain world experts who are yet to master how to accelerate river flow on a small island.
Let this be an opportunities we learn and progress together, let Singapore be an ever learning, progressing nation.



Structure

.........




Design

Recently I noticed there are green light on the station head, aligned with where the train heading stopped.
There is a green light when cleared to move.
However, the control panel, the cable harness are of casual design, they can be penetrated easily.
On one occasion, the driver has to stop, alight the train, move out to close the control panel box(which was ajar), before green light is on, he can move on.



Management

I noticed on more than 5 occasion, the train station is different from what is announced, or displayed on the LED panel in the train.
Car 1068 heading from Sembaway to Jurong East at 1607hours today, 2011 12 03
Display and Read Yew Tee as next station, immediately after leaving Yew Tee.
This error repeated till Jurong East Station, one station late.

This is dangerous.
One of these misinformation may cause the disruption of train services, worse collision of trains, worst case scenario – piling up of many trains.



Please advise action taking….

Network problem on Circle Line has no impact on safety: SMRT

By CARINE LEE

SMRT on Thursday assured commuters that the communication network problem on its Circle Line has no impact on its system safety.
The communication network problem caused a service disruption on the Circle Line between Marymount and one-north MRT stations at Wednesday morning peak hour. The problem has yet to be resolved.
To commence service and maintain the scheduled train timetable on Thursday, SMRT deployed staff to man all Circle Line trains. SMRT said it will continue to do so until the fault is resolved.

    MRT breakdown: Dislodged rail claws found by SMRT and LTA
    By Maria Almenoar
    Dec 18, 2011

    After a night of combing the MRT system, engineers from SMRT and the Land Transport Authority have found 21 damaged third rail claws which secure the rail providing power to the train.

    When these claws are dislodged, the rails are no longer aligned with collector shoes on trains and as such power to trains is disrupted.

    The claws have since been secured in place with additional steel brackets and cable ties.

    Thirteen trains have also been damaged and will be taken out of the system to replace their collector shoes.

    LTA has also found preliminary evidence that there may be a relation between the dislodged claws and areas where floating slab are built.

  2. These floating slabs are built in areas of the train network where there is a high density of buildings and there is a need to minimise vibrations.
