Maintenance of MRT tracks

Why is it necessary for SMRT to close some stations for track maintenance during the weekends? Is this a regular feature in some other countries?

We are dealing with routine track maintenance. How long does it take to "maintain" the track? What is involved?

We are not talking about faults in trains. These faults can be attended in the maintenance depot. We are not talking about signal issues.

For track maintenance, I suspect that there are some parts of the tracks that need to be replaced. These parts are still working but does give problem to some trains some of the time.

The first step is to identify the sections of the tracks that give problems. This can be done by looking at the data that is collected when the trains pass through. I shall describe it as "smart maintenance", i.e. using data to locate faults. Is this being done?

If all the tracks that need to be "maintained" are identified, how long does it take to repair or replace these sections? I don't think it will take hours. It should be possible to carry out the work during the five hours in the early mornings, when the system is shut down.

For the maintenance work to be done effectively, we need property trained maintenance technicians who are given the right tools and are properly supervised by competent supervisors. Is this happening?

In some countries, the quality of the workforce is poor. The workers are slack. The supervisors are not competent and not on the site supervising the work. Are we facing the same syndromes in Singapore?

I repeat. I suspect that there is no need to close the tracks for regular maintenance. The work can be done using smart data analysis, competent technicians and supervisors.

This is another sign of the bad state of affairs in Singapore under the current government.
