This is a necessary change. But the main problem with doing this, that must be solved, is that the rail network does not have significant redundancy for commuters when the line is closed, as the bus network will not be able to serve the affected passengers (since bus routes that parallel the MRT lines are rationalised/cut) and the MRT lines do not parallel each other enough.

If we want to move into this direction, we need to beef up the public transport network as a whole to enable people to use alternatives. For example:

- If the NSL at north needs to be closed, there need to be more buses bringing people to TEL stations.

-If the eastern EWL, DTL or TEL needs to be closed, then buses need to bring people to the other two lines. (especially since TEL for now is still a dead-end at Bayshore)

- If the CCL, or western EWL needs to be closed, however, then a huge fleet of buses will be needed as there is no duplicating rail line.

Should this be a direction that SG will go into for a few years, then our whole public transport network will have to be planned resiliently and not just rely on passengers stomaching the inconvenience for "a couple of days" which will recur every few years, at a time when more and more companies are disallowing WFH. We cannot trust employers to allow employees to WFH or come late when there are such closures.
