No need for fanciful ideas I guess. Just increase frequency and
the speed of the ATO. It is possible to do so as I've taken trains
before on NSL and EWL whereby the train is late and hence has to
speed up.
Also increase the frequency to exactly 2 minutes (currently it
is on average 2.5 - 4 minutes for peak hours). It is noteworthy
that the NEL system can cater to up to 90 second intervals between
two trains.
The thing is SMRT adjusted not just the timings of the trains,
but also the signals. You can stand at a station waiting for a
train which comes only 8 mins later and the signal will still be
red until 1 minute before the train arrives at the station, when
logically, it would be safe after 1 or 2 mins, as seen from peak
hour frequencies.
