Haha, just joking at my previous post.
Anyway, SMRT could just extend the platforms at all stations. A
curve at the end is alright. After all, most underground station
boxes are longer than the train itself. Narrow platforms at the end
shouldn't pose much trouble. With this, 2 new cars per train should
be sufficient.
Of course, frequency too. Time to upgrade the systems. Let's
have a 1-minute frequency just like Hong Kong.
Extending the train without extending the platforms is a no-no.
It will be extremely difficult to squeeze through 25 meters just to
get to the nearest door.
Wait a minute, now I recall I read some where that they have
been asked to increase frequency but their reply was not
possible.
