I don't think they are targeting people from AMK to Shenton Way,
they have premium. More like individual sections like AMK-TPY or
Bishan/Braddell (where there is a very silm chance of getting into
the train)-Novena/Newton/Orchard. They are using price (esp with
season pass) of the good/service to attract people.
