More of becoz MRT is less accessible to many of the commuters...
Hence if they hv Express or Premium at doorstep it would be first
choice for them.
And the medium-haul lines (eg. TSL) wouldnt actually do shit to
resolve the problem... Which is why I hate them so much
The TSL route is so weird as of now. Most stations like
Springleaf, Lentor, Caldecott, Mt. Peasant, Napier do not have much
housing around it, except for few condos. also I know many ppl live
at Lentor/Springleaf as it is much cheaper and they can afford car
then. Napier is full of rich ppl (using MRT unlikely).
Unless in next few years they launch new BTO projects around
these areas, the route is quite worthless today.
