I believe 170e may be a Singapore-side only arrangement between
Queen St and Woodlands CIQ, where passengers can transfer to a
normal 170 to Larkin or Pasar Bakti after JB CIQ, since it's the
fastest option anyway.
And I believe 170e will be out only after the fleet renewal, when
rectangular destos will be introduced.
Yea, 170e is most likely SG arrangement only. They'll have to
get approval from authorities from Malaysia. Also, the route
between JB CIQ and Larkin/Pasir Bakti is a short trip with 160/170,
so there isn't much of a point introducing a new service, going
through authority hassle for a route duplicating 170, except
faster.
i think the MKIIIs going of at 2010 est. (1 more year). So making
the plastic destos that MKIIIs using right now not really worth it.
Means have to wait for 1 more year before 170e is plying.
Most likely they'll use MKIV DM or Striders first. Don't think
they'll use the newer DM3500s.
