Yes, a new service to Sengkang West would be great, would be
even better if make it follow the 27 route to Sengkang Int first,
then continue to Sengkang West and end at Punggol Int.
Route would be like this: Tampines Int>follow svc 3 route to
Tampines Stn/Int stop>folllow 27 route till Sengkang Int>turn
into Sengkang Int>proceed to Sengkang West>proceed to Punggol
Int. Maybe can call this service 68. DDs should be deployed for
this service for a more
comfortable ride on the expressway as it would be high
demand.
There will be no need for additional peak hour buses for service
27 and the frequency can be lowered to reduce bus bunching.
For me i think the service should go like this,
Tampines>TPE>Sengkang(Compassvale/Anchorvale/Fernvale)>CTE>Toa
Payoh
But then TPY Int looks full.
Anyways, Service 20 will help to reduce the loading on Service 38.
To me, the "express sector" will be better if it goes via Somapah
Road so that it will ply outside Expo Station/Changi City Point,
since Expo Drive is closed for DTL construction.
