Assuming now SG is willing to go HK style.
And assuming now is 2017.
For svc 46/47,
A bit looping around CBP - 10 mins
ECP/MCE/AYE - 30 mins
A bit of looping at the respective heartlands - 10
mins.
Only 50 minutes! What's the benefit compared to EWL? Comfortable
ride, no transfer (MRT have transfer at Tanah Merah), less
stops!
What about svc 1?
A bit looping around CBP - 10 mins
ECP/KPE/PIE/BKE - 45 mins
A little loop at BPJ - 10 mins
65 minutes - as compared to a 34-stop journey on the DTL. Or
fastest scenario, 22 stops with 2 transfers. Both of which, with
reference to CCL rides, will most probably take no less than 75
minutes.
But again, more comfortable rides, no transfer, less stops! And
maybe a more direct routing!
And this is hub-and-spoke! You get "hub" bus routes and "spokes"
like svc 20!
All, let's be pragmatic. For the 4 bus services at changi
business park, 1 to tampines (east), 1 to northeast
(sengkang/Punggol), 1 to west and 1 to central/north. Not possible
3 to west side. Cheers.
