Bro you got it wrong.
In fact it is the EXACT opposite.
109 SDs during peak will get packed to the door, even after
reaching Sengkang. And may I ask how many DDs are actually running
on 109? Proportionately the SDs would be more...
On the other hand, 89 has much more DDs than SDs during peak. In
fact, you wont even find any SDs during peak on some weekday
evenings on 89! As for the DDs most of the time the standees won't
even fill up half the lower deck. All seats taken though.
Now in terms of ROUTE. Which makes more sense: coming up,
stopping at stop and then resume as per normal or come up, stop,
wait for jam and traffic light, go down, and UP AGAIN?! I could NOT
think of a single route that would ultimately make 109 worth the
stop. All I think it does is destroy one of the main advantages of
109.
Hi mr SMB128B, sbs 89 has more double deckers because it is a
loop service and crowds are expected to be more. Sbs 109 is fixed
at 2 sides so uses single deck. With surge in crowds lately, double
deckers are used.
Sbs 109 still retains the main advantage even after it stops at
TPE stop. Why? The whole sector is still express except for this
stop. Other services also stop here but most have to stop at all
stops on their normal routes while sbs 109 is still express for
quite a distance. It still wins in terms of bus journey timing.
Cheers
