5 does not go to the west as BM is within central area, so west
side effectively only has 7 as the sole single-digit service. If 1
were ever to be introduced, it should preferably serve the east as
it would complete the 1-9 set serving the east area. If anyone
notice, the first 39 services in consecutive numerical order (2-40)
have a terminus in the east side with the exception of 11, though
some argue Geylang can be considered to be part of east side
because of its geographical proximity to Bedok.
IMO the unused number routes between 1 to 200 can preferably be
used for future services in these areas:
1/44/68: Anywhere in the east
71: YCK/AMK
104/108/110/114: Serangoon/Hougang
126: Bukit Merah/St. Michaels
137: AMK/Sims Place
144/146/148/149: Toa Payoh/Bidadari/Lor 1 Geylang
152/164: Sengkang/Punggol
So it's better Clementi have a new svc 1 in future.Who would
have thought 41 & 49 will be at West side when
40,42,43,45,46,47,48 serve Eastern areas?Who would have thought 127
& 129 will originate from Tampines?With LTA planning,It's not
suprised.Im not suprised if SMRT svc start from Northeast using the
usual SBST svc number also.
