If my hypothesis is correct (refer to previous post), here are
more supplementary services that LTA MIGHT introduce:
(This list is only based on current SWTs. Some of them may not
have a suitable bus terminal or may duplicate other existing
services. I'm not saying I'm supportive of all of them.)
3M: Pasir Ris Int - Pasir Ris Dr 1 (Loop)
13M: Yio Chu Kang Int - Bishan MRT (Loop)
27M: Hougang Ctrl Int - Tampines MRT (Loop)

36M: Siglap Rd - Tomlinson Rd (Loop)
55M: Bishan - Ang Mo Kio Ave 10 (Loop)
60M: Eunos Int - Bedok Reservoir Rd (Loop)
70M: Yio Chu Kang Int - Serangoon MRT (Loop)
100M: Serangoon Int - Aljunied MRT (Loop)

138M: Ang Mo Kio Int - Ang Mo Kio Ave 5 (Loop)
145M: Henderson Rd - Redhill MRT (Loop)
154M: Taman Jurong Ter - Lakeside MRT (Loop)
158M: Aljunied MRT - Rhu Cross (Loop)
169M: Woodlands Reg Int - Yishun MRT (Loop)
178M: Woodlands Reg Int - Kranji MRT (Loop)
183M: Jurong East Temp Int - Toh Tuck Ave (Loop)
189M: Bukit Batok Int - Bt Batok St 23 (Loop)
198M: Boon Lay Int - Jurong East Ave 1 (Loop)
857M: Yishun Temp Int - Yio Chu Kang Rd (Loop)
962M: Sembawang Dr - Admiralty St (Loop)
965M: Woodlands Reg Int - Yishun MRT (Loop)
969M: Tampines Int - Yishun MRT (Loop)
975M: Bukit Panjang - Lor Rusuk (Loop)
Most of the ones that were needed have already been launched.
The ones that could make sense in future:
36M, 100M, 106M, 158M - all others strictly not required on full
day basis.
Note some like 189A, 183B are required only during peak hours to
cater to industrial crowds.
