3. It would not be advisable to extend 56 to Ang Mo Kio. There
are already a few links from Toa Payoh MRT and Ang Mo Kio MRT eg.
73, 88, 159 of which 88 is fairly direct. 56 covers the entire
stretch of Bishan St 11 and 13 and would have to make a big
round to get back to Bishan Rd ie. via Bishan St 14. (Bishan Rd
(Raffles Institution!), Bishan St 11, Bishan St 13, Bishan St 14
and Bishan Rd again) Due to this, the demand from Toa Payoh MRT to
Ang Mo Kio MRT would not be great. I myself would prefer to take
88. Furthermore, there's 133 from Ang Mo Kio to Marina Centre.
4. 107 and 153 serve Serangoon MRT along Upp Serangoon Rd.
There isn't a need to reroute them.
5. 105 and "other buses" call at Serangoon MRT since they
terminate at Serangoon Int.
7. I dun get what you mean. Don't 105 and 132 call at Scotts
Rd?
8. Err.. seems to duplicate 174.. though it is a good
idea. :D
9. There isn't really a need.. the buses get fairly empty after
Toa Payoh and 56's main sector of demand is from Toa Payoh - Marina
Centre.
OK.
5. Serangoon MRT station's bus stop at B03/B04 Serangoon
Central. Currently 105 skips that stop and runs into the int.
7. Use Thomson Rd -> Scotts Rd
