Surprised they touched 18 instead of 4/19/37/81; not only is the
route longer but there's significant duplication to 28. Perhaps
modifying 38 may have been a better move?
118's amendment seems bad, there's considerable demand along CS
Ave 2 (for both 47 and 118).
Both 137 and 298 are interesting. 20 is well expected.
No changes to 46 with the modifications of 18 & 293, can
keep and probably extend to Pasir Ris in the future.
38 connects Simei residents (esp. those in inner roads) to
Tampines East MRT. If 38 is touched, travel time would be
significantly longer.
118's skipped bus stop is within walking distance to Changi
South Ave 1 iirc. If they're really lazy they can also take 47 to
Ave 1 and transfer to 118.
18's duplication to 28 is not a big concern IMO, as the routes
between Tampines MRT and N3 are quite different (in fact, most of
28's loading from Tampines MRT are towards Ave 9 / St 45 only).
