I think it depends on how SMRT AMDEP wants to allocate their
buses. So long got bus come and it also meets WAB criteria can
already.
If 805 and 883 are to be under WLDEP for sure will use full
fleet A22 already.
Anyway back to topic, I feel that LTA should have extended
services like 852, 853 or 857 to Sembawang, or maybe enhance 117
route and come out with a 117M. Instead of coming out this
relatively redundant 883 route.
