When is it taking effect? for yishun side i guess is 852 going
from WL to KJ and 859 going to AM from WL then for Woodlands, is
178 and 187 giving some duties to KJ, Sembawang is 882 going WL.
Bukit Panjang is 180, 700 and 970 going WL.
859 is not affected because 859 is full WL. 882 is the sole
fully controlled AM svc in SE to be transferred to WL
