I agree BBT to WL is far compared to KJ. 190,77 can also AM/KJ.
966,858 can go WL/AM. For 855 and 188 im nt sure need dual depot or
not. 926 shld just go to WL instead of KJ
852 can go KJ alright, but the main problem is that is would be
a hassle to go yishun from KJ, They have to maneuver around KJDEP
to Yishun which is really a waste of time to be honest.
Put it this way, do you want to spend your time going back to
depot fast (you'll go home fast) or you want to spend it on finding
your way back to the depot for a long and hard time?
I have no preferences but which is better? You go back to
depot the shortest time (you'll go home early) or you'll take a
longer time travelling around where to find the depot (which will
take a longer time)?
852 can be KJ/AM
