i wonder what happened to the proposed joo koon ter?
would be good to amend 79, 193, 252, 254, 255 and 257
to terminate there. probably 79 and 193 would do a loop system
like what it does in boon lay but this time round 79 will extend to
joo koon and loop inside 252's joo koon circle
segment while 193 will go from tuas to joo
koon, changing shift for 193 can be done at joo koon instead.
i presume there are less than 15 lots at the joo koon
ter which estimates 5 services (185, 252, 254, 255 and
257, 79 and 193 to loop there) being able
to PARK at joo koon
ter and so i presume 185 can probably extend to joo koon
ter as well. 252 should ply from joo koon - boon lay mrt (loop)
with out going into boon lay interchange.
boon lay is currently overcrowded, my idea would increase joo
koon's utilization and help ease boon lay's overcrowding.
boon lay needs change. change is good. 
I prefer Sv 193 to stay at its current route and shorten
182 and 192 to Joo Koon instead. 251 can be consider shortened to
Joo Koon also.
Also, for 254, it can consider starting from Tuas Terminal and
loop at Joo Koon MRT so that Joo Koon term will not be too
crowded while it can also utilise Tuas term.
Maybe Svcs 182, 185, 192, 251, 252, 255 and 257 can be
relocated to Joo Koon Term while 254 can be amended to loop at Joo
Koon from Tuas Term?
