I am not sure if I can say this..this is what I observed and
suspected so I put in this thread first..
SMB209B-SMB215H seem to be deployed on 172
on its respective off days..have observed this for a few months and
for this week, this is what I observed:
Sun: 209 on 172
Mon: 210 on 172, 209 not on off but on 172
Tues: 212 not on off but on 172
Wed: 212 on 172
Thu: 213 on 172
Exception of Tues as 211 was missing since its last appearance
on 307 on Monday. Not sure if other users spotted it..so I am not
sure if I can conclude these buses as 307/172, or its just that
172/307 buses are interchangeable but none of the 172 buses behave
like this except maybe 103, 105 and 125..but not as frequent leh…or
just pure coincidence that 172 always have missing buses that
require the particular 307 bus that is on off?
What u guys think?
