Svc 167 is rather known for some unexplained things, especially
at the Upper Thomson Rd area, where svc 980 and 169 also plies as
well.
For example, when I was taking an 0405 back that hot afternoon, I
heard a handphone ringing non-stop, and of course, woke me up from
my sleep. Everyone took out their handphones but did not find
anyone calling.....The bus was half-full only and the ringing only
stopped a distance after the Upp Thomson Flyover....kinda funny
feeling though, and every pax in the bus was awake.
