I said this before.. nvm i say again..
This system is used for St mikes services as they call along jln
bahagia twice - once when going out of St mikes area, and once
going towards the terminal.
IN means going INTO St Mikes estate
OUT means going OUT OF st mikes estate (going towards Balestier
Rd)
This is to differentiate the diff directions the services are going
so that pax will not be confused with it. As they live there for vv
long, they've grown accusstomed to the system.
