I dunno does anyone noticed tis during off peak hrs at
Kranji.
There's tis group of 3x CW1 buses tat would arrive very close to
each other. Sometimes it would end up brunching to and fro KRJ
& JB CIQ.
At 1st I thought CW1's freq is super good even though running
close to kosong, only to realise it's something to do w/ layover.
CW1 does not even have a proper layover.
KRT, Larkin dun call. Kranji no one bothers to make 1 round to
form up for layover. JB CIQ has only 1 bay for CW1, 1 bay for
CW2... where gotch enough? 
Goes to show their efficiency level w/ CW3's Cafe terminal
mess.
