do u all know, 156 isnt really popular between MacRitchie to
Clementi area, because it makes one big round at Whitley...
also, at night from Clementi, the bus is near empty. at 6th ave, at
9pm last time, the bus only 3 people..
156 load wasnt very good all along, even from Serangoon. since
there was 53 to Bishan also. now, popular between bishan and
sengkang, but frequency remained at 15mins
