You might as well extend it to Serangoon to serve Serangoon -
Sengkang serving 321 rt. So that it will be a trunk service.
Making it a day service would have some consquences, some
passengers would complain that the service only serves 0515-1900
(Wkday) 0515-1400 (Sat) and no op on Sun/PHs. It cannot use the
model of sv 6 as it is serving a new town.
