Maybe I should create a new thread to discuss all about weekend
bus deployments, be it SBST or SMRT buses.
From what I notice nowdays...
SBST
Services 62, 80, 87 and 89 have SD replacing DDs on weekends and
public holidays.
SMRT
Services 169, 180, 184 and 856 have rigids replacing bendies on
sundays and public holidays.
Whereas services 857 and 980 have perm weekend bendies replacing
some rigids.
These days, 180 seems to be unaffected on saturdays, sundays and
public holidays, especially after JP2 opened. Bendies are still
deployed most of the time, with the exception of 1 or 2. Guess the
demand is still high on weekends with many taking the service to
Jurong Point.
176, 190 and 700/700A also have irregular fleet deployments on
Saturdays, Sundays and Public Holidays.
