each company has their different opinions and beliefs, just like
humans.
in this case, SMRT believes in their bendies.. SBST believes in
their DDs.
SMRT states that its bendies can carry more pax as there is a lot
of space for standees. however, i can say that this is not
maximised as pax simply refuse to move to the rear. SMRT even
criticises SBST for its DD as they're 'bulky' and 'hog up the
road'.
SBST however states that its DDs can carry even more pax. this is
due to having more seats on the upper deck. noting that no standees
are allowed on the upper deck, there is a standee area on the lower
deck(not available on LO3x tho). SBST then criticises SMRT's
bendies as potential road hazards and use up space at bus bays of
bus stops, making boarding for two or three buses at the same time
difficult.
all this can be found on an article in the straits times in
2005.
my choice? no favourites.
