I already have a question for LTA:
Why custom-made a three-door bus, when there are already
three-door buses in the market?
(Custom-made bus costs more money. Those already in the market
is cheaper because the production cost is spread over more buses;
economies of scale.)
Especially the single-decker bus. As far as I know, bus
manufacturer "MAN" offers the third door option for single-decker
bus.
Personally, I feel that the second staircase and third door
design of the MAN double-decker concept bus is messy. They should
have chosen the other design, where the second staircase and third
door are at the back of the bus.
Because its political...STK is under Temasxx even though the bus
cost over $600k and ADL $490k
