This model CAF costs about the same as any equivalent model from any other
manufacturer. Do you have any specific evidence that they are built more
"cheaply". They look to me as sound as any other. The only design glitch is
those bogie seats but that's not a quality issue. The shortage of doors is
down to TfNSW, not the manufacturer, a typical kneejerk response by an
operator to the loss of seating in a double-ended vehicle by sacrificing
functionality as a "solution" - which then comes around to bite them in the
bum when the operation turns out to be much busier than they anticipated.
