Is there any logical reason why the T80 runs that way on a weekend, rather than simply running a 10 minute headway service like it does during the week?
7 trips per hour operate from Parramatta, yet you still get 15 minute gaps between services, some of which are followed by a double header of two buses at once.
I know that the demand is much heavier at the northern end of the route, but for part of the day there are short trips from Bonnyrigg to Liverpool as well, to make it more confusing.
