Some 72B buses have empty upper deck btw, not all are
full.
IMO, 902 should be kept as SD fleet, or bendy. The freq prob
need some adjustments. Anyway, there would be some students
skipping the packed bus. So frequency is the factor, not
capacity.
maybe u r talking about the last few 72B DD trips at 10am to
1015am??
any other trips of 72B buses usually will depart only when there
is enough paxes..
the timekeeper there will pull the buses over to the boarding
berth when the paxes are building up.. they wont suka suka ask the
72B buses to depart when there is few paxes only....so no
possibility of empty upper deck from 7am to 945am....
