I'm not sure of the number of buses going to Adelaide either, but I'm sure that 20 buses
a day does not equal one bus an hour. It probably means 10 buses leaving at the same
time, twice a day; or at best 7 buses leaving at the same time three times a day. I
remember a bus trip I took from Melbourne to Sydney some years ago (the train was booked
out), and distinctly remember a refreshment stop at Albury, we arrived and there was
one bus there also stopped for refreshments. Within 10 minutes I counted 13 buses - all
going to Sydney. Those 13 buses did not represent a 2 hourly frequency of buses, but the
equivalent of probably one 10 ten carriage train travelling on the Hume rather than rail
tracks. Food for thought .
