OK - Error of fact. Sefton Park Junctions is 20.657 kms from Sydney.
Cabramatta is 31.991 kms VIA GRANVILLE!!! This is where you are
getting your 11.334 kms from, but it is wrong. Cabramatta via Sefton
is only 28.450 kms from Sydney, which means that the distance between
Sefton Park Jctn and Cabramatta is only 7.793 kms. Therefore, the
average speed for 5 minutes over 7.793 kms is only 94 km/h.

> speed of 136km/h! Were such speeds really allowed in the suburban area?
It does 160 km/h at Mt Druitt.
> Most locomotive hauled train ran the same section in 7 mins (97km/h).
