In 1981, the Institution of Engineers suggested that a network of fast trains connecting Brisbane, Sydney, Canberra, Melbourne and Adelaide would be a worthy Bicentennial project. The electric XPT, now proposed to operate at 200km/h, was suggested as one option.

This is a proposed northern region schedule which was to have taken effect
from 14/2/90. It went as far as altering all the connecting road coach
services. It was entered into State Rail booking computers, but was
withdrawn before the new schedule was made public. Note that no up trains
stopped at Gosford plus NT17 and NT18 didn't stop at Strathfield, which is
most unusual.
