This train operated from Cairns to Melbourne. Reading up a little more apparently they went through a bogie exchange at acacia ridge. How was this achieved?It did a number of trips south of the border, it was originally supposed to be fortnightly or something like that, but it didn't last as there was likely limited interest in the costly NSW NCL section and cost incurred of bogie change.
This GSPE train had the Global Financial Crisis (GFC) against it 10 years ago and then IF you rode on it, not to mention all that Shane has mentioned above, the bogies were absolutely terrible and did nothing for riding comfort. The old Inter-capital Daylight Express comes to mind...for those of us who can remember the days of 'the varnish' and that was a rough riding train as well...but I digress.Its a pity they didn't recognize the issues of the noisy and comfort earlier, bite the bullet and stop the service, get new bogies and start again, but the service was run into the ground so to speak.
The GSPE became so bad that the train slowed right down for meal service...and towards the end, on some sections of track, the train would not be travelling at all during the meal service, such was the shocking riding freight bogies under the cars. The fares were hideously expensive and rival the current I.P & Ghan expensive fares.
Finally after many years at Ipswich rail museum after the whole concept collapsed, the cars got shipped to NZ around 4 years ago if I recall.
