From my understanding there will be 10 x 6 car trains and 19 x 3 car trains in the new fleet. There are no 4 or 5 car sets in this fleet as far as I am aware and the total of 117 carriages is 6 more then the combined XPT, Xplorer and Endeavour fleet. However it isn't the amount of carriages that matters it is the amount of trains that matters.
The 10 x 6 car trains barely covers the north coast and Melbourne XPT's and it certainly doesn't allow for any maintenance time especially if it has to travel up to Dubbo to do so.
There are currently 14 x 2 car endeavours and if you cover all of those with 3 car set trains then that leaves only 5 units for Canberra, Griffith, Broken Hill, Dubbo, Armidale and Moree trains. These numbers just don't stack up to being able to cover all the trains needed. Especially as they are setup as power car, trailer, power car and so 2 car operation is a no go.
The joker in the mix is the 7 x hunter rail cars. Are they enough to cover the hunter line completely?
As per wikiepedia there will be 10 x 6 car sets for long distance services. 9 x short regional and 10 x long regional.
Thankyou sims for correcting me. What has confused me is the designation of the regional intercity sets, which I interpreted to be the XPT replacements, but in fact they are the Endeavour replacements, being the 10 x 3 car sets, which are all Economy 2 + 2 seating without buffet facilities. The 9 x 3 car short regional sets and 10 x 6 car long regional sets are the Xplorer and XPT replacements respectively, with both classes having a mix of Economy 2 + 2 and Premium 2 + 1 seating as well as buffet facilities. The FAQ on the TfNSW website clarifies this.

The suggestion I made with regard to the allocation of fleet class in my previous post is still valid. The 10 regional "intercity" sets, replacing the Endeavours, will cover the extended intercity network beyond the wires providing through services to Bomaderry, Goulburn and Bathurst. Whether they will also continue on the Hunter Line is unknown at this stage.
The 9 short regional sets will most likely cover Canberra, Griffith, Dubbo, Broken Hill, Armidale and Moree. The Griffith and Broken Hill services will no doubt continue to alternate with the same sets, with a possible increase to 3 services a week, while the North West Armidale/Moree services will be operated with 2 x 3 car sets, splitting at Werris Creek as they currently operate.
The Dubbo service will depend upon whether an additional early morning departure from Dubbo is introduced. From my observation, the current daily XPT service generally consists of 4 passenger cars. A daily long regional 6 car set would seem to be excessive and a daily short regional 3 car set not enough compared with the current service. It would make more sense to have a twice daily service, morning and afternoon, using 3 car short regional sets for each service. That would roughly equate to a 50% increase in daily capacity.
The 10 long distance regional sets replacing the XPT services would service Melbourne, Brisbane and the NSW North Coast. Hopefully when Brisbane's Cross River Rail Link is completed, the Brisbane service will operate at more civilised hours with a possible extension of a North Coast service to provide a morning and evening service similar to Melbourne.
