What is the betting that by the time “they” reach Katoomba, a decision will be made to widen only as far as Mount Victoria and run coach services to Lithgow … and/or run a V-set shuttle between the two points.

This was all known when I was still on the job. RVX4 was sent over the mountains around 2009 or 2010 to do a laser profiling run. It identified the infringements to the narrow as well as the medium loading gauge. So all was known and the number of tight spots was not huge.
The main two tight spots were through the ZZ tunnels and the western end of Mt Vic yard at the single slip points.
Most engineers DO NOT GO into such ventures with their eyes closed and you can bet that the track alterations were in the original submission. Things like signal infringements would be dealt with by replacing an old type signal by an LED as part of upgrades and the single slip was to be part of a rearrangement of Mt Vic when it was to be removed and the track centres widened.
