[Armchair] Should V/Line commuter lines be electrified?

Why exactly would dual-voltage be required ?
Just change the entire Williamstown, Werribee, Sydenham, RRL tracks to 25kv. Sure you couldn't continue past platform 15/16/? at SouthernCross station, but that's not a huge issue.

Main problem is newport railway workshops being in a 25kv area, a bit of a good and bad news thing.

Then since we're in cushy armchairs, we might as well convert the whole metropolitan network.

Dual-voltage rollingstock is required because it is otherwise impractical to get regional EMUs or locos to the Newport workshops and elsewhere on the suburban network. Leave the Williamstown, Werribee and Sydenham lines alone - just electrify the RRL tracks and the RFR line past West Werribee at 25kV AC. Don't do any more than necessary. As I said earlier, dual-voltage working is trivial nowadays if you use the right rollingstock.

Converting the rest of the network is uneconomical and unnecessary. 1500V DC works fine for metro networks - the higher service frequencies mostly make up for the need to have extra substations along the line. If you start talking about that then you may as well go the whole hog and convert the lines to standard gauge at the same time.

If you wanted to fully recline into armchair mode, then you should build Melbourne Metro at 25kV AC and convert the Cranbourne, Pakenham, Sunbury and Melton lines to 25kV AC. Run that group of lines as a completely separate part of the network as PTV intends to in the future.

We should have converted to standard gauge when we converted to auto couplers.

Having direct links to those in transport planning there have been at least 5 studies that have looked at electrification of the Geelong Corridor in particular and the numbers have never really stacked up. This is especially so given the ongoing orders for VLocity railcar sets and the very latest order which is well into building phase.  At any given time if you look at the history of rail electrification schemes they have pretty much coincided with major upgrades to networks or to handle substantial new business.  The next generation of development in Victoria is more like to focus on a high capacity diesel multiple unit option for the Geelong Line and based on growth forecasts double tracking and extension of electrification to Melton.  Those two projects not only handle future growth but do away with all the H sets and transfer all the VLocity sets to manage growth beyond Melton, plus Bendigo, Traralgon and Seymour.

Electrification to Geelong would require new train sets plus the overhead.  It might have tacked up at the time of planning RFR but operationally and materially it doesn't now. It would be purely for political purposes.

And for the future building a tranche of non powered intermediate VLocity cars to create 4 car sets is another option. The design has been done. Tests have been conducted on what the impact on performance of a 4 car set would be be with only 3 powered cars and it's absolutely negligible. There are many services not just to Geelong that would be well suited to a 296 seat 4-car consist.
