Electrification doesn't have to mean metro. If Adelaide can put panto's onto a vlocity then why can't vline. Vline should convert all non metro lines to the north, west and south west to SG and electrify to Geelong, Ballarat, Bendigo and Seymour.
Can I ask what would the benefit be of running a diesel Vlocity vs an electric one?
Do the electric ones pull the chicks?
For the sake of entertaining the argument, Adelaide didn't put the Pantos on the Vlocities. Bombardier did. While the A-City 4000s are based on the Vlocity "shell", I honestly don't know how similar they would be in reality. I know the fit out in Adelaide's case is totally different to the Vic Vlos. As to the wheels/bogies, motors, running gear, etc. Well I don't know how similar it would be to the Vlos, nor how similar it would be to other electric metro rolling stock in Melbourne.
And again, what would the benefit be?
(Also bear in mind that Adelaide's electrification plans have pretty much hit the skids)
Just on a side note, the fact that you are suggesting electrification to Ballarat, Bendigo, and Seymour is laughable. We had electrification to Latrobe Valley for the coal trains. And despite still being the state hub of electricity supply, they ripped them all up because of maintenance cost and lack of need.
