Not sure I understand this. The choice would be between overhauling the DC motor, or replacing it with an AC motor but also replacing the traction package.

The effort is fairly similar, that's how the SWT ones are justified.

That may be so for the motor, but what about the traction electronics?
Not enormously significant, once you're at the stage of remotoring a whole train.

Same news as always, replacement is not yet confirmed, but highly probable in the next franchise.

They’re staying for another 15 years at least

Can the Southern 455s be retractioned like the SWR ones?

Yes but why would they need to? It would be much easier to act quickly and just take the SWR fleet instead as they go offlease.
From earlier discussions, retractioning was only justified on the SWT trains by them having 10 years left in service, and reducing maintenance activities at Wimbledon to fit the 707s in. Neither of those justifications would necessarily be relevant to SN’s 455s.

London Overground should be taking over all the franchises' metro services and then the fleets on SWR, Sthn and SE could be replaced with a homogeneous fleet.

Then SWR will already have an LO compatible Aventra fleet, so only SN and SE to sort out...

No their lease expires at the end of the GTR franchise in September 2021 so certainly 2 more years left in service.They’re staying for another 15 years at least
