I would say 158s and 159 are life expired in 5-10 years time as they are already 34 years old now, as good as they are, they are nearing the end. That said if all the Sprinters don't get replaced in the next decade these will be the last to survive so could outlive their service life.Not sure what other services the class 360's could have been used on? The class 379's though I believe should have gone to Great Northern to release the class 387 units to Southern or South Eastern. This would help with replacement of class 313 fleet with Southern and go towards replacement of class 465 fleet with South Eastern.
As you say you will have class 158 and I suspect class 159 as well becoming life expired in 10 - 15 years time. I would have hoped by then, that there is a dual voltage tri - mode train by that time, that could work 3rd rail dc/OHLE, but also on battery and diesel power in the way that the class 756 works. Ideally it would be British built too by either CAF, Siemens, Hitachi or Alstom.
As well as the class 158/159 units that will need replacing in the next 10 to 15 years, you also have the class 465 fleet, plus class 318, 320 so maybe an order could be made of different versions of the same train to replace all of these types of units?
The DfT denied GN the 379s, ostensibly because 'commuting is not coming back'. That said if the Networkers need to be replaced and ordering new is too costly, then as you say 387 cascades could send the 379s to GN in a few years time.
