Except that the National Rail Contract for TSGN shows the lease on the 387/1s expiring on 31 March 2028:

There lots of possible options for why this tender has been published as the cascade alternatives are numerous. Could there be an intent to (finally) cancel the Class 701 order and this is a way of getting stock in to release 707s back to SWR?
Of course, it might not be the 379s that are a given for any extra stock: Porterbrook can offer 350/2s - indeed you could use the 37x350/2s to release all the 387s on GN, thus making the GN (and Hornsey depot) a completely Siemens operation.
What do you do about the class 171, 377/2, 377/3 and class 700 units all of which have a scheduled lease expiry of 31st March 2028.
I notice that class class 717 only runs until 30th September 2023. Does that mean that GTR should be looking for replacements for the class 717 units?
I have not fully read the PDF
https://assets.publishing.service.g...ilway-limited-2022-national-rail-contract.pdf but I would be surprised if there is not an automatic renewal of the lease for the class 717 units for at least another 5 years and the same with the class 377/378 units when expiry comes up in 2028.
I also suspect that the class 701 units will enter revenue service this year and with half the fleet now having been built, i think it would be more costly to cancel the order than to see the class 701 enter revenue service. Hence, I do not see the class 707 units going back to SWR. I still expect that by the end of the year that the class 707 units with SWR will go to South Eastern.
379 > 387 > 377 > 465 > 707 > 455
Whilst the class 379's might replace the class 387's with Great Northern and so the 387's then go to Southern, which releases class 377 units to South Eastern, I do not see class 465 replacing class 707 units at South Eastern and I also do not see class 707 units replacing class 455 units at SWR. In fact I would say that it will be class 701 units that replace class 455 units as originally planned.
What nobody is thinking about in the replacement process starting with the class 379 above,, is what is to happen with the class 458 units? What is the expiry date for the lease on the class 444/450 with SWR?
