No. The 387's are not owned by Southern.
No one is/was saying they are.
The original position on 387/1s was owned by Porterbrook (still are) leased to Southern and sub-leased to FCC and later the Govia TL+ GN successor entity for ~9 months before Southern was rolled into GTR. The original lease period was till later this year.
In a similar way the 25x SE 377/5 and /1 are owned by Porterbrook, leased by Southern (pre GTR) and subleased to SE.
There is plenty of sub-leased stock on the network including SE subleasing some 707s back to SWR.
That doesn’t necessarily mean it won’t be happening altogether… it just means it won’t be happening straight away.
Agreed
After all, isn’t the whole point to bin Southern’s older stock i.e. the 313s and 455s?
It is but GTR
may have been a bit optimistic in terms of estimating likely demand reduction and what they could get away with it terms of service level and train lengths leaving a capacity gap if all the old stock is removed. Demand level recovery on GTR and into large urban areas more generally (nationally) has shown a greater recovery in shorter distance commuting than longer which is problematic for the cunning plan (and bad for industry subsidy requirements).
There is also the need to fit ETCS immenently and an interior refurb was progress will naturally be slower than wished for.
Which is a second good reason apart from Akiem potentially stalling on leasing cost reductions - a good period off lease attracting storage costs helps focus minds. Akiem are more realistic than Macquarie were.
Newer stock needs less maintenance and down time than the 313s/455s hence GTR will be anticipating maintenance cost reductions and fewer new units replacing those leaving.
