I've been trying to find out what's planned for the 365s, to no avail
though.

Unlike FCC/TL 319s that are all deployed on current TL services that
remain TL services therefor get replaced by new stock, many FCC/GN
units (the majority in fact if you count 313s in the fleet totals) do
not work services that are intended to run over TL. There is no reason
to suppose 365s will be cascaded anywhere at this moment in time and
we probably won't know until the x-IEP EMU is known and confirmed for
the KL line.

*I cant quite grasp this. Currently there are 15tph trains through the
core in the peak. That the plan is to run 24 ie 9 extra. Several of
these must be coming off the GN. Peterborough and Cambridge feature on
the proposed route maps. Unless there are some spare paths available
on the GN, surely the additional trains through the core must be
mainly extensions/replacements for existing trains operated by
317/365 ? Which means the existing units must be thrown surplus if the
trains through the core are worked by the new fleet. So where are they
going? Or are they to replace the 313's?

Many of the GN trains are currently 4 or 8 cars, units released by
running through the Thameslink route would therefore be available for
lengthening the remaining services to King's Cross to 12 cars and
releasing any remaining class 313s which run into King's Cross for
Moorgate services.


I accept there may be an argument for using IEP to free up paths, but
this would just replace either existing kit or the new units-you still
end up replacing something unless you are providing more or longer
trains.

All this (IEP apart) really begs the question as to why we need any
new rolling stock to complete the Thameslink programme.


Surely the same principles apply now? *The 20 minutes or so to run
through the core being less than the combined time to turn round an
existing service at Kings Cross and an existing service at a Southern
terminal. Why cant existing Electrostars on the Southern lines be
adapted to work north through the core and beyond?

Similarly adapt the 365's to work through.


Because for the 24 tph timetable, trains will need fitting with ETCS.
This will almost certainly be easier if designed into a single new
class than being retro-fitted to the class 319/377 units (and maybe
class 365) currently in use. I don't know how much work would be
needed to use class 365s as dual-voltage as they've only ever worked
on a single voltage at a time.

The money saved by not *buying a fleet of 1200 vehicles would for
example probably pay for a lot of new electrification elsewhere.

But the units cascaded from Thameslink will be used on new
electrification schemes, without these new units would be needed for
the north-west and Paddington schemes.
