I can see what you are saying about relief in the scenario described.

But what about this scenario: a service runs every 15 min with a mix
of 4car and 8car EMU in random pattern. You approach a station that
service terminates - both 4car and 8car trains terminate and turn back
in a maximum length 8car platform. Not only that, some 8cars turn back
complete on the next service, some 8car detach leaving a 4car behind,
some 4cars run on top that berthed 4car but do not attach, merely turn
back, that berthed 4car may sit there for 45 min, 60 min, 75 min,
whatever, but another arriving 4car may attach to that berthed 8car.
Your approach ascpect is out of site of that platform, due to
curvature.

Would you then expect to have the driver of an arriving 8car relieved
because he accepted the call on only to come into sight and find a 4
car already berthed there when that 8car is booked thus ?

I have seen this happen. Where ? Luton.

Does the driver stop his train short of the entire platform ? Stop
with only cab on for emergency access ? Draw up as far as he can ?
Stop short mid section as soon as he sees the platform is partially
blocked ?

It is even more complex than that to sort out since 319s do not have
SDO and there is no normal passenger gangway between units. So even if
the arriving 8car does run on the platform and berth the front 4car
there is no *normal* access to the rear 4cars except through the
emergency end doors. With 321s youd not even be able to do that.

It took Luton about an hour to sort it all out - as there was no
driver to shift the berthed 4car ahead - this occured in platform 2 at
Luton which is a through loop line, and there is room to berth a 4car
beyond the platform, but the driver of the arriving train - rightly or
wronlgy apparently was unable to leave his partially stranded train to
shunt the other unit out the way - or even couple to it make a 12car
move it that way.

IMHO I would have thought the arriving train would have been
authorised to make a bang road move back to the relevant signal and re-
route to a different platform - but its entirely possible another
train was already there given the 8 tph train pattern at the time.
