As the title- is there anywhere where a terminating train only opens some doors?
I'm sure they must exist, but I can't think of any.

Is there anywhere that SDO is used at a terminus?

Sheringham used to be with 3 Car 170s but no longer required with a longer platform built to accommodate 3 and 4 car 755s

Maybe the Far North Line , The Kyle Line and and the WHL?
Not sure about everywhere, but Ft William and Mallaig are normally able to take the full train.

Leeds when they accidentally put too long a train into P17.

It was for many years but changed to simply de-selecting the rear coach of a 3-car around 2017. Drivers had to wait for the guard to release the doors before shutting their desk down & removing drivers key.

They didn’t lock the vehicle as far as I know but did use SDO

I seem to remember at one point just after they put 450s on the Lymington Branch line, the rear two cars were locked out of use for the entire journey so technically would have been SDO at Lymington Pier. Not sure if they still do that.

Definitely not, Lymington Town platform was extended shortly after 450s entered full time service.
Bedwyn - Doors 1-9 only on a 5-car IET. Not normally an issue if first class at London end as door 10 is a crew door in the kitchen, but are frequently in reverse formation, in which case door 10 would be at the end of coach A.
Oxford - Doors 3-20 only on a 10-car IET if terminating in platform 3 from London.

At Corby the buffet crew door is sometimes the only door opened. This is so that the Revenue Protection Officers can check every single ticket before boarding, there has been a lot of fare evasion and staff assaults in that area I'm told.

At Lincoln only 5 cars of an IEP. The 2 services scheduled for 9 are SDO.

Skipton is SDO on Coaches A and B for the daily 9-car 80x from London King's Cross.
(Coach B used to be locked out completely when this working was 91/Mk4.)

That's laughable, the bay was purpose-built for them and the paint hasn't even dried yet...

Trains don't get long enough to test (certainly not on the North Highland Lines).

Ore can only accommodate 4 cars, so Southern services formed of 8 coaches terminating there (plus peak-time Southeastern services) use SDO.

Pembroke Dock (summer weekend only) used to when HSTs operated there, as did Frome for HSTs (and now IETs) for the 2-a-day terminators.
Both of which were country end 4 coaches if I remember correctly.

Meridian Water station was built new last year with three platforms including a terminus bay which are max 8x20m stock. Once 720s arrive there will be no services operating there 8x20m. We are promised that all peak services will be 10x720, so only rear doors will open at MW. The masterful planners of the Stratford - TottHale - Meridian Water enhancements built the new platform at Tott Hale max 8x20m even though the new platform is the opposite face of the existing up 12x20m platforms, so it will be the front doors that open there, admittedly with some overlap in the middle.

The bay was extended but once the 345s can run to Heathrow the bay at Hayes won't see that much use (as I would imagine the half hourly Hayes shuttle will extend to Heathrow).
Isn't there some platforms at Victoria (South Eastern side) which can't handle 12 coach sets without SDO?

Was the original question really about SDO at a proper “terminus”; ie trains running up to a set of buffers? If a train needs SDO to stop at a through platform that it then runs through empty, then that’s a slightly easier situation entirely to an example like say Alton. (As mentioned earlier in post #4.)
The key thing there is that when the new front cab is activated, it’s way off the platform end, so the ASDO system now has to deal with inhibiting the front carriages, which were the back carriages on arrival. I’m not sure if the doors stay released while this happens, perhaps there’s someone here who works on that route?

a) it should only be few months before the Hayes Shuttle is extended
b) 3-6 & 8 at Victoria
not 100% sure on Alton but I would imagine procedure will be the same for turn back at Fratton and Portsmouth Harbour platform 1. Driver keeps their key on, door release by guard. ASDO operates as expected, driver keys off. Driver changes ends and keys on. If doors are closed and reopened (runner with a buggy etc) then ASDO should remember to only open the accommodated coaches however general instruction is local door only. In the event of an emergency switch off or unit reboot it’s local door only full stop.
