Cutty Sark For Maritime Greenwich. The front and rear doors do not open.

There are a couple of booked services between Piccadilly and Buxton where 3 units (typically 150s) are coupled for moving stock. When this happens, the rear unit must be completely locked out as the service is too long for most of the Buxton line stations.
I believe Stonehaven is shorter than a HST.
Didn't realise Pendolinos did SDO. I thought they had extended all the platforms.
I'm near positive Haymarket can take a full Pendolino or HST/225 without any problems on both length and positioning.
Lot's up here I can think of:
Beauly
Connon Bridge
Balmossie
Golf Street
Dunkeld & Birnam
Blair Atholl
Dalwhinnie
Newtonmore
Carrbridge
Gleneagles
Dunblane
Falkirk Grahamston
Carnoustie
Inverkeithing
Kirkcaldy
Markinch
Ladybank
Cupar
Leuchars
Points to clarify
-Stations where at least 1 platform renders a calling service; "too long" counts, as long as said service calls at the platform which results in at least 1 passenger door inoperable.
-In the instance of locomotive hauled stock, a station does not qualify as long as all passenger doors are operable on the platform, even if the locomotive over-rides.
-Stations qualify only if there is a scheduled service which overides the calling platform.
What trains are too long for Cupar?
East Coast HST's are too long for Haymarket platform 1.
XC HSTs.
The carriages fit with a bit to spare. About half of one power car hangs off the end.

VTEC advertise it as having a short platform when HST 2+9 call...
I think the last few weren't done as listed above.
Not sure about a Pendolino but HSTs are advertised as being longer than the platform.
Possibly yes, but on SWT it appears the front of the train is always platformed. Happy to be corrected.Feltham has the same level crossing issue, but it is proposed to solve this by closing the crossing altogether and extending the platform.
Could the Datchet problem be solved, if the platform cannot be extended at the other end, by changing the signalling that up trains overrun the platform, clearing the crossing, and SDO not opening the front rather than the back two coaches?
See post #16.How about Sugar Loaf Halt?

As many times as I've boarded or passed through on full length HSTs I've never noticed an issue at Gleneagles, Kirkcaldy or Leuchars. Grahamston and Inverkeithing are well known as short on the other hand.
Loch Eil Outward Bound is a short platform which is operated on local (rear) door only
There is a station between Three Bridges and Hassocks which cannot take a 12 car Class 700 from what I can recall
Quite a number of stations on the line to Pembroke Dock (including the terminus!) cannot take a full HST set when it runs that way in summer
Meadowhall when a 2x3 car 185 calls. This will be happening even more when South Transpennine gets more doubled up services.
