SDO?

SDO is normally used to allow one set of doors to be off the
platform,
not an entire coach at each end.

LDO ?

For some NR services two or more coaches can be right off the platform.

On SWT, Clapham Junction, New Milton, Hinton Admiral, Ash Vale, Alton
and of course Bentley (Hants) with room for only 4 coaches.

And I remember taking my bicycle from Banbury to High Wycombe (about
1960) and the train having to be moved to let me get off from the rear
coach with the guard's van.
