Except that "those cars" will not always be the same - As I understand it, S7s can be turned in service, as C stocks were Which is why the signs are in the first and last cars on the trains. That's OK for Baker Street, where I understand neither the front and rear ones open, but what do the notices say for stations where only the rear, or only the front, stay closed? (I must admit I have yet to travel on an S7)

I had misunderstood the comment to be suggesting notices specific to each station ("these doors will not open at the following stations..........") which would indeed depend not only on which way round the train is, but which way it it going!

Sorry, just out of interest, what is meant by 'turned in service' - I take it you don't simply mean reversing a train to go back in the other direction, as at a terminus for example?

Turned end-for-end. I don't know whether it is still done for S stock, but certain C stock workings were scheduled to run via the south sides of the Minories or Kensington triangles, which meant they would end up back to front. (That is to say, if you take a train from Tower Hill to Barking and then to Liverpool Street, it will end up the opposite way round to one which simply went "round the corner" via Aldgate as a normal Circle service would do). This was done on purpose to even out the wear on the wheels, as those on the inside of the bends on the Circle (left when going anticlockwise) tended to wear faster than those on the outside. A stock also got reversed end-for-end because of the early morning/late evening services running direct between Rickmansworth and Watford. It is for this reason that both A- and C-stock, but not D-stock, had hermaphrodite coupling arrangements: D stock has west end and east end units, and you can only couple an east-ender to a west-ender. (The double-ended units have one end that can only connect to a west end unit, and the other end can only connect to an east end unit)
