Signals on the end of platform - and need these days?

I'm very used to seeing signals on the ends of platforms - indeed I can't recall any station that didn't have then in my youth. But I suspect that even in those days they were there for historic reasons to some extent - that's were the operating blocks were, and it was useful to leave it that way because a fast passenger train could pull up behind a slower loose coupled freight, and perform its station duties while waiting for the line to clear.

But, these days, is there any such requirement - to maintain signals on the end of established platforms, or indeed to add signals at the platorm end should a new station be built in the middle of a double tracked section?

No.  The principle requirement is to satisfy the headway (spacing measured in time between trains at a particular point) followed by signal spacing distances (dependent on line speed and gradient).

Excellent - good to have it confirmed.
