Returning to the original idea ...
Not quite - I gave you a needle in a haystack and I think you have given me a haystack in a needle.
Hmmm - the question as posed was ambi...whatever. And the rider was slanted the other way - unless you do think there are well-known examples of rude words containing station names (and not just innuendos; far too easy).
But back in the sheep-fold, all we've got is
Ashdown.
PS: for personalities floreatting before Beeching, are we allowed the longer list of contemporary station names?
