AFAIK there is only one incorrect "St. James' Park" sign (eastbound,
near the front of the train, by the stairs). Considering that the
LU HQ is above the station, it's remarkable that the sign has never
been replaced.

St. James' Park is the correct way to show it. St James's Park is
incorrect. Its like; I'm going to Chris' House, not I'm going to
Chris's house

But surely you *say* "Chris's house", in which case why not spell it that
way? Although there are some exceptions, it's normal to use 's after
singular names ending in s.

Before you try to lay down the law on the use of apostrophes, you'd better
learn when to put one in "it's".
