The Northern line platforms at Embankment are curved, and there is certainly a gap that needs to be minded! In 2013, they re-instated an old announcement by the late actor and voice artist Oswald Laurence, after an appeal from his widow, for whom Embankment is her local station.
Temple
Then called The Temple
