Wife's search for husband's 'mind the gap' announcement
10 March 2013 Last updated at 19:03 GMT
A 40 year-old recording of the 'mind the gap' message played on the London Underground will be used once more so the widow of the actor behind the warning can hear his voice.
Oswald Laurence was heard for years on the Northern Line and lastly at Embankment station - where Dr Margaret McCollum would go just to hear her husband's voice after his death.
Transport for London stopped using the message in November, devastating Dr McCollum.
But now, having been "touched" by the widow's story, TfL is planning to bring it back.
