This UK woman visits underground station every day to listen to her husband's voice who died in 2007

Some love stories are beyond time and space, and history has witnessed several love stories that became immortal for their exemplary virtues such as sacrifice, unconditional love, and unswerving commitment. A unique story of love and devotion from the United Kingdom has moved the Internet.

Dr Margaret McCollum, a general practitioner from London, has been visiting the Embankment station each day since her husband’s death in 2007. Margaret was married to Oswald Laurence, a RADA graduate and actor. Oswald had recorded the ‘Mind the Gap’ announcement for the northern line in the 1950s.

Margaret and Oswald met in 1992, while he was working for a cruise company in Morocco. They lived together until his death. After his demise, Margaret visits the Embankment tube station every day, just to hear her late husband’s voice.

The chime of ‘Mind the gap’ is quite well-known in the UK, however, nobody fathomed that the depth of the voice meant a lifetime for Margaret. ‘Since he died I would sit and wait for the next train until I heard his voice,’ and explained how the recording helped keep his memory alive,” Margaret was quoted as saying by UNILAD, a UK-based social news portal.

In 2012, when the tube station replaced the audio with a digital system, Margaret was shocked as she could not find her husband’s voice. She inquired about the announcement with the TfL Rail services, however, the authorities told her that they were unable to embed Oswald’s recording on the new system.

After comprehending what the voice meant to Margaret, the rail company arranged a CD of the recording for her.

"We were very touched by her story, so staff tracked down the recording and not only were they able to get a copy of the announcement on CD for her to keep but are also working to restore the announcement at Embankment station," Nigel Holness, London Underground director, was quoted as saying by the BBC.

Margaret had requested the authorities to restore her husband's voice. Her plea was accepted and the rail company decided to restore the 40-year-old announcement audio.

TfL began using the ‘Mind the gap’ announcement in 1969. Initially, it was the voice of sound engineer Peter Lodge; however, over the years several other voices were used.
