Sonia Peters was a trainee hairdresser and a casualty of the 1967 train crash in Coronation Street, when a train travelling over the viaduct derailed and crashed into the street. Sonia was buried in the rubble and was already deceased when found by David Barlow. Sonia had attended Bessie Street School with Lucille Hewitt and was the fiancée of PC Jimmie Conway - the couple due to be married the following week.
Her grandmother Elli Jane Peters, awaiting news, sat in the Rovers' snug with Minnie Caldwell, who was also worried about her "missing" friend Ena Sharples. Elli found little comfort in Minnie's reassuring words. She had taken care of Sonia since her mother died when she was two in 1949, as Sonia's father played an almost non-existent role in her life, and was beside herself when she was informed that Sonia was dead.
The inquest into Sonia's death was held later that month and brought a verdict of accidental death.
- The episodes concerning the crash were Episode 667 (8th May 1967), Episode 668 (10th May 1967) and Episode 669 (15th May 1967). Sonia wasn't actually seen, but was referred to.
