The tram crash
Coronation Street loves a bit of drama, and the show’s special live episode in 2010 to mark its 50th anniversary delivered it aplenty. In the aftermath of a huge tram crash due to a gas explosion, Ashley Peacock died, Peter Barlow and Leanne Battersby tied the knot in an emergency wedding and Fiz gave birth prematurely to daughter Hope. More than £1 million was spent on the gripping, tension-filled episode.
