No, I do not subscribe to the Ezine Tramway Monthly, however I did come across this reference about a disaster in Coronation Street. I expect Coros is on UKTV here but to my knowledge it hasn't been on free tv here for many decades. I remember my parents watching it and they then watched an American show called Peyton Place.
At about one minute into the video there is an explosion and just have a look what happens at about 2.30. You can go to the link above and check out how it was made.
