When I was a kid I came across a stash of old Newsrail magazines and I have a vague memory of reading that they took old suburban swing door sets onto that line and burnt them.
Many decades later it strikes my adult mind that this would be a pretty weird thing to do. Is my foggy childhood memory correct? If it is, why did they do that rather than just scrapping them at a suburban location?
Bogong, you are correct.
One of my workmates at Thompson's Kelly & Lewis lived at Kingston opposite the station during the 70's and he told me that they would drop the carriages off, then light them up. Brought tears to his eyes back then he said.
If you visit Mark Bau's Victorian Railway's website and find Kingston you will find a photo to confirm this happened.
The last Foundry Manager I had at TKL started his Patternmaking Apprentice at Newport in the early/mid 60's, his first months on the job was to smash all the windows of the carriages, rip out all the metal parts which were squashed by a tractor and then assist putting a chain around the body which the tractor pulled the body off the frame.
