Around 7am. on that fateful day - on which occurred Scotlands worst mining disaster of the 20th century - the early morning shift had just clocked on and were being carried in a small train of bogies towards the coalface.
The sole survivor of that brief train trip was 50-year-old Big Tam Green, a 6 ft. 4” giant from Marnoch Drive, Glenboig, who later told how he and his mates ran into thick, black, choking smoke.
“Im the luckiest man in the world. I am alive. I have come out of that nightmare down there. I cannot believe that all this has happened in such a short time... that I have lost all my working mates, my friends.”
“It seems to me no time at all since it was seven o'clock this morning and we were all chuckling over a joke as we waited for the cage.”
“As I got aboard the bogie, I smelled fumes - but only slightly. I don't think I gave them much attention at the time.”
“The bogies started to rumble downwards. Suddenly the smoke and fumes were intense. It was almost impossible to breathe. We signalled frantically for the haulage man to take us back up the track. The bogie started moving upwards... the smoke was following. I tried not to breathe.”
“I realised that the situation was desperate. Men were choking all around me but the haulage still kept moving upwards."
