I shall also follow this build with interest, for 30+yrs I lived just across the other side of the football field. I remember the quarry being worked and rode on Amos several times, the driver was Ted Clarke I cannot rememberthe names of the other two men employed at Bloxham. I think your weigh office is about right Amos lived in a corrugated tin shed, I thought the track was bullhead maybe it was a mixture? Is it 60yrs since the quarry closed? that means I was 8.
There were lots of gate posts and fence straining posts made of those old rails. Were they bridge rails? As kids we used to roam all over the quarry and the station also the fields you were taking photos from!
