The 'Kirkiebus' no. 70 to Lennoxtown would go 'via Mavis Valley' even in the 1990s! What this meant was a detour off Kirkintilloch Rd, down Balmuildy Rd then back up Hilton Rd to rejoin Kirkintilloch Rd at the Eagle Lodge.
One of my earliest recollections was being on a train that crossed a bridge between two buildings. Thinking back, I'm sure it was the bridge at Glasgow Cross. When did trains stop going into St Enoch? This would have been mid-late 70s
