Hi Viv - actually, now you mention it, neither do I - unless of course it went to the car park? I am positive this is the level where the shops were (I have not got a clue what shops were there originally except, perhaps for Woolworths), and I also cannot visualise another escalator going upwards. Perhaps there was only one there in the original design, that never got built? I remember going to a shop there with my friend, in the far corner, it was a grocery shop, (was it Asda?) probably around 1968/69. Not long after, she moved to Tamworth, and we followed in 1972.
