I wonder if anyone can remember when this started from? I can remember in the late 1970s my gran not being able to use her (then Tyne and Wear) concessionary pass on the "rush hour" on a late afternoon. I think it has always been that the pass couldn't be used before 9.30am but there was also a time when at a certain point on the afternoon they couldn't be used either. Can anyone remember what the afternoon times were when the pass couldn't be used and also what year it changed where passes could be used at any time after 9.30am?
