I was in Cardiff yesterday and as far as the bus service was concerned NO ONE new anything on which buses were using Greyfriars Road or not, one old lady had been waiting for a Newport bus from before 12 and at 2.20 was told the bus would not be there but would go from Custom House Street via Queen St Station, when she got there the bus drove straight past her, how she got home I haven't a clue. The guy from Cardiff Bus only had the info less than 5 minutes before that it wouldn't be going via Greyfriars.
Transport system in Cardiff is nothing but scandalous.
