I agree with everything your have written Adrian with exception to your last paragraph, for me, the tram would be brilliant! I also think it is worth looking into this idea in more detail.
As for buses in Hereford they are a waste of time. There is only one bus in the mornings from Newton Farm to Holmer and I have to change at Tesco in town to catch it! There are plenty from Newton Farm into town but only one from town to Holmer and that arrives an hour earlier than I need, Have to be at work for 9am. So loads of people moaning that people use cars when they could use public transport but the service just in not there.
