This morning my wife and I used the new guided busway from Cambridge to St Ives for the first time. It was excellent with double decker buses with good leather seats, free wi-fi. Being over 60 we get to travel for free. It runs for most of the way on the track of the old St Ives to Cambridge railway line.
St Ives is a pleasant little town by the river (don't confuse with the other one in Cornwall) with some interesting shops. The whole busway was the centre of controversy as it was very late opening. I hope it is successful and attracts lots of customers. See also http://www.thebusway.info/.
