Too far back for me however, I've spent the weekend with my mum who does remember the Trolley Busses, the idea would seem very good to have something like this again but if you look at the video, the busses had to share the roads with Cars I'd be very favourable to monorail, tram type transport into the centre with 4 main lines, east, west, north and south but no cars on the lines but this is Wales and unless it benefits the politicians very little gets off the ground after the initial press fanfare, incidentally I've been a little south of Bristol over the weekend, 20MPH is also applicable to various roads over there, not a blanket rule yet and the Wurzels aren't too happy as its being phased in.
