Trams

Living in Liverpool like I do, you get use to the fact that the trains are poo, and the buses while frequent often are falling apart and quite uncomfortable (the roads in Liverpool are very bad), but it turns out we are now getting a tram service. Which they have been talking about for ages, but now they have funding. I know that’s not the same as building the service, but for reasons unknown to me. They are building the first tram line to go from Liverpool to Kirkby. Now people who know Liverpool will no doubt be aware that miseryrail already run a train from Liverpool to Kirkby, and while this tram will take a different route. So why o why isn’t the first tram line through an area of Liverpool devoid of a train service?
