The route from Berwick to Edinburgh is one of the most scenic in the UK. The stations are Berwick upon Tweed, Dunbar, drem, longniddry, prestonpans, wallyford, musselburgh and Edinburgh Waverley. The route takes around 45 mins to complete on a high speed run. To try and increase the distance I am including the north Berwick branch. Which has one station. North Berwick. The trains The class 91 was built for the ecml and is a icon. It has a top speed of 140mph but is only allowed to go at 125mph. The class 43 is a wonderful locomotive and this type would be fitted with valenta engines. This has a top speed of 125mph. And finally the 158 This would operate the stopping services on this route and has a top speed of 100mph. Let me know your thoughts on this suggestion down below
