I'm trying to play the Huddersfield line Leeds to Manchester line in free roam, but I just get taken to a empty field with nothing in it when i start the scenario. What am I doing wrong or why isn't the line loading into the free roam?
I don't think the route comes with a Free Roam Scenario So you have to create a Free Roam Scenario by placing any loco/train on a section of track - usually at a station. Then add a Driver Icon and it will be there when you start the Free Roam
You may have accidentally created this yourself. Click on the map, teleport to a station, choose any stock and drop it onto the rails. Add the driver icon, press play, set your points and just drive . You can place as much stock as you like wherever you like, creating a huge sandbox game for yourself.
