As the title suggests, this is one route I'd like to see added more than others (including Hull - Manchester Piccadilly). I use the line often (not as much in 2020 though) and it offers enough variety to be interesting. Whilst mostly passenger, there has been the rare freight train travel on it. With numerous stations and scenery and roughly 45-50 miles, you it offers enough for a single gameplay. It would be set in modern day though, so 3- car Class 170 Turbostar and 2 car Class 158 (sometimes two units together). Edit: I'd also include the routes to the Botanic Garden Depot and King George docks in (both in Hull).
