Northern Transpennine Modern Hull To Manchester Would be an amazing route with the Class 802 as the key EMU/DMU on this line and have the class 150 in Northern livery and and have the Northern Transpennine class 185 and the Northern Transpennine class 802 as well for the high speed runs. Northern Transpennine trains is a brand we have been missing from Train Sim World for a long time now and a lot of classes of trains such as the class 185's and more this route would run on the side of the Humber and under the Humber bridge and towards Doncaster. At Doncaster you would have to switch power and go from diesel to electric. From Hull a good estimate is around 85 miles (137 km) to Manchester but since TSW routes are getting longer this would be possible
Northern Transpennine trains isn't a/the brand. It's Transpennine Express. Having said that though, I'd love to see Hull and TPE in the game, although not by going to Manchester and repeating the existing Northern Transpennine route (even if it is a different era) Doncaster to Hull would be nice though, with services operated by Hull Trains, Northern and TPE (between Hull and Selby only)
