I would love modern Northern Rail routes with Doncaster, Wakefield Barnsley and Leeds stations included, both Wakefield Westgate and Wakefield Kirkgate. I'd also like to see nottingham too.
Add detail and be more specific. What routes are you suggesting, what rolling stock should be included and could you add some pictures?
Over on TS21 you can get the route between Doncaster, Wakefield and York (Wakefield Lines) but it's subscription only. It has been suggested before for TSW2 as have a lot of routes which include Leeds or Doncaster.
