This is my opinion but I would really love to see another route in Wales, like Swansea to Carmarthen or Swansea to Cardiff because I would love to see my local town Swansea in TSW6
Would like to see a modern version [2024] of Crewe. I'd do Crewe to Holyhead with trains like the 158, 197, 805, [805 Deluxe Train] 323, [Layered from Manchester Airport Commuter] 390 [Layered from WCML: South London Euston to Milton Keynes] 350/1, [Layered from WCML: South] and the 150/2 [Layered from Cardiff City Network] I think this would be a great route throughout the heart of North Wales and North West England too. I'd expect the 484 would be put into a TfW livery operating the Borderlands line Between Wrexham Central and Bidston and see the TfW 150 to be put into a Northern livery at Chester for trains to Leeds and Manchester Piccadilly. I heard many people like RichyRail has asked for this for the last 2 TSW's. I think this is going to come out soon but not straight away.
No im so sorry but the modern era is not it for that route we need like 2016. ATW Classes 175, 150, 158 & MK3 Sets and the VT Class 221
