Because I've ridden on this line irl, and we currently only have 1 Welsh route in TSW, I would like to see the Cambrian Line from Shrewsbury to Aberystwyth and Pwllheli. Total route coverage is quite long at 87.1 miles but the route is incredibly scenic and you have the narrow gauge railways at Aberystwyth and Porthmadog, the unique track layout and location of Dovey Jn and the great feckin big Barmouth bridge just east of Barmouth station. Motive power would have to be the TFW Class 158, modified with Welsh ERTMS signalling, and you could also include a Network Rail Class 97 for some service variation in the form of crew training trips, log trains with the KFA timber wagon, and if you have JustTrains' Class 86 pack, a rail tour to Pwllheli or Aberystwyth with the Class 97 and MK2f stock. The route would be perfectly fine set in the modern day (2020 - present day). Barmouth bridge ^ TFW Class 158 ^ Network Rail Class 97 ^
