As the title suggests; the Great Western Express route, but set in the modern day, with OHLE and the modern rolling stock.
There was talk of a re-master on a live stream I believe, and it is in the works now as shown in this thread Gwe Remaster: Appreciation And Discussion Thread | Dovetail Games Forums
Would rather see the line recreated in the late 70’s or early 80’s with classic diesel power and Paxman HST’s.
From the early 1970s to the early 1990s, this route had so much more variety as well as a better layout of trackwork. If at any point we get a different version of the route, it absolutely must include ALL of the Thames Valley branches for passenger and freight operations maybe also extended to Newbury and Oxford. Anything less would surely be a travesty.
