I would love to see Bristol temple meads to Cardiff central using GWR class 158 and the class 150 or even use a class 158 and a class 166 Thankyou
Anything is possible, but we would like to see more detail about the route you would like, along with the rolling stock on the line.
Needs More detail here including a map of the route and it should be familiar to some of the player base because it's part of great western main line from train simulator 21.
