So now we are on RC Stage I still ended up with 2 versions of Cornish Mainline and Branches. One is called 1930's Cornish Mainline and Branches and the other is called just Cornish Mainline and Branches so what is the difference between the 2 the 1930's one is in gray color box btw??? Also how do we get rid of the old versions if you got a new version ?? Because I also have 2 versions now of Niddertalbahn one is in Gray color box again and one in yellow color
