here is another visual suggestion! small route, I know, but can be one developed to a high standard, like niddertalbahn, and is for players who want a more relaxing branch line experience The Loco for this route is the Class 118 DMU, a DMU commonly used in the 80s Around Devon and Cornwall, Also Features some nice scenery, such as the tamar bridge and calstock viaduct
These custom route maps are made by me on Microsoft paint, I get openrailwaymaps . Org and screenshot the selected route, I then take it to ms paint, create a new layer and just sketch over the line
