In the RRO dlc, the tracks of the Ennepetalbahn are on the map, but if you try to walk there, you won't be able to go to the end, because there is a blockade. Wouldn't it be nice to go there with the upcoming Vossloh G6 add-on? I think this would upgrade the route a lot, so I hope they will unlock that part of the route.
Well now you can, iˋve created a scenario with a BR 204 starting in Ennepetal on the Ennepetalbahn and going to Hagen Gbf trough the city of Gevelsberg. But the scenery is a bit, lets say creative in some parts I know iˋm doing a bit of a self promotion here, but its an answer to your question, so its okay i guess https://rail-sim.de/forum/filebase/entry/6809-ennepetalbahn
