All routes and trainsets MUST be installed outside of the Open Rails folder structure. If within the OR folders they will get deleted when you update OR. Make a new root folder and name it whatever you like, then move the Global, Routes, Sound and Trains folders into the new root folder. Then you can add this new content into Open Rails by using the Content tab in Options. Once that is done you can select route and activity using the drop down selectors.
