Hey! To use off the rails mode in the scenario planner: Go to the scenario planner/maker from East Coastway Follow the steps to make the route in East Coastway(Stations,Trains) You might only have the options of using the original trains and to fix this, go to the specific settings for driver/passenger/off the rails and enable off the rails. I think this will enable you to pick trains from other routes but spawn them in East Coastway. Thanks! Hope this helps.
