Xbox Series X Br218 "to The Rescue" Scenario

On Xbox Series X, I want to complete the "To The Rescue" scenario but I can't complete because after I couple to the train, the freight train behind me gets stuck on my return path which prevents me from completing the scenario

 

Simple Open map and delete train that’s in your way

 

I think you can't delete trains in scenario. I thought you could do it only in free roam and timetable mode
