After waiting for the northbound CSX M648 to clear up the main, M583 (Nashville,TN-Hamlet,NC) receives a signal to pull out onto the main to begin its work to set out 20 cars for Tullahoma. M585 which was a shuttle job between Radnor Yard and Wauhatchie use to handle the Tullahoma block but with the everlasting changes on CSX, M585 was reprofiles as a daily run-through freight now for Howell Yard in Atlanta which took the Tullahoma block out of it’s train and place it on the long distance freight M583 since it has a long list of places the train has to stop and work now.
