To make way for the largest expansion in history at Magic Kingdom, the Walt Disney World Railroad is operating under a modified route that excludes Frontierland. The attraction will operate as a shuttle between Main Street station and Fantasyland station only.
As you can see below and in your My Disney Experience app park map, the track has been removed west of Main Street, U.S.A., to show guests that the route only goes east up to the Fantasyland (Storybook Circus) station.
