Leaving the northern show building, the T.T.A. passes the Tomorrowland Speedway and TRON Lightcycle/Run. Afterwards, the T.T.A. crosses the Walt Disney World Railroad tracks and pass through a switch, which leads to the ride's storage and maintenance bays as they make a right turn to enter Space Mountain. Inside Space Mountain, the trains then make a left turn and pass in between the lift hills of the roller coaster tracks. The vehicles then pass two lighted signs reading "Starport: Seven Five" (an oblique reference to the opening year of the attraction), before open space to the left allows a view down into the post-show. After the view of the post-show, the track makes a right turn, wrapping around the Omega track's loading station, and travels along the back side of the dome, which is in complete pitch black darkness. It is possible to look up and see the projections from the ride and the tracks. The trains exit, merging with the storage track, and run along the outside of the dome to return to the railroad bridge. The Space Mountain segment of the TTA has gained heavy notoriety among park guests for offering the only accessible view of Space Mountain when the dome's interior work lights are on. Because the two attractions have separate operating systems, the TTA does not have to stop during Space Mountain breakdowns, so guests riding the TTA when the work lights are on get a rare illuminated look at the roller coaster tracks.
