Rogers brings a book of trolleys that used to run in city streets a long time ago. He takes the Trolley to the nearby Trolley Museum (the model pan ends in the sky). Joe Brandtner says the Neighborhood Trolley is reminiscent of a 1900 St. Louis Car Co. single truck open car. Rogers enters a 1925 trolley and talks of holding on to a stanchion as a boy. He blows the trolley's whistle. As they look at a 1949 trolley, Brandtner says they identify trolleys by number. They ride in 5326, a city trolley. Brandtner shows the controls at the front of the trolley. He steps on a plunger to ring the trolley bell. Before the return trip, Brandtner has to raise one electric pole and lower another. The control handles now work the other end of the trolley. He allows Rogers to run the control handles on the return trip. Back at the television house, Rogers shows the control panel with which he operates the Trolley.
In the NOM, the Trolley is startled to find another trolley, labeled Express de grandparents, on the tracks in front of the Castle. King Friday summons Officer Clemmons to remove the trolley. Clemmons lifts the Express de grandparents to let the Trolley pass, but he can't place it back on the tracks. The Express de grandparents flies off. Lady Aberlin catches Officer Clemmons looking into the sky. He tells her about the Express de grandparents. That trolley returns to the Castle. Lady Aberlin tries to speak French to Express de grandparents. It flies to the Eiffel Tower. Grand-père says Express de grandparents has a box with a red bell on it. Inside the box is a message: Collette will visit the NOM via Express de grandparents. Lady Aberlin tells the news to Officer Clemmons. King Friday shows her a picture of Prince Tuesday's grandfather.
Back at the television house, Rogers says what many have asked how they can get a trolley. "Why don't you just make one?" he explains, and demonstrates. He makes a trolley from cheese boxes and draws tracks for it on a piece of paper. He talks of his grandparents, and says he hopes to someday be a grandfather.
