Union Pacific

Union Pacific is an American railroad company.

History
In The Itchy & Scratchy Movie Scratchy is tied to a train track. Itchy tries to get into a train to run over Scratchy, but must get a degree to ride first. Itchy goes off to Union Pacific, studies madly, passes, receives a degree, attends the achievement celebration, applies for a job at Union Pacific and at last hops into a train. Scratchy quickly tries to untie himself, though does not manage in time and is run over. All that remains is Scratchy's severed arms still trying to untangle the rope.

When Lisa did a report about an old Union Pacific railroad for Kidz Newz she said that the "Union Pacific doesn't come by here much anymore" just seconds before a Union Pacific train passed her.

When Bart prank-called Moe in Morse code, Moe sends back, "I'm gonna stick my golden spike in your Central and Union Pacific".
