Transcontinental Underground Railroad

The Trans-Continental Underground Railroad is a railroad that travels through New New York, and ends abruptly at the outskirts of Tijuana, after several hours through a tunnel. Bender and Hermes rode it to escape Mom's Killbots, and to find Inspector #5.

Trivia

 * Its name is based on the Underground Railroad, which wasn't an actual railroad, but rather secret routes used by African-American slaves.
