30 Railroad Tunnels That Cut Through American Mountains, Then Were Sealed

America’s mountains are filled with railroad tunnels that once carried coal, timber, passengers, and freight through some of the country’s toughest terrain. Many were later abandoned as rail routes changed, tunnels were bypassed, or entire lines disappeared. This video explores 30 forgotten railroad tunnels, the engineering challenges behind them, and what happened after these underground routes were sealed or left behind. #RailroadHistory #RailroadTunnels #AmericanHistory #Trains #Railroads #IndustrialHistory #ForgottenAmerica #railwayhistory 📺 Watch the entire video for more information! 💼 Business Inquiries and Contact • For business inquiries, copyright matters or other inquiries please contact us ❓ Copyright Questions • If you have any copyright questions or issues you can contact us. ⚠️ Copyright Disclaimers • We use images and content in accordance with the YouTube Fair Use copyright guidelines • Section 107 of the U.S. Copyright Act states: “Notwithstanding the provisions of sections 106 and 106A, the fair use of a copyrighted work, including such use by reproduction in copies or phonorecords or by any other means specified by that section, for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright.” • This video could contain certain copyrighted video clips, pictures, or photographs that were not specifically authorized to be used by the copyright holder(s), but which we believe in good faith are protected by federal law and the fair use doctrine for one or more of the reasons noted above.
