The Horseshoe Curve s construction impacted railroad design and development for mountainous terrain everywhere, enabling access to coal and other raw materials essential for the industrial age.
This landmark, located just west of Altoona, opened to traffic on February 15, 1854, and it enabled a railroad line to climb the Allegheny Mountains and the eastern continental divide.
