Allegheny Portage Railroad Plane No. 2

From 1834 to 1854 this 36-mile line connected Hollidaysburg to Johnstown. The railroad portaged canal boats over the Allegheny Mountains, which formed a barrier to the Pennsylvania canal system. Horses and mules pulled the first trains. Later steam locomotives were used. At the center of the line, Plane No. 2 served as the railroad headquarters. (Dedicated: Sunday, September 11, 1994)
