| Here is page 15 of an 18-page excerpt from Charles S. Roberts' 1997 book entitled "Triumph I: Altoona To Pitcairn 1846-1996," page 53. Photo and text provide details about the Muleshoe Curve and the Pennsylvania Railroad's New Portage Branch line above Duncansville, Pennsylvania. (In Response To The Author's Question Posed Herein: Yes, this 1892 photo does depict a railroad curve ~ but it's not Duncansville's Muleshoe Curve. Actually, it's located on the PRR's Tyrone Branch line.) |
