| 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. The 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.) |
