| iLocations. Here is the first of two images showing the 19th Street Grade Crossing in Altoona, Pennsylvania, c. 1911. Prominent here is the Pennsylvania Railroad's double-tracked line between Altoona (to the left) and Duncansville (to the right). From 1850 to 1854, this was the mainline between Altoona and Duncansville and the PRR's interchange with the Allegheny Portage Railroad. Visible at the right is the elevated Crossing Gate Tower. The photographer's name and the date are not recorded. |
