| Wye Switches. Here is an original photo that I took at the Wye Switches in Duncansville, Pennsylvania, on 27 August 1962. Shown here (L to R) are Pennsylvania Railroad engines #8566 and #8555. Both are ES-15M road switchers built by GM-EMD and rated at 1,500 horsepower each. #8566 was constructed in September of 1953, while #8555 was built in August of the same year. They've pulled a mixed-cargo freight train down the New Portage Branch line via the Muleshoe Curve and are about to cross US Route 22 on their way into Altoona, where they'll rejoin the mainline at ALTO Tower and proceed to the Eastbound Classification Yards. |
