| Wye Switches. Here is an original photo that I took of a Pennsylvania Railroad train at the Wye Switches in Duncansville, Pennsylvania, on 31 August 1960. Shown here is PRR engine #9394, an ES-12 built by EMD in 1950 and rated at 1,200 horsepower. It is pushing a string of gondolas past WYE Tower toward the Hollidaysburg Yards. Note the dwarf signal in the foreground. |
