| Wye Switches. Here is an original photo that I took of a Pennsylvania Railroad train at the Wye Switches in Duncansville, Pennsylvania, on 5 October 1964. Shown here is PRR engine #8564, an ES-15M built by EMD in 1953 and rated at 1,500 horsepower. It is pulling a 34-car freight train from the Altoona Yards to the Hollidaysburg Yards. The caboose is #477632. The fireman has just received train orders from the man at WYE Tower, not shown at right. When the end of the train and the caboose reach this point, the conductor also receives orders by the same means. |
