This project is rehabilitating the existing three cycloconverter type static frequency converters that are located in a facility adjacent to SEPTA's Wayne Junction Substation. It is also adding a fourth frequency converter to the facility. The frequency converters change the 60 Hz power provided by PECO to the 25 Hz power used by the Regional Rail lines. The first phase of the project, currently underway, involves a condition assessment of the existing facilities, an evaluation of available converter upgrade technologies, and a cost benefit analysis of the rehabilitation alternatives. Subsequent phases will include final design and construction.
