Southeastern Pennsylvania Transportation Authority ("SEPTA") is soliciting proposals from qualified consultants for Architectural and Engineering ("A&E") Services for the Design of the Darby Traction Power Substation ("TPSS") Project. The purpose of this project is to provide Architectural and Engineering Services for the design of a new TPSS at SEPTA's Darby Transportation Center to support the increased power demand of the new light rail vehicles, expansion of the 102 Line, and potential charging capabilities. Darby TPSS will be built as part of SEPTA's Trolley Modernization Program. The new substation, which must be completed prior to the introduction of the new trolley fleet to SEPTA's light rail system in 2027, will provide SEPTA the ability to meet the electrical demands of the modern light rail vehicles and provide increased redundancy and operational flexibility. The new DC TPSS will be located on a parcel of SEPTA owned land adjacent to the existing Darby Transportation Center, near the intersection of 9th and Main Streets, in Darby Borough. The substation will have a 630 VDC nominal output and will supply DC traction power to the Route 11 and 13 trolleys and the future extension of the Rt 102 trolley.
