The Southeastern Pennsylvania Transportation Authority (SEPTA) will design and contract for the engineering, manufacture, testing, and installation of a new microprocessor-based propulsion system for each railcar in the Silverliner IV fleet. The new system will retain the existing traction motors, power electronics, major contractors and signal inputs. Circuit boards in the propulsion, braking and wheel slip circuits will be replaced. A fault indicator and diagnostic system will be installed. Phase 1 includes prototype testing and evaluation of the new system in one railcar. Phase 2 involves the acquisition of equipment and the installation of the system, in 77 cars. Phases 3 and 4 consist of installation of the system in the remaining 154 Silverliner IV cars. All phases of this research project will be documented in a final report. This is congressionally mandated project. |
