Transit Switch Design Analysis (Phase I)
Transit Switch Design Analysis (Phase I)
Report Number: R-071 Volume 2
Transportation Technology Center, Inc.  (TTCI) modeled the performance of Southeastern Pennsylvania Transportation Authority (SEPTA), B-IV cars operating over a SEPTA tangential design spiraled geometry Number 8 lateral turnout, an American Railway Engineering Maintenance-of-Way Association (AREMA) Number 8 lateral turnout with a 13-ft curved switch design, and several variations of these two designs.  The study was designed to determine which switch design features contribute to the good performance and long service life of the SEPTA switches.  These design elements will be applied to current switch design to develop a low-cost,high-performance switch for future use.
