The use of regeneration as an energy conservation strategy was studied on the Delaware River Port Authority's Lindenwold Line (PATCO) and the Port Authority of Allegheny County (PAT) Castle-Shannon Trolley Line. These transit systems are quite different from each other in both operating and physical characteristics; the former characteristic of a commuter railroad and the latter a light rail vehicle system. The energy management simulation model, developed at Carnegie-Mellon University over the past two years, was used to realistically duplicate the operation of the systems under conditions of no regeneration and regeneration with both natural and assured receptivity. Although these two systems differ physically and operationally, energy savings on a percent basis under conditions of assured receptivity without on-board storage are rather similar--PATCO (28-32%), PAT (30-35%). On-board storage presents less savings--PATCO (25%), PAT (23%)--principally because of the additional weight required of the storage devices and associated control. Under conditions of natural receptivity, savings are smaller--PATCO (5-9%), PAT (10-12%). There are so many physical and operational parameters in a transit system which can affect the energy savings upon application of regeneration, that it is both necessary and desirable to do site-specific studies of this type when planning regeneration capability for either a new or existing transit system.
