| 摘要： | A study has been made for the North San Diego County Transit Development Board of the implementation of passenger rail service to an existing alignment that currently provides infrequent, low-speed, diesel-powered freight service over a 35.2-km (22-mi) right-of-way. At issue were the relative merits of the use of diesel-powered and electric-powered vehicles in providing superior service to a bus system currently in operation. Such performance analysis requires detailed definition of the alignment as well as the characteristics of potentially applicable vehicles. To provide the requisite data on the alignment, the physical characteristics were digitized, including curves, grades, tangent sections, and the location of station sites, in a form suitable for use as input to a computer simulation. A worldwide survey provided the requisite data on several diesel-powered and electric-powered passenger vehicles. Five potentially applicable vehicles (two diesel and three electric) were selected for the simulation process. Results of the simulation activity included speed and time versus distance profiles, energy utilization, and percentage of time at various throttle (power) settings. The simulation results showed that, on this specific alignment, there is little advantage to the use of electric-powered units over diesel-powered units. The reasons for this result were identified from the simulation data and are discussed in the body of this paper. |
