The computer model described in this paper simulates trailer handlings in railway top-lift piggyback terminals. It allows a fast and accurate evaluation of operating trade-offs by quantifying the use of tracks, storage areas, cranes, and tractors. The input comprises key physical characteristics, machine schedules, and train and trailer arrivals and departures according to specified distributions. Output tables describe the machine time spent in loading, unloading, traveling, or idling, and they also describe an hourly distribution of cars on each track and trailers in storage. Time-distance charts of machine positions on each track give a detailed log of operations performed for each trailer. The simulation has been used to evaluate modifications to existing terminals and for the design of proposed terminals. It has general applicability to a wide variety of terminal configurations, equipment types and speeds, and traffic volumes. It is written in Simscript 11.5 and requires 400-600 K of core and 1-5 sec/simulated day to execute, depending on the size of traffic.
