The study considers the detailed sequence and scheduling in classification yards and their impacts on yard capacities simulate typical freight railroad terminals, and statistically analyses of the historical and simulated data regarding dwell-time and traffic flows. Approach and Methodology The team developed optimization models to investigate three sequencing decisions are at the areas inspection, hump, and assembly.
