Capacity Modeling Guidebook for Shared-Use Passenger and Freight Rail Operations

TRB’s National Cooperative Highway Research Program (NCHRP) Report 773: Capacity Modeling Guidebook for Shared-Use Passenger and Freight Rail Operations provides state departments of transportation with technical guidance to aid in their understanding of the methods host railroads use to calibrate and apply capacity models. The guidebook examines the modeling processes and results that are used to define, measure, simulate, and evaluate railroad capacity. These models may help determine if adequate capacity exists to support new or increased passenger rail service or if infrastructure improvements may be necessary.
