Railroad Simulation


L. E. Peabody & Associates, Inc. began modeling railroad operations in the early 1970's. In the early 1970's, trains were represented in time-distance graphs called "string charts." Since that time, technology has advanced exponentially and the models used to simulate the operations of a railroad have grown more and more sophisticated. Today, L. E. Peabody & Associates, Inc. primarily uses the following two different powerful computer software suites to handle this task. Railroad Operations Simulator (ROS) – developed and maintained in-house by L. E. Peabody & Associates, Inc. Rail Traffic Controller (RTC) - developed and maintained by Berkley Simulation Software. L.E. Peabody & Associates, Inc.'s staff are highly trained in these programs and have used them to assist clients in rate case litigation and to conduct various evaluations of actual and proposed rail operations. Common Uses

  • Feasibility studies

  • Development of train sets
Output
  • Observe dispatched trains traversing the system in real-time
  • Review animated results
  • Review dispatch conflicts on a horizon histogram as the simulation is running
  • Observe impact of investment on the network and traffic flow
  • Dispatch Statistics
  • Fuel Consumption
  • Train Miles
  • Delays
  • Train Speeds
  • Locomotive Performance
  • Investment Impact Analysis




Port / Yard Simulation


Rail yards and intermodal ports are complex and dynamic environments that present tremendous managment and planning challenges. We have experience helping clients evaluate and simulate operations for these pivotal locations to determine where efficiency can be improved and costs can be reduced. In addition, these focal points affect other downstream operations and traffic. Our clients utilize our experience and tools to better predict how their port or yard can influence surrounding assets. This foresight can prevent unneccessary mistakes or costs and identify bottlenecks before they happen.
