Railroad Simulation

L. E. Peabody & Associates, Inc. has been modeling railroad operations in one model or another since 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 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.
