Electric Traction

Computer Simulation:

Utilizes the commercially available Energy Management Model (EMM) of an operating traction power system including the trains, substations, OCS or third rail, track and track physical characteristics, operating schedules, station stops, operating track speeds, and loaded to reflect worst case load conditions and all types of emergencies.
