Traction power analysis, rail simulation, operations analysis

SYSTRA prepared a service evaluation study of the entire WMATA traction power system that included the Red, Blue, Orange, Yellow, and Green lines. SYSTRA used our proprietary RAILSIM® software to perform a load flow simulation to model the traction power system.

This study was used to ensure that trains have suitable electrical power to meet operational requirements and verify that the wayside distribution system is not overloaded by the electrical demands of revenue operations.

The study determined that modifications to the system were required to support the operation of eight-car trains, operating with 120-second headways, using WMATA civil alignment, design criteria requirements, vehicle technical data, operational data, and wayside distribution data.
