100 % 8-Car Trains-- Power Upgrades


Contribution to Strategic Goals

This pie chart represents how strongly a project is linked to each of Metro's five strategic goals.


This project includes completion of the improvements to the traction-power system to allow the deployment of up to 100% eight car trains. The increase from 6 to 8 cars increases power requirements of each train and therefore the load put on the traction power system increases.


Current traction power supply capacity is not sufficient to support 100% 8-car train operations. Additional transformers, rectifiers, breakers, track feeder cables and negative return cables must be installed to support the power necessary to operate 100% eight car trains. The 50% 8-car train upgrade has been implemented. Further upgrade to 75% and 100% 8-car trains requires additional upgrades to ensure a safe and economical power supply. The upgrades are required to ensure 8-car trains can operate without the risk of an overload to the power system which could cause damage to the power equipment, cabling and/or trains.
