STV has signed a contract with the Tri-County Metropolitan Transportation District of Oregon (TriMet) to spearhead the replacement of 12 traction power substations along the Metropolitan Area Express (MAX) Blue Line.

The MAX Blue Line represents the longest route in TriMet’s light rail network, spanning 33 miles and serving 48 stations between Hillsboro, Beaverton, Portland and Gresham. Originally installed in 1983, the Blue Line’s substations are nearing the end of their expected service lives. By undertaking their replacement, TriMet aims to enhance availability, equipment access, reliability and overall safety, while reducing maintenance costs and the risk of service disruptions.

STV will oversee the substations’ structural, civil and systems design as well as project controls for traction power design and civil site improvements. The firm will also provide overall project management, leading a team of eight consultants.
