STV signed contracts with California’s San Mateo County Transit District (SamTrans) to spearhead crucial battery-electric bus (BEB) charging infrastructure upgrades at the District’s South Base Maintenance and Bus Yard and Portland, Ore.’s TriMet to spearhead the replacement of 12 traction power substations along the District’s Metropolitan Area Express (MAX) Blue Line.
The SamTrans BEB Transition
The agency recently procured 37 BEBs to replace end-of-life diesel buses, prompting the urgent need for charging infrastructure at its South Base division.

The project is a key element of SamTrans’ Innovative Clean Transit Plan, which guides the District’s transition to a 100% zero-emission fleet.
Aiming to establish a total of 147 bus charging stations at South Base, the ambitious endeavor will be executed in two phases, with Phase 1 focusing on the first 37 stations and Phase 2 incorporating the remaining 110 stations.
STV will provide comprehensive engineering and architectural design services for all 147 charging stations, along with charging infrastructure, transit operations, maintenance equipment, and transit technology.
STV’s SamTrans Contract
STV secured this project as its first task order under its current six-year general engineering on-call contract with SamTrans, awarded in June 2023.
The project represents an integral component of California’s broader efforts to advance zero-emission transportation and combat climate change.

TriMet’s MAX Blue Line Project
The MAX Blue Line represents the longest route in TriMet’s light rail network, spanning approximately 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 ongoing 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.
