TriMet, Portland to Milwaukie Light Rail – Portland, OR
The Portland-Milwaukie Light Rail Project travels 7.3 miles, connecting Portland State University in downtown Portland, inner Southeast Portland, Milwaukie and north Clackamas County. MAX service on the alignment began in September 2015. As a member of the LTK Systems Engineering team, Elcon was responsible for preliminary and final design of the traction power system including six 1MW rectifier substations, and one super capacitor energy storage substation. Elcon was also responsible for the traction electrification preliminary design for the Ruby O&M Yard and Shop expansions to accommodate additional light rail vehicles required for the Milwaukie extension. Elcon also provided conceptual track, pedestrian, and navigational lighting design for Tilikum Crossing.
Sound Transit, South 200th Link Extension Design-Build – Seattle, WA
This project included a 1.6-mile, elevated guideway and station. This extension coincided with the opening of light rail from downtown Seattle to Capitol Hill and the University of Washington in 2016, resulting in a system that is over 20 miles long and acting as a catalyst for private development in communities south of the Airport, as well as improving access to the regional transit system all around.
Elcon was the Systems Engineering consultant for the design-build team responsible for preliminary design for multiple systems elements of this project which covers 1.6 miles of elevated double-track guideway. Final systems design was done by the systems vendors. 
Responsibilities included traction power design, train controls, communication / SCADA, and systems integration. In addition to the systems design work, Elcon designed the passenger station electrical, lighting, public address, CCTV, and fire alarm systems. Elcon also provided construction management support services including shop drawing submittal review, field acceptance testing, and system integration testing.
The Operations Maintenance Facility East (OMFE) is a design-build project by Sound Transit for the construction of a new light rail operations and maintenance facility in the City of Bellevue to support the region’s growing light rail fleet. By the year 2024, the light rail system is projected to more than double in size and the light rail fleet more than triple in vehicles. As part of this Link extension program, Elcon provided the design for a complete traction power substation and the Overhead Contact System (OCS) for the OMFE Yard & Shop facilities, including the design of raceway, structure, duct bank, OCS pole and supports. The design included plans, elevations, details and schedules fully executed in Revit.

SDOT, RapidRide BRT Electrification – Seattle, WA
In order to increase mobility options throughout the city, King County Metro’s Rapidride is expanding their existing three lines to a total of ten corridors. Elcon is currently working on two corridors identified in the Seattle Transit Master Plan and further developed by the RapidRide including Downtown Seattle to Eastlake to Roosevelt and Downtown Seattle to Mt Baker to Rainier Beach.
For these projects, Elcon prepared the project design basis memorandum (DBM) for traction power substation (TPSS) and overhead contact system (OCS); performed voltage drop and load analysis for confirming new traction power substation; assisted SDOT and the design team with preparing a TPSS siting report; prepared preliminary OCS layout plans, and prepared preliminary TPSS drawings including single-line, layout & utility interface.
