TRANSIT & RAIL PROJECTS
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, OMFE Light Rail Facility Traction Electrification – Seattle, WA
Sound Transit currently owns and operates 62 light rail vehicles (LRV) and to support the Link extension program will have expanded to a total fleet size of 184 LRVs by the year 2023. As part of this extension program, Elcon performed traction power system design including traction power substations, overhead contact system and corrosion control for this design-build project for the construction of a new light rail operations and maintenance facility east (OMFE) in support of Sound Transit’s system expansion. The OMFE site is approximately 28 acres located in the City of Bellevue, bounded by the Eastside Rail Corridor on the west and 120th Avenue NE on the east, SR 520 to the north and NE 12th Street to the south.
Seattle Center Monorail, Electrical Upgrade ProjectS – Seattle, WA
The purpose of this project was to provide design related to upgrades, maintenance, repairs to electrical systems, and support for feasibility studies to the Seattle Center Monorail. Elcon performed calculations and risk analysis, specified components, created drawings, and wrote specifications for upgrades to electrical systems that are part of the Seattle Center Monorail. Specific projects included:
Upgrades to the 700VDC system
Updates to Westlake Center and Seattle Center electrical rooms (updating PLCs, uninterruptible power supplies, annunciator panel, and other components; design of a new HVAC system; emergency lighting; new fire alarm system, and new security alarm system) 
Remote status monitoring of trains and station equipment 
Feasibility study for new propulsion system on trains 
Electrical design support for Westlake Center redesign feasibility study 
Electrical design support when reconfiguring Monorail platforms and offices 
Updated lighting in trains, stations, and other Monorail facilities 

SDOT, Rapid Ride Bus Electrification Program – 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.
