A Line-OCS System Replacement Project

The A Line-OCS System Replacement Project is a resiliency initiative managed by the Los Angeles County Metropolitan Transportation Authority to protect critical infrastructure against climate change projections. The project scope involves extensive rehabilitation of the overhead contact system (OCS) along the A Line, spanning from Union Station in downtown Los Angeles to the Sierra Madre Station in Pasadena. Key technical requirements include the replacement of all contact wire, hangers, jumpers, contact bridges, and various insulators, including cantilever, contact wire, messenger wire, and section insulators. Additionally, the project will replace span wire registration assemblies, in-span insulation, and termination leads, while upgrading balance weight assemblies to spring tensioner units. A specific structural modification includes converting the Air Break near the Allen Interlocking into an overlap utilizing section insulators. This project is classified as a rehabilitation of existing facilities and has received a Notice of Exemption under Section 15301(d) of the CEQA Guidelines. While the technical specifications and environmental compliance details are clearly defined, specific procurement data such as the contract value, solicitation number, and period of performance are not provided in the current documentation. The project is located within Los Angeles County, California, and is overseen by the Los Angeles County Metropolitan Transportation Authority, with Tom Kefalas serving as the primary administrative contact.
