Oceanside-Escondido Light Rail Line
San Diego, California

DMJM+HARRIS provided comprehensive design and engineering services for the Oceanside-to-Escondido light rail line project in North San Diego County. Services included railroad operations and analysis, right-of-way mapping, inventory of existing plant, a detailed drainage study, station design, signal and communications design, alternative vehicle analysis and procurement documents, fare collection, maintenance shop design, track design, grade crossing design, and even bikeway design. To help fulfill the environmental impact report requirements, we also conducted a traffic impact analysis for the proposed rail line. That report projected and evaluated traffic conditions with and without the proposed project, and suggested appropriate mitigation measures.

In addition to the rehabilitation of some 21 miles of track and related structures, as well as a new 1.7-mile "loop" alignment on virgin right of way to serve the new California State University campus in San Marcos, the project entailed five new major bridge structures, with spans of 100 to 400 feet; a new bike path along the entire right of way; 15 new stations, many with small pedestrian bridges and overpasses; and a new maintenance shop and yard. The project demanded the attention of DMJM+HARRIS specialists in many disciplines, such as civil engineering, hydraulics and hydrology, structural engineering, architectural design, communications design, railroad engineering, and cost engineering.
