Major Project Accomplishments

Port of Long Beach - Track Realignment at CP Ocean


Improvements to the Pier and specifically CP Ocean Boulevard were identified in the Port of Long Beach (POLB) operational study completed in 2006 involving the San Pedro Bay Ports. This update to a previous study pointed out the need to have a fully functional additional track in-service by 2015 at CP Ocean Blvd. This additional track would streamline the operations between newly configured Pier’s F and B and would support the longer range goals of the POLB planned operations.

In 2011 the POLB contract with PRE through a Prime contract with Jacob’s to develop the design changes required at Control Point (CP) Ocean. The work included adding new dual-controlled power switches to provide greater flexibility to provide for efficient operations between tracks within various Piers for efficient train movement. PRE worked closely with the stakeholder groups to define the absolute needs as well as possible future needs once the Port is operating at planned capacity.

PRE participated in the “brain storming” sessions involving the stakeholders that include Port of Beach (POLB), Pacific Harbor Line (PHL) and other POLB design consultant firms working on the Port’s long range plans. These sessions led to the formation of a workable construction phasing plan that provided the POLB and PHL with the greatest efficiency with lesser impacts on train movement throughout the area.

PRE design efforts were to work within the framework of the existing CP Ocean and to modify the existing circuits to support new signals and switches within the interlocking. Changes included the addition of a temporary “hand thrown” crossover that would allow for efficient movement between the two main line tracks. These temporary phases were necessary because of the construction staging called for at times the majority of the interlocking to be unavailable to the dispatcher or be out-of-service for extended periods of times.

PRE is currently working on the final design submissions and is looking forward to carrying this project into construction and performing Design Services During Construction.
