Major Project Accomplishments

NCTD - Positive Train Control


North County Transit District (NCTD) is implementing Positive Train Control (PTC) along their Oceanside subdivision. As part of the contract, PRE completed design for a signal upgrade for PTC at CP Friar as an invitation for bid project.

PRE staff participated in oversight activities related to signal and communications facilities that were impacted by PTC implementation. PRE’s scope included submittal review, Request For Information (RFI) responses, oversight of PTC wayside installations, system testing, field verification and validation, and adjustment to the fiber optic installation projects. PRE attends weekly meetings to support the project and provides field inspection staff. PRE is certified in the Mentum Planet 220 frequency planning for NCTD. PRE staff provided its expertise to reconcile a fiber installation project segment that experienced setbacks and required additional oversight. Going forward PRE has been supporting review of fiber optic relocation work for NCTD when the cable is impacted by new construction. Taking the products selected for NCTD’s PTC wayside install, PRE created the first PTC standard specification for use in the LOSSAN corridor projects. PRE will also incorporate the contractor as built documentation to update the standard maintenance drawings maintained for NCTD for PTC elements.

Client Information



The North San Diego County Transit Development Board (NSDCTDB) was created by California Senate Bill 802 on September 20, 1975. The Board was created to plan, construct and operate, directly, or through a contractor, public transit systems in its area of jurisdiction.

On January 1, 2003, a new state law was enacted (SB 1703) that essentially transferred future transit planning, programming, development and construction to SANDAG, San Diego's regional planning agency. The NSDCTDB, referred to as the North County Transit District (NCTD), continued to operate the BREEZE, COASTER and SPRINTER. In this new role, NCTD continues to provide integrated public transit service within the North San Diego County region.
