Major Project Accomplishments

NCTD - Sprinter Main Line Rail


In March 2008, North County Transit District (NCTD) completed a 480 million dollar major new starts project that provided east-west service. The service, “Sprinter” consists of a Light Rail Vehicle (LRV) operating over a 22-mile long rail corridor between Oceanside, Vista, San Marcos and Escondido that was once called the San Diego Northern Railway.

As part of NCTD Systems Engineering firm of choice, Pacific Railway Enterprises, Inc. (PRE) provided support to NCTD on this new start project during construction. PRE’s task included Design Support During Construction (DSDC) and Signal Construction Inspection.

Although PRE was not responsible for developing the signal contract documents, PRE at the request of NCTD performed the DSDC. PRE’s role was to provide support to the Construction Management team and perform field inspection specifically related to rail based systems.

    Project Highlights

  • Savings to project and long term maintenance cost associated with mitigation of traffic congestion in the vicinity of stations.
  • Providing assistance and direction to a signal subcontractor that had little experience in the type systems associated with heavy rail operations. (Note: Sprinter system must conform to FRA requirements to support freight train operations.)
  • Safety enhancements to 35 at-grade highway grade crossing systems including 4-quad gate systems, and pedestrian treatments.

This role was not an easy one considering that PRE did not develop the contract documents and the very structure of a Design-Build “DB” contract makes it difficult to keep constraints on less qualified system installers. Nonetheless PRE accepted the assignment with great enthusiasm. The DB signal contractor installed a Centralized Traffic Control (CTC) signaling system with passing sidings and an operations center to dispatch the trains from a central location in the Escondido Maintenance Facility. The project also included safety improvements to 38 Automatic Highway Warning Systems (AHWS).

PRE staff provided technical guidance and reviewed and approved all of the signal contractor design submittals for over 80 locations. Additionally, PRE responded to over 500 Contractor Requests For Information (RFI’s) again somewhat of a difficult task not being the designer of the original bid documents. PRE provided oversight of the dispatch system installation and commissioning and assisted the CM in negotiations of change orders.

At the recommendation of PRE the first project change order initiated resulted in a savings to the project and long range maintenance costs. The initial design required installation of a Train-to-Wayside Communication (TWC) system that would have required installation of numerous pieces of equipment in the field and on-board systems on the Sprinter vehicles. Installation of this equipment would have added to the expense of the project and long term maintenance of the signal system and Sprinter vehicles.

PRE’s alternative approach allowed “Sprinter” vehicles entering the platform initiate a routine that would activate the downstream AHWS seconds prior to the vehicle leaving the station thus mitigating traffic congestion in the vicinity of stations. PRE provided inspection personnel for all signal related installation and additional personnel to witness the Contractor’s testing and commissioning of the system. In addition, PRE staff assisted in the preparation of CPUC Safety Certification documentation of the system.

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.
