About Project

Provided an experienced Track and Systems Project Manager and technical support team to identify, evaluate and report on SCRRA's systemwide rehabilitation needs. Prepare deliverables focusing on the key track components; assess condition, prioritize, estimate costs and develop schedule for next 20 years (emphasizing and focusing on next 5 years) for replacement and renewal utilizing SCRRA requirements, current best industry practices, subject matter experts, and existing SCRRA documents (i.e, track charts) assessments and assessment tools (i.e. rail head scans, geometry runs, inspection reports, etc.).

Analyzed current operation to determine the life cycle of the assets and evaluate work impact to current and future SCRRA operations if projects are not completed. The list of prioritized and scheduled projects will include annual estimate expenditures sorted by subdivision and member agency (County) and LOSSAN corridor.

Project Scope, Successes

    Pacific Railway Enterprises, Inc. (PRE) was the primary systems subconsultant that developed the original Metrolink Infrastructure Rehabilitation Plan (MIRP) in 2017. Performing this task, PRE evaluated the entire Metrolink system, cataloging all systems components at every field site. Leveraging nearly thirty years of Metrolink experience, PRE was able to accurately determine the age of these components and precisely forecast their remaining useful life expectancy based on industry guidelines. Using this data, PRE then developed an accurate cost for equipment replacement and its installation.

    Since its development, this data has been used by Metrolink staff to enable it to determine annual rehabilitation budgets and funding requests. To date, these forecasts have been accurate when weighed against actual project expenditures and have proven to be an invaluable tool for utilizing scarce Member Agency resources.

    The next iteration of the MIRP is important to maintain its usefulness in determining the state of good repair costs for systems replacement. Since 2017 Metrolink has undergone many changes that are not reflected within the original MIRP. Among these changes are the evolution of standard equipment used by Metrolink including the global escalation in material costs that have been realized within the last eighteen months. Additionally, Metrolink has performed, or is planning in the near-term, major capital projects that will require updates to the MIRP to maintain system-wide accuracy within the document. Lastly, Metrolink systems have undergone substantial changes since 2017. These changes include vital fiber infrastructures and other new systems that include wireless crossing station inhibit equipment and crossings equipped with vital radar vehicle detection systems. All these differences within the Metrolink system need to be accurately defined, forecasted and estimated to continue the usefulness of the original MIRP document.
