Granite to Upgrade Perris South Metrolink Station and Layover Facility to Boost Rail Capacity and Reliability

Key Terms

at-grade crossing technical

An at-grade crossing is a place where a roadway, pedestrian path, or another transportation route meets and crosses railroad tracks on the same level rather than using a bridge or tunnel. For investors, these crossings matter because they concentrate safety, liability and traffic-delay risks—similar to busy intersections where collisions can occur—affecting operating costs, insurance, regulatory scrutiny and the potential for costly upgrades or legal exposure.

layover facility technical

A layover facility is a temporary holding site where goods, equipment, or people are kept between stages of transport or processing — think of it as a waiting room for shipments. For investors, such facilities matter because they affect how quickly products reach customers, how much inventory and handling costs a company carries, and the risk of delays or regulatory inspections that can squeeze margins or slow revenue recognition.

bidirectional peak service technical

A bidirectional peak service is a capability in energy systems where equipment can both draw extra power from the grid during low-cost periods and send power back to the grid during high-demand peaks, like a home battery that charges overnight and discharges during a heat wave. Investors care because it creates new revenue streams, reduces utility peak charges, and changes the value proposition for batteries, electric vehicles, and grid operators by turning stored energy into a tradable, time-shifted asset.

greenhouse gas emissions medical

Greenhouse gas emissions are the gases a company releases into the air—like carbon dioxide or methane—that trap heat in the atmosphere and contribute to global warming. For investors, these emissions matter because they can lead to higher regulatory costs, fines, shifting consumer preferences, and physical risks (like supply-chain disruptions), or create opportunities in low-carbon products; think of emissions as a company’s climate footprint that can affect future profits and value.

commuter rail technical

Commuter rail is a passenger train service that runs between suburban or outlying residential areas and a central city, typically timed for morning and evening work commutes and covering longer distances than urban subways. Investors care because ridership, fare rules, government subsidies, and capital spending on tracks and stations affect revenue and operating costs, while demand for commuter rail often signals broader trends in local real estate, employment, and public infrastructure investment.

WATSONVILLE, Calif.--(BUSINESS WIRE)-- Granite (NYSE:GVA) has been selected to transform the Perris South Metrolink Station and Layover Facility Project, an initiative aimed at improving service reliability and addressing increased commuter demand along the State Route 91/Perris Valley Line in Riverside County, California. The Riverside County Transportation Commission (RCTC) has awarded an approximately $24 million contract for this project. Funding will be sourced locally and reflected in Granite’s fourth quarter CAP.

Currently operating as a single-track terminus, the station faces operational constraints that limit train movements and create service bottlenecks. This project will convert Perris South into a high-capacity, flexible hub that supports bidirectional peak service and sustainable growth in Riverside County.

“This project builds on our successful partnership with RCTC and Metrolink and leverages Granite’s core strengths in heavy civil construction and rail,” said Granite Vice President of Regional Operations, Bill Moore. "With our recent completion of a comparable project only 13 miles away at March Field Station in Moreno Valley, we are uniquely equipped to address the expanding commuter rail requirements of the region."

Key Project Features:

• Second Passenger Platform & Track: Adds a second boarding platform and approximately 1,100–1,200 feet of new station track, enabling two trains to load/unload simultaneously and maintain operations if one train is out of service.
• Platform Extension: Lengthens the existing platform to accommodate eight-car Metrolink trains and upgrades passenger amenities, including canopies, electronic displays, and emergency phones.
• Pedestrian Safety Enhancements: Introduces a new at-grade crossing with active warning gates and flashing lights for safe access to the second platform.
• Layover Facility Expansion: Adds a fourth layover track and new switching infrastructure, allowing more trains to be stored overnight and improving operational flexibility.

By improving rail capacity and reliability, this project offers a viable alternative to congested freeway corridors, reducing greenhouse gas emissions and supporting sustainable growth in the Inland Empire. It also represents a significant strategic win for Granite, reinforcing its commitment to expanding in both the rail end market and the Inland Empire region.
