Sepulveda Transit Corridor Partners (STCP) is proposing two heavy rail options: 

• Alternative 4: A mix of underground and aboveground sections. 
• Alternative 5: Almost entirely underground, except for a short aboveground section near the Van Nuys Station. 

Both alternatives include 8 strategically located stations, including one at UCLA, and provide a 20-minute ride from the Valley to the Westside. 

Heavy rail transit runs on dual tracks and is the backbone of high-capacity metro systems in the U.S. and worldwide. It is already in use by Metro on the Metro Red Line (B Line).

STCP’s proposed heavy rail alternatives are built to last for over a century with regular maintenance and upgrades. Because they run mostly or entirely underground, and provide a fast, reliable transit option for Angelenos.

Travel Times and Speed: With trains reaching up to 70 mph and arriving as frequently as every 90 seconds to 2.5 minutes at peak operations, travel times will be the fastest in LA history:

• Valley to Westside – 20 minutes
• Van Nuys to Expo Line – 20 minutes
• Westwood Blvd. to Ventura Blvd. – 6.5 minutes
• Wilshire/Westwood to Santa Monica Blvd – under 1.5 minutes 

8 Convenient Stations: Alternatives 4 and 5 include eight stations strategically placed for easy access, allowing riders to park and board the train in just a few minutes. They are designed to accommodate high ridership numbers in each area. 

Reduce Nearby Congestion: Stations along the route offer quick connections to the D, E, and G Lines—giving commuters faster and more flexible ways to get where they need to go, which will help alleviate nearby traffic congestion. 

Designed to Minimize Disruption: Alternatives 4 and 5’s tunnel design and construction approach are intended to protect against aboveground disruption. The stations feature a compact footprint to reduce construction impact and limit environmental impact. 

More Connectivity and Travel Options: Seamless connections to Metro’s D, E, and G Lines, plus Amtrak and Metrolink, will offer passengers easy transfers to existing public transportation. 

Built for the Future: Alternatives 4 & 5 will deploy state-of-the-art technology, including driverless trains that will enhance safety, efficiency, and operational flexibility. 

• STCP brings decades of collective experience building and operating some of the most innovative rail systems around the globe — from the U.S., London, Paris to Western Sydney and Riyadh.

The entire end-to-end journey is completed in just 20 minutes. Trains will arrive at each platform as frequently as every 90 seconds to 2.5 minutes at peak operations. Travel times to know:

• Valley to Westside – 20 minutes
• Van Nuys to Expo Line – 20 minutes
• Westwood Blvd. to Ventura Blvd. – 6.5 minutes
• Wilshire/Westwood to Santa Monica Blvd – under 1.5 minutes

Alternatives 4 & 5 both propose a total of 8 stations, strategically located in high-demand areas to maximize ridership and convenience. Learn more about each station here. Alternative 5 includes 8 stations, 7 of which are underground, while Alternative 4 also features 8 stations, with 4 underground. 

The UCLA station is a key stop, expected to be Metro’s busiest non-transfer station. It will serve students from across the Valley, as well as thousands of employees and visitors to UCLA’s medical facility, one of the region’s largest business hubs. 

All stations are designed with a compact footprint to reduce short-term disruptions from construction and environmental impact.

Seamless connections to Metro’s D, E, and G Lines, plus Amtrak and Metrolink, will offer passengers easy transfers to existing public transportation. We’re committed to getting you where you need to go — safely, efficiently, and on time. From expanding transit in Van Nuys to improving access along Sepulveda and connecting Angelenos to jobs, schools, and entertainment, we’re building a more accessible LA.

Both Alternatives 4 & 5 feature a single-bore tunnel that extends from the Westside through the Santa Monica Mountains. The tunnel will carry trains in both directions. For Alternative 5, the tunnel continues under Sepulveda Blvd., while Alternative 4 transitions to an aboveground structure south of the Ventura station. 

The tunnel design and construction minimize aboveground disruption. An innovative ventilation system controls airflow inside the tunnel, removing the need for intermediate ventilation structures at the surface of the Santa Monica Mountains segment. This system also provides increased safety in the event of an emergency.

Single-bore tunnels are used in several metro systems worldwide, including the Paris Metro (Line 14), Tokyo Metro (Hibiya Line), and others. 

Alternatives 4 & 5 will be deep enough underground that you will not feel or hear the trains. STCP brings proven expertise in tunneling and underground rail, including the recently completed Regional Connector (adjacent to the Disney Concert Hall) and the D (Purple) Line beneath Wilshire Blvd. STCP’s experience also includes the Elizabeth Line in London, which spans 40 miles of track beneath the city’s core.

Metro trains currently operate beneath a wide range of structures — single-family and multi-family homes, commercial and retail buildings, parks, schools, performance venues, and religious institutions — without generating noise or vibration complaints. Metro’s tunnels run adjacent to hospitals and commercial recording studios, both with highly sensitive equipment, which continue to operate without disruption. Additionally, property owners have successfully built projects above Metro tunnels and stations.

STCP is committed to building responsibly and sustainably, using technology that minimizes our carbon footprint. With favorable ridership numbers and efficiency, the rail line will reduce air pollution by encouraging people to choose public transit over driving. All 8 stations are also designed with a compact footprint to reduce environmental impact.

Yes, some housing will be affected during construction. However, STCP is committed to minimizing impacts by working closely with the community and Metro’s Real Estate Department to explore solutions. Our goal is to build this project while being as considerate as possible to residents and businesses.

Platform Screen Doors: Designed to prevent track intrusions and accidents, enhancing station safety.

Secure Access: Ticket-controlled entry, with staff patrols and surveillance ensuring a safe environment.

24/7 Monitoring: A dedicated control center oversees operations, and underground stations are secured at night to prevent unauthorized access.

Yes, the project is anticipated to create thousands of new jobs. We’ve already partnered with 27 local businesses from across the area, each bringing specialized expertise and a commitment to the craft. These local businesses are central to the success of this project, contributing local talent and knowledge that are key to its execution. As the project progresses, we aim to grow this network even further, ensuring that the diversity and professionalism we bring continue to reflect the communities we are working alongside.

LA Metro is considering a public-private partnership (P3) delivery model, which can handle large, complex projects like this one. The P3 model brings together private-sector investment and public funding which can help accelerate the project’s delivery.

A P3 is a partnership between a public agency (such as LA Metro) and a private entity (such as STCP) to deliver a capital project that can be partially financed by private investment. This approach can speed up construction by unlocking private investment early. 

Certainty: The model brings greater cost and schedule certainty, while starting earlier helps avoid rising construction and labor costs.

Acceleration: P3s allow construction to begin earlier than traditional models by tapping into private financing up front. That means the public could see benefits — like reduced congestion and improved transit — sooner.

Accountability: P3 developer responsible not just for delivering the project on time and on budget, but also for maintaining it over the long term. With capital at risk and performance tied to payment, the P3 model holds the private partner accountable from construction through operations.

Innovation: STCP partners bring more than a century of global infrastructure experience — and with it, innovative solutions. For example, fully automated trains can improve reliability, efficiency, and the rider experience while helping to future-proof the system.

Risk Transfer: The P3 model can transfer some of the risk of project delivery to the private partner. STCP only gets repaid after meeting key milestones and once the system is operational — creating incentives to deliver quality, on time and within budget.

The P3 approach can help ensure cost predictability over the life of the project. With the P3 model, capital and operating costs are locked in for the full contract term (typically 30years). This lifecycle approach focuses on long-term value and is intended to reduce the overall cost of ownership.

Yes. The P3 model allows us to partner with local contractors throughout the project’s footprint. The project will offer opportunities for small, medium, and large businesses, boosting the local economy.  STCP is committed to supporting local and disadvantaged contractors, with a focus on giving back to the communities along the entire alignment, from the Valley to the West Side. Given the size and scale of this project, STCP is committed to being a long-term partner in the community, investing not only during construction but for the duration of the P3 contract.

Yes, STCP team members have a proven track record globally, in the U.S., and in California. We’ve delivered successful P3 projects that save on costs, drive innovation, and provide long-term value, and we’ll leverage the best practices from past projects to ensure success and minimize risks.

Here are a few examples of STCP partner’s experience with P3 projects: Presidio Parkway, Long Beach Courthouse, and Fresno State University in California; John F. Kennedy Airport Terminal 6 and LaGuardia Airport Terminal B in New York; the Port of Miami Tunnel in Florida; the Sud Europe Atlantique and Nîmes–Montpellier high-speed rail lines in France; the London Underground in the United Kingdom; and the Waterloo Light Rail Transit in Canada.

P3s have been a part of building U.S. transportation infrastructure since the nation’s founding. Turnpike roads, steamboat lines, the nation’s first railroad, and, more recently, over 15 toll roads and the bulk of the nation's electrical grid have all been financed through P3s.

In their current form, P3s have been used in the U.S. since the early 2000s, leveraging private sector innovation and expertise to fund and deliver road, passenger rail, and airport projects. In California, specifically the Los Angeles area, notable P3 projects include the Consolidated Rent-A-Car and Automated People Mover at LAX, Long Beach Courthouse and the Long Beach Civic Center.

No, Metro will always retain ownership of the Sepulveda Transit Corridor and can enforce penalties and/or terminate the P3 agreement if the P3 developer does not meet its performance-based obligations.

Metro is managing several large-scale projects to improve mobility across Los Angeles, and a P3 approach could allow it to tap into private expertise, innovation, and financing for the Sepulveda Transit Corridor. This could accelerate project delivery while preserving taxpayer dollars for other initiatives.
