Regional Express (ReX) Transit Network

The ReX Network can dramatically improve transportation in the Bay Area, connecting regional and local transit networks into a seamless whole. 

ReX would make it easier for millions of residents to get around the region on transit. It is designed to connect the Bay Area’s transit systems, minimize travel times and wait times, and broaden access to regional rapid transit service. The core of the ReX network is intended to run on TransForm’s proposal for a fully connected system of express lanes, building on the network that is already beginning to take shape on the Bay Area’s freeways.

The ReX concept stemmed from a joint Horizon proposal from TransForm and SPUR to the Metropolitan Transportation Commission (MTC) to rethink the future of our highways. It was one of six “Transformative Transportation Projects” chosen by MTC for study and potential inclusion in Plan Bay Area 2050.

How does ReX work? 

The ReX Transit Network is designed to provide the kind of transit service that research shows both current and potential riders want. 

  • Fast travel times - Faster than driving a solo vehicle at peak times.
  • Frequent service - No need to look at a schedule! ReX Express Routes operate every 5 minutes during peak hours and 10 minutes off-peak.
  • Convenient locations - Many ReX stations are integrated with other transit stations (making transfers easy), and are also near jobs, shopping, medical centers, colleges, and more, including destinations not well-served by existing rapid or regional transit. 
  • Clean, safe, attractive facilities - Station design emphasizes protection from the elements and moving vehicles, with Hubs also offering retail and food options.

ReX is designed from the ground up to look and feel like an advanced rail system, with attractive, rail-like stations, fare prepayment (much like on BART), and high-tech vehicles that place passenger comfort and convenience first and foremost. 

ReX does not supplant the Bay Area’s multiple rapid transit and local bus systems. Rather, it complements them, connects them effectively with each other, and builds ridership across all systems. ReX provides high-level connectivity that makes transit a more useful option for many people’s needs.

The current form of the ReX concept is a detailed first draft of the proposal. Much will change before ReX becomes a reality. TransForm is eager to engage stakeholders from transit agencies to transit riders to ensure ReX integrates efficiently with existing services and meets the needs of the people and communities it ought to serve.

ReX alone cannot solve the Bay Area’s complex transportation challenges, but it can help make real progress in a number of important ways. 

  • Efficiency. Make more efficient use of existing highways, moving many more people in fewer vehicles and reducing the perceived need for environmentally damaging highway widening.
  • Environment. Provide a convenient alternative to solo driving for thousands of commuters and residents, reducing greenhouse gas emissions and air pollution. 
  • Equity. Better serve transit-dependent populations and many communities without easy access to existing regional transit.
  • Capacity. Increase transit capacity as the region grows, improving service and benefits for existing riders while also attracting significant new ridership.
  • Overcrowding. Help relieve overcrowding where it exists on regional rail systems, including the Caltrain corridor and BART between San Francisco and the East Bay. 
  • Housing. Create new opportunities for walkable communities with affordable homes near high-quality transit.
  • Savings. Save Bay Area residents time and money by reducing travel times, providing a viable and affordable alternative to solo driving, and reducing auto-dependence. 

Making ReX a Reality

The most exciting part about ReX is that it is within our reach. ReX can be implemented relatively cost-effectively, quickly, and flexibly, with improvements phased in based on demand, feasibility, political will, and other factors. It’s under consideration by MTC for Plan Bay Area 2050,
