Riverside Metro Regional Connections: Linking to LA Metro, Metrolink, and Other Systems

Riverside Metro operates within a broader network of Southern California transit systems, and understanding how these systems interconnect is essential for riders traveling beyond Riverside County boundaries. This page covers the definition and scope of regional transit connections, the mechanisms that make multi-agency travel function, common transfer scenarios riders encounter, and the decision boundaries that determine which system or service is most appropriate for a given trip. Riders who need a broader orientation to Riverside Metro's offerings can begin at the Riverside Metro home.

Definition and scope

Regional connections in public transit refer to formally coordinated or physically co-located points where two or more separate transit agencies allow riders to transfer between their respective networks. In Southern California, Riverside Metro's regional connections are defined primarily by three partner agencies: LA Metro, which operates the bus and rail network for Los Angeles County; Metrolink, the Southern California Regional Rail Authority serving six counties including Riverside and Los Angeles; and Omnitrans, the transit agency covering the San Bernardino Valley.

These connections are not informal arrangements. Metrolink operates under a Joint Powers Authority structure established by the founding member agencies — including the Riverside County Transportation Commission (RCTC) — which means service coordination, fare reciprocity discussions, and station infrastructure responsibilities are governed by binding interagency agreements. The Southern California Association of Governments (SCAG), the federally designated Metropolitan Planning Organization for the six-county region, coordinates the long-range transportation planning framework within which all these agencies operate.

The geographic scope of Riverside Metro's regional connections extends across four primary corridors:

1. West to Los Angeles County — via Metrolink's Riverside Line and San Bernardino Line, which terminate at Los Angeles Union Station (LAUS)
2. Northwest to the San Gabriel Valley — via Metrolink stations at Pomona, Covina, and connecting LA Metro Gold/A Line stations
3. Southwest to Orange County — via Metrolink's Inland Empire–Orange County (IEOC) Line, which links Riverside to Anaheim and Santa Ana without requiring a transfer through Los Angeles
4. East into San Bernardino County — via Omnitrans Route sbX and local connecting bus routes

For riders consulting Riverside Metro routes and lines, the routes most directly tied to regional connections are those terminating at or near Riverside–Downtown Station, La Sierra Station, and Pedley Station — all of which serve as Metrolink boarding points.

How it works

Regional transfers function through a combination of physical infrastructure, schedule coordination, and fare policy.

Physical infrastructure: Metrolink stations within Riverside County — including Riverside–Downtown, Riverside–La Sierra, Riverside–Hunter Park/UCR, and Pedley — serve as the primary multi-agency nodes. At these stations, Riverside Metro local and bus rapid transit routes are timed to meet Metrolink arrivals and departures where operationally feasible. Park-and-ride facilities at these stations, described in detail on the Riverside Metro park-and-ride page, are critical to how regional commuters access the intermodal network.

Schedule coordination: Metrolink publishes its timetables through Metrolink's official schedule portal. Riverside Metro publishes connecting bus departure times through the Riverside Metro schedules resource. These two systems are not locked into mandatory timed transfers, which means schedule gaps can occur — particularly on off-peak or weekend service windows.

Fare policy: Riverside Metro and Metrolink maintain separate fare structures. A rider boarding a Riverside Metro local bus and then a Metrolink train pays two distinct fares under two separate systems. The TAP card functions as the fare payment medium for LA Metro and many connecting operators, but Metrolink uses a separate ticketing platform accessible at station vending machines and through the Metrolink app. Riders comparing fare options should consult the Riverside Metro fares and passes page for the Riverside Metro portion of any trip.

Common scenarios

Scenario A — Riverside to Downtown Los Angeles (commuter): A rider boards a Riverside Metro local bus at a neighborhood stop, transfers at Riverside–Downtown Station to a Metrolink Riverside Line train, and arrives at Los Angeles Union Station approximately 75 minutes later (schedule-dependent). At LAUS, LA Metro's A Line (Blue), B Line (Red), and J Line (Silver) provide onward connections throughout Los Angeles County.

Scenario B — Riverside to Anaheim (Inland Empire–Orange County corridor): The Metrolink IEOC Line provides a direct rail connection between Riverside–Downtown and the Anaheim Regional Transportation Intermodal Center (ARTIC), eliminating the need to route through Los Angeles. ARTIC connects to OCTA bus routes and Amtrak Pacific Surfliner service.

Scenario C — Cross-county local bus connection (San Bernardino): Riders traveling between Riverside County and San Bernardino County for shorter distances may use Omnitrans services. The Omnitrans Route sbX Bus Rapid Transit corridor runs between San Bernardino and Loma Linda, and connecting Riverside Metro routes at the county boundary facilitate this transfer without rail.

Scenario D — First/last mile from a Metrolink station: Riders arriving by Metrolink at La Sierra Station who need to reach points within western Riverside use Riverside Metro connecting routes. Details on this trip pattern are covered on the Riverside Metro first and last mile solutions page.

Decision boundaries

Choosing between driving, Metrolink, or Riverside Metro local service depends on three primary variables: trip distance, time sensitivity, and transfer tolerance.

Riders with accessibility service needs should note that Metrolink and LA Metro both maintain ADA-compliant station infrastructure, but the specific lift, ramp, and boarding assist procedures differ by agency. Confirming accessibility equipment availability at transfer stations before travel is advisable for mobility device users.

For trips where real-time schedule confirmation is critical — particularly when Metrolink delays could affect a timed Riverside Metro connection — the Riverside Metro real-time arrivals tool and Metrolink's real-time train status page serve as complementary resources. Service disruptions affecting regional connections are published through Riverside Metro service alerts.
