RTD service changes take effect today adding rail connections and increasing frequencies
The agency is reinstating the C Line, adding the temporary T Line, and increasing frequencies on the B and G lines to boost mobility options across the region
DENVER (June 7, 2026) –– The Regional Transportation District (RTD)’s service changes took effect today and introduce new connections, increased bus and train frequencies, and improved schedules. Many of the adjustments will support customers during the next phase of the agency’s multi-year Downtown Rail Reconstruction Project starting June 7.
To fortify mobility options and enable customers to keep making connections during the Downtown Rail Reconstruction Project, June’s service changes introduce a temporary T Line along the Southeast Corridor, reinstate the C Line to Denver Union Station, extend the R Line to RidgeGate Parkway Station, and increase train frequencies on the B and G lines.
Customers also will see improved services for 12 bus routes to enhance on-time performance and connections, resulting from $9.25 million funding from a Clean Transit Enterprise (CTE) grant program. The program stipulates that RTD use the funding in 2026 to increase frequencies, expand hours of service, or augment connections. The CTE grant is funded through oil and gas production fees, and it is annually available to transit agencies across the state.
RTD continually monitors its transit system and adjusts its schedule three times a year – typically in January, May or June, and either August or September. The transit system evaluation considers a variety of factors such as traffic patterns, economic conditions, and customer feedback. Ongoing system assessments are imperative for making informed decisions that maximize resources, enhance on-time and reliable services, and ensure that RTD continues to meet the needs of the region it serves.
For a complete look at the updates, RTD encourages customers to use the Next Ride app to plan for any travel adjustments from bus routes and rail lines affected by the service changes. Customers also may visit Service Changes.
