Colorado Advances $4.7B Front Range Rail Plan, Starter Line Set for 2029
Coloradoโs Front Range Passenger Rail District moved forward on July 21 with a phased delivery plan for a roughly $4.7 billion intercity rail network, starting with a $332 million starter line between Denver and Fort Collins, Engineering News-Record reports.
The districtโs Executive Committee voted unanimously to send Resolution 2026-26 to the full FRPR board, which is set to consider approval on July 31.
Market Impact
The full buildout, known as the Colorado Connector or โCoCo,โ would eventually span roughly 190 miles from Fort Collins to Pueblo through a phased approach spanning about 20 years. The first phase would launch in 2029 with three daily round trips over a 72-mile segment between Denver Union Station and Fort Collins, financed through existing commitments from the Colorado Transportation Investment Office and RTD, with Amtrak as initial operator. The district says this phase requires no new taxes or additional federal funding.
A second phase, estimated at approximately $1.7 billion, would extend service about 75 miles south to Colorado Springs and another 44 miles to Pueblo within five years of securing dedicated funding. That funding hinges on voter approval of a proposed regional sales tax that could appear on the November ballot. The district is preparing a detailed financing plan for committee review in August, and the board may vote on ballot language at its Aug. 28 meeting in Pueblo.
Rather than building new track, the project relies primarily on existing freight corridors, with construction focused on new and extended passing sidings, track and roadbed upgrades, crossovers, signal and communications improvements, stations and maintenance facilities. North of Denver, trains would run over RTD infrastructure before joining BNSF Railwayโs Front Range Subdivision, with later phases extending over the BNSF-Union Pacific Joint Line and Consolidated Main Line. Surface Transportation Infrastructure Development Committee Chair John Putnam said the plan is โbacked up by really solid technical information.โ
What It Means for Subcontractors
- Track and civil contractors should prepare for procurement tied to the 72-mile Denver-to-Fort Collins segment, targeted for 2029 service launch and funded without new taxes, meaning work could move forward regardless of the November sales tax vote.
- Signal, communications, and E&I subcontractors should note the projectโs emphasis on crossovers and signal upgrades rather than new track construction, a scope that favors firms experienced in brownfield rail retrofits over greenfield installation.
- Firms with BNSF and Union Pacific corridor experience should position early, since the second phase (about $1.7 billion) covering Colorado Springs and Pueblo depends on a regional sales tax measure that could reach voters this November, with ballot language possibly finalized Aug. 28 in Pueblo.
- Contractors bidding on stations and maintenance facilities should watch the August committee review of the detailed financing plan, which will shape procurement timing for the second phase.
- Companies with freight-passenger coexistence experience should track the 25-year BNSF access agreement term sheet, since preserving railroad maintenance windows while adding passenger service will require specialized scheduling and construction sequencing expertise.
