Northwest Rail Line at a glance
- The Northwest Rail Line is part of RTD’s 2004 voter-approved FasTracks plan to expand transit across the Denver metro region.
- The proposed 41-mile diesel commuter rail corridor would operate between Denver’s Union Station and Longmont, passing through north Denver, Adams County, Westminster, Broomfield, Louisville, Boulder and Boulder County.
- The line's seven proposed stations are: Westminster (completed July 25, 2016), Church Ranch, Flatiron, Louisville, Boulder Transit Village, Gunbarrel and downtown Longmont.
- 2010: RTD FasTracks Environmental Evaluation was completed, identifying the benefits and effects of implementing transit on BNSF Railway right-of-way.
- 2012: Construction of the first 6.2-mile electrified segment between Union and Westminster stations began as part of the Eagle P3 project set to open in 2016; it will operate as the B Line upon completion.
- 2013-2014: RTD FasTracks and its contractor completed the 15-month-long Northwest Area Mobility Study to determine the best mobility options for northwest communities including, the feasibility of building the Northwest Rail in phases and providing arterial bus rapid transit.
- 2015-2016: RTD FasTracks earmarked $17 million to build the first phase of the end-of-line station in Longmont under a construction-ready plan; RTD will use the station for bus transfers then upgrade to a rail/bus facility after it completes the Northwest Rail. Construction of the station will begin in 2015 and end in 2016.
