B Line commuter rail B Line at a glance ■ The B Line (also known as 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 commuter rail corridor would operate between Denver’s Union Station and Longmont, serving north Denver, Adams County, Westminster, Broomfield, Louisville, Boulder and Boulder County. ■ The line's seven proposed stations are: Westminster, Church Ranch, Flatiron, Louisville, Boulder Junction, Gunbarrel and downtown Longmont. ■ The first segment of the line to Westminster is part of the Eagle P3 project that also includes the University of Colorado A Line and the G Line. Project Overview 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. The remainder of the line will use diesel-powered commuter cars. 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. 2016 The first segment of the line opened to public as the B Line on July 25, 2016. Future RTD FasTracks will begin construction on the line between Westminster and Longmont when funding becomes available.
