The Northwest Rail Project is one component of the larger RTD FasTracks Program that identified, planned, and passed a new tax to build future rail connections in the Denver Metro Region. The Northwest Rail Line (B Line) is one of the outstanding projects identified and will eventually connect Denver Union Station to Longmont. It follows the Burlington Northern-Santa Fe rail corridor, roughly parallel to US 36 to Boulder, then SH 119 to Longmont. Today, the project only provides rail service from Denver to Westminster, but full build-out will result in the service passing through Broomfield with stations at Broomfield Station (approximately W 116th Ave, east of US 36), and Flatiron Station.
