Completing the B Line to Boulder, Longmont and beyond…

Peak Service Study

Over a period of approximately 24 months, the Northwest Rail Peak Service Study will identify the requirements, costs, and operational needs to upgrade existing track, develop rail stations, and provide peak service to northwestern metropolitan communities, which include Arvada, Westminster, Broomfield, Louisville, Boulder and Longmont.

The first section of the Northwest Rail, known as the B Line, currently operates between Denver Union Station and Westminster Station at 72nd Avenue. Findings and implementation recommendations from the Study will help RTD and partners determine the feasibility of extending rail service through an initial peak service approach. The continuation of the Northwest Rail to Longmont offers opportunities for possible partnership with agencies like the Front Range Passenger Rail District.
