More commuter rail comes to the Denver metro area with the N Line (referred to as the North Metro rail line during construction). The first 13 miles of the proposed 18.5 mile commuter rail line will provide service from Union Station through Denver, Commerce City, Thornton, Northglenn, and eventually to north Adams County.

Service

New Rail in New Neighborhoods

The N Line brings RTD train service through Denver, Commerce City, Northglenn, Thornton and north Adams County. The N Line will connect at Union Station where riders have the option to transfer to the University of Colorado A Line to the airport and other rail lines that depart from Union Station and downtown.

Connections

The N Line will offer convenient train service to connect the northern metro area to the rest of the greater Denver region.

Important Safety Tips

  • Do not try to touch or throw objects at the overhead power lines or climb on the power poles — if the wires are up, they are live with 25,000 volts of electricity!
  • Never trespass on any train track — it is illegal and dangerous.
  • Cross the tracks only at designated crossings, always follow safety signage and obey warning devices like flashing red lights and gate arms.
  • Stay alert and look both ways for a train — you may not hear them coming.
  • Stay off station platforms until they are open to the public.
