Quiet Zones
RTD instituted quiet zones when the N Line opened for service on September 21, 2020. It is important to note that quiet zones aren’t always quiet. Train operators maintain the discretion to use train horns under circumstances requiring additional safety precautions. If there are questions or concerns about train horn usage, residents may contact RTD Customer Care at 303-299-6000.
Connecting Downtown to Thornton and Beyond
The N Line adds even more commuter rail service to connect the metro Denver region. The first 13 miles of the proposed 18.5-mile line provides service from Union Station through Denver, Commerce City, Northglenn, Thornton, and eventually North Adams County. The remaining 5.5 miles will provide service to SH 7/162nd Avenue Station.
At Union Station, passengers can connect to the E and W light rail lines, the A Line to the airport, the B Line to Westminster, the G Line to Arvada/Wheat Ridge, Local and Regional buses, the Free MallRide, and Free MetroRide.

Rail Fare Zone Map
The RTD rail system is divided into four fare zones: A, B, C, and Airport. Rail fares are based on how many fare zones you travel in during your 3-hour trip. Travel in one or two zones is a Local fare, travel in three zones is a Regional fare, and any trip originating or ending in the Airport zone is an Airport fare.
Stations
The N Line is proposed to have nine stations total, including Union Station, when the entire line is complete. The first phase of 13 miles includes seven stations, and runs from downtown’s Union Station to Eastlake•124th. It offers five new Park-n-Rides that add a total of 2,480 parking spots. The remaining 5.5 miles of track, which includes stations at York•144th and North Thornton•Hwy 7 is currently unfunded. Construction will begin in the future as funding becomes available.
