RTD, DTP to increase number of trains being tested on G Line

Beginning Friday, August 3rd, testing on the forthcoming G Line to Arvada, Wheat Ridge and Adams County will add another notable step forward with the addition of more trains on the alignment up to 24-hours a day.

Limited testing along the forthcoming 11.2-mile line between Union Station and Wheat Ridge began last fall and, until July 20th, had been underway between 8 a.m. and 6 p.m. on weekdays since the start of this year. Starting July 20th, up to six trains have been tested every day starting as early as 3:30 a.m. and extending through 1 a.m. the following day. The testing process has examined the communication signaling along the G Line, as well as the effectiveness of the communication technology in place at each of its 16 at-grade railroad crossings. The gate-crossing technology in place along the G Line is the same as that used on the University of Colorado A Line, to Denver International Airport, and the B Line, to Westminster.

“We are excited to see G Line testing ramping up,” said RTD CEO and General Manager Dave Genova. “Safety remains crucial during this time, and while we know that people are as excited as we are to see many trains on the alignment, we ask that they keep an appropriate distance and respect the work taking place on their behalf.”

The public should abide by all safety signage, heed potential closures of railroad or at-grade crossings, and not attempt to view the work by accessing construction areas at stations and various locations along the tracks.  

During testing, train operators will continue to sound their horns when passing through intersections. Until quiet zones have been approved by the FRA, the use of train horns and other safety measures are important to make drivers and pedestrians aware of train movements. RTD will announce the start of quiet zones for the G Line once such approvals from the FRA have been secured.

When the G Line officially opens, trains will run from 4 a.m. to 12:30 a.m., with 15-minute frequency between 6 a.m. and 6:30 p.m. and every 30 minutes during off-peak hours.

Crossing gates may stay down for extended periods of time during testing. Attendants will continue to be stationed at all G Line grade crossings until RTD receives the necessary state and federal approvals to remove them.

In case of an emergency, the public can call 720-460-5955, the grade-crossing hotline, or 303-299-3911 after hours.

The G Line is a segment of RTD’s FasTracks program, a voter-approved transit expansion initiative to build new commuter rail and light rail, bus rapid transit service and new parking spaces; redevelop Denver Union Station; and redirect bus service to better connect the eight-county district.
