G Line Update from RTD
Posted on 02.06.19
The Federal Railroad Administration (FRA) approved revenue service demonstration – a key step in certification of positive train control (PTC) – of the commuter rail line to Wheat Ridge, Arvada and Adams County, as well as adding the G Line to an existing long-term waiver for the University of Colorado A Line and B Line. These represent substantial landmarks in the approval process, which includes several additional steps at both the federal and state levels.
RTD will continue to pursue necessary steps to implement quiet zones along the 11.2-mile line. Crossing attendants also must remain along the G Line as RTD and concessionaire Denver Transit Partners (DTP) work through items outlined in a plan submitted to FRA late last year.
Additional critical steps must be met before we can open the G Line and implement quiet zones:
- DTP continues to optimize and adjust the grade crossing timing. The Public Utilities Commission (PUC) is in the process of conducting field verifications. Once these are completed, then we will undergo the formal PUC approval process.
- FRA will require additional progress reviews to allow removal of the grade crossing attendants and establishment of the quiet zones before public service begins.
Here is where we are with the quiet zone process on the G Line:
The waiver request for constant warning time on the G Line grade crossings in Arvada and Wheat Ridge was submitted to FRA on Nov. 16, posted in the federal register on Dec. 13 and the comment period closed on Jan. 28.
- The waiver request for constant warning time on the G Line grade crossings in Adams County was submitted the week of Dec. 17. It will still need posting to the federal register to open up the 45-day comment period.
After closing of the comment period, the FRA will consider the approval of the waiver(s).
Assuming the waivers for constant warning time are approved, the next step is to file the notice of establishment for quiet zones, followed by a 21-day period, then FRA concurs, quiet zones are established.
RTD stands ready with local jurisdictions to file the notice of establishment as soon as the waivers are approved.
RTD credits the collaborative work with our partners for reaching these milestones. We remain committed to meeting the requirements of our regulators and will continue working closely with them, as well as keeping the public involved at every turn.
Updates will be made available on the RTD website.
