Denver RTD to implement quiet zones on commuter-rail line next month

The Regional Transportation District (RTD) and the city and county of Denver last week received the necessary federal approvals to establish quiet zones at nine grade crossings for the University of Colorado A Line commuter-rail service starting March 1.

The Federal Railroad Administration (FRA) approved RTD's waiver for constant warning time devices at the nine crossings in Denver on what is known as the A Line. In addition, the city and county fielded the notice of establishment for quiet zones, which is the formal process required by the FRA before quiet zones can be implemented.

Combined, the two actions pave the way for the A Line's quiet zones. The actions also represent a milestone for commuter-rail service in the Denver region, RTD and local government officials said in a press release.

"We've been working with RTD to make sure the A Line enhances our residents' quality of life by pushing to limit the noise that may be detrimental to those who live, work or stay near the corridor," said Denver Mayor Michael Hancock. "The A Line is an important connector between homes and jobs, education, recreation and more, providing access to equity for these neighborhoods and the residents who live there."

Train operators will continue to use train horns under certain circumstances that require additional safety precautions, RTD officials said. Gates, lights and bells will continue to activate and sound at crossings.

Meanwhile, the RTD, FRA and city of Aurora continue to work through the process of establishing quiet zones on the two remaining crossings along the University of Colorado A Line located in Aurora.
