DENVER, Colo. — Denver Regional Transportation District’s G-line, a new route intended to link the western suburb of Wheat Ridge to central Denver, still does not have a firm opening date.

The G-Line’s opening last fall was delayed by software issues on the A-Line, which links Denver International Airport to downtown Denver. RTD says that the system employed on the two lines is the first in the country to attempt to combine positive train control and a wireless signal system. However, software glitches have caused the grade-crossing gates to come down too early and stay down too long after the train passes. Last April, the FRA granted a waiver to use  round-the-clock flaggers at affected grade crossings.  

The Denver Post  reports that since the G-Line uses the same grade crossing technology,  the FRA won’t grant a waiver to flag the crossings along that route until it is satisfied that progress resolving the A-Line’s software issues is underway.

The G-Line is projected to have close to 13,000 daily boardings at seven stations and was constructed as part of a $2.2 billion dollar packet that also provided for the construction of the A and B-lines.

RTD does not have an estimate as to when the software issues will be resolved, but is set to seek an extension when the A-Line waiver expires on Feb. 4.
