Flaggers positioned at crossings along the University of Colorado A-Line for two years — at a cost estimated in the tens of millions of dollars.

“This is never going to end”: A-Line flaggers return, signaling more delays... Barely a month after the last of the flaggers was taken off duty along the University of Colorado A-Line, some are once again directing traffic at several crossings after a “safety critical software problem” was discovered along three passenger rail lines in the metro area.

The big question, to which there is no immediate answer: How long will the latest challenge in rolling out the Regional Transportation District’s $2.2 billion commuter rail system last? And what does it mean for the long-awaited opening of the G-Line to Wheat Ridge and Arvada and the quelling of train horns that have rattled nerves for more than two years?

The G-Line was originally set to begin carrying passengers in the autumn of 2016. But the line has been delayed by gate timing issues on the A-Line, which uses the same gate crossing technology.

Funny how automatic crossing gates are still working everywhere else in the country. Is it that much harder to have put those in and to have the train operators sound the traditional grade crossing horn signal?

Colorado Ping ( Let me know if you wish to be added or removed from the list.)

RTD = Reason to Drive ( Loud train horns, too. )

Golly gee, what did they do before computers?

The issue is using new technology (GPS, wireless, PTC [positive train control]) mandated by Congress after the Chatsworth CA head-on collision in 2008 that killed 25 (the gay engineer was texting with young boys and ran a red signal). Unfortunately the new technology is still in the testing phase and software problems along with some hardware issues have caused problems. Quiet zones with no horns sounding are quite common using old technology, but the inclusion of PTC in the mix caused system failures.

I bet that rail system made some politicians and their friends extremely rich.

I see that it is a software issue. .

I think they should hire the people who designed the Obamacare website. I hear they’re not terribly busy these days

Give it to me and I’ll have them working like clockwork at half the price.
