A crossing guard stops traffic as an RTD train travels along the A-Line in Aurora on March 17, 2017. RTD and its private partner struggled to implement the automated crossing system on the A-Line, and similar issues were partly to blame for holding up the opening of the G-Line.Re: June 29 news story.
I’m surprised RTD hasn’t gone back to the tried-and-true mechanism for lowering and raising railroad crossing arms that has been in use since the early 1900s. The solution is to isolate all the crossings from each other and from any computer network, and place sensors in the track before and after the crossing. When the train is coming, a sensor causes the gates to go down; after the train passes, another sensor causes the gates to go up. This is not rocket science.
