Why doesn’t RTD use age-old technology at rail crossings?
“G-Line launch might not come until 2018,” June 30 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.
