After more than a year of trying to address problems at crossing gates along RTD's A, B, and G commuter-rail lines, the systems that control the timing of the gates are the best they can be, even though that may not satisfy federal and state regulators, the contractor operating the trains has told the transit agency. And with Denver Transit Partners (DTP) saying there is no improvement in sight, or even possible "with available technology," the contractor told the Regional Transportation District in a May 26 letter to quit levying fines against it for problems beyond the contractor’s control. http://www.9news.com/money/business/disagreement-emerges-between-rtd-contractor-over-rail-line-problems/446631294
I think the problem is that they got entranced with technology that is too complicated. Instead of having sensors in the track that are connected to the crossing arms, they have GPS systems on the trains that go up to satellites, then to a command center, then internet over radio to the crossing arms. I think they should scrap the whole system and do it the old way. Yea it will cost more, but RTD is spending $6 million per year just on extra crossing guards and police protection. This is ridiculous.
