My understanding is they’re using new radio-based technology to trigger the gates & flashers for the higher-speed trains and that it’s this technology that is the problem.

I was involved only in the early phases of that project (before it was awarded), but that’s what I understand is going on. There are challenges in trying to implement conventional train detection technology on electrified rail lines.

Thanks. I was wondering about what was going on during the train rides to and from DIA with guards sitting around in their lawn chairs.

Grade separation was also invented some time ago too.
