Railfanning Detroit! (July 2021)

Amazing video! One question though...why the heck is the signal at 00:20 showing green when there is a moving train coming toward you? I would think both signals should be red in that scenario. That's a little unsettling.

That specific signal does not govern direction of traffic. That signal only governs the diamond with the Conrail Shared Assets track off of Main 2 into the BASF Chemical Company. Therefore if that switch is locked normal that signal will stay green in both directions 24/7. Once that switch is open and unlocked it will then turn red. Also when CN goes past the opposing signal the other will go red but once the last car goes by it'll go back to green as it shows in the video. Hope this helps!
