Question about signal lights on the 7 and trip arms

Posted by JRR4 on Sun Apr 14 15:22:52 2019

I have only seen videos of the signal lights (green blinking mostly) since the 7 was upgraded. What do the signal lights mean now? Also, how does a trip arm know when a train has completely passed so it can pop back up? Thanks!
