Re: Question about signal lights on the 7 and trip arms

Posted by Allan on Sun Apr 14 16:23:34 2019, in response to Question about signal lights on the 7 and trip arms, posted by JRR4 on Sun Apr 14 15:22:52 2019.

Blinking green lights indicate that CBTC is active in that area.

As for the stop arms I would assume that signal relays in some fashion are still in use.
