However this is part of a new setup Amtrak is having for its cab signals. I do not know if Amtrak is going to use this to supplement their own signals or not. See this picture, it's not just the ACS-64 that has this setup... http://www.rrpicturearchives.net/showPi ... id=3689784
In the picture on the ADU, what does VZ mean?

SLickFlair, welcome to Railroad.net. I did a little pruning to your quote on your posting, just to grab the pertaining portion.

As far as VZ light, it stands for Velocity Zero, and illuminates when the electronics detect that the engine/consist is no longer in motion.
