Metro North In-Cab Signalling

I noticed a large number of hits from the railsimulator.com beta test discussion form on my blog article on cab signal displays a few months ago.

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.

regarding the M8 cab signal display- is there any use associated with the number displays to the immediate right of the RMLN indications?

I think they are 45 60 and 80 or similliar..

They're just numerical speed values used in conjunction with the Normal Cab, Medium Cab, etc. values

Those numerical aspects are not used on MNR territory. Not 100% sure if they're used when the M8s are on SLE.
