Thats exactly what I was thinking
I'm guessing you copied that about the signals right out of your rule book. They sure are different from NORAC. We don't have any of those.
The signals I saw on the video,we have. Yellow over yellow is a approach slow(approach the next signal at slow speed). The red over green is a slow clear(proceed thru crossover or spring switches at slow speed until entire train gets thru,then normal speed). This would make sense to me because it's a usual progression to slow you down for the crossover. Mind you each book(rule book region) is different & speeds vary for passenger & freight.For us slow speed=20mph. Because of cab signals,I'm usually around 15,just for trying to run a smooth train & so I don't get hit with a penalty.
When it(signal) dropped to red over red,the other train tripped the circuit. Again,to late to do anything.
Yup, actually SSI. I dont have a set of NORAC cuz we didn't use it but
I have signal aspects and their indications in my C.O.R.A.(Chicago Operating Rules Association)rule book for railroads that use NORAC.
I also have AMTRAK signal aspects and indications and rules as they
apply to the Chicago Terminal. Amtrak owns Chicago Union Station and
trackage ancillary to it. METRA is a tenant of Amtrak at CUS so those
of us on the BNSF who work METRA trains have to be examined on those rules.
We have a line out of Louisville that we use 5 different kinds of signals along with DTC blocks. It is a result of all the CSX mergers.
