Yellow over Flashing Green signal call out

On this post I'll be showing the Y/*G* aspect and what it means on the Class 1's.

Y/*G*, Y/*G*/R CN & CP (Canada Lines) : Clear to Limited - Proceed, approaching next signal at LIMITED speed.

Y/*G*, Y/*G*/R CSX : APPROACH LIMITED : Proceed, approaching next signal not exceeding Limited speed.

Y/*G*, Y/*G*/R CSX: CR Lines : APPROACH LIMITED : Proceed approaching the next signal at Limited speed.

Y/*G*, Y/*G*/R Norfolk Southern: CR Lines : APPROACH LIMITED : Proceed approaching the next signal at Limited speed.

Y/*G*, Y/*G*/R NORAC : APPROACH LIMITED : Proceed approaching the next signal at Limited speed.

Y/*G* BNSF : APPROACH LIMITED : Proceed prepared to pass next signal not exceeding 60 MPH and be prepared to enter diverging route at prescribed speed.

Y/*G*, Y/*G*/R Union Pacific : APPROACH CLEAR SIXTY : Proceed. Freight trains exceeding 60 MPH must immediately reduce to 60 MPH.  Passenger trains may proceed, but must be prepared to pass the next signal not exceeding 60 MPH.  When signal governs the approach to a control point with a 60 MPH turnout speed be prepared to advance on diverging route.

Yellow over Yellow signal call out

On this post I'll be showing the Y/Y aspect and what it means on the Class 1's.

Ex-Southern Line Yellow over Yellow.

Y/Y,Y/Y/R BNSF: APPROACH MEDIUM - Proceed prepared to pass next signal not exceeding 40 MPH and be prepared to enter diverging route at prescribed speed. (Note: This must be an older display for routes that don't have a flashing mechanism.) 

Y/Y,Y/*Y*,Y/Y/R CROR: CLEAR TO SLOW - Proceed, approaching next signal at  SLOW speed.

Y/Y,Y/Y/R CSX: ADVANCE APPROACH - Proceed, prepared to stop at second signal. (Note: No dwarf aspect for it.)

Y/Y,Y/Y/R CSX (Conrail Line's): APPROACH SLOW - Proceed approaching the next signal at Slow speed. Trains exceeding Medium speed must begin reduction to Medium speed as soon as the locomotive passes the Approach Slow signal.

Y/Y,Y/Y/R Norfolk Southern (Southern Line's): ADVANCE APPROACH - Proceed, prepared to stop at second signal.

Y/Y,Y/Y/R Norfolk Southern (Norfolk & Western Line's): ADVANCE APPROACH - Proceed, prepared to stop at second signal.

Y/Y,Y/Y/R Norfolk Southern (Conrail Line's): APPROACH SLOW - Proceed approaching the next signal at Slow speed. Trains exceeding Medium speed must at once reduce to that speed.

Y/Y,Y/Y/R NORAC: APPROACH SLOW - Proceed approaching the next signal at Slow Speed. Trains exceeding Medium Speed must begin reduction to Medium Speed as soon as the engine passes the Approach Slow signal.

Y/Y,Y/Y/R Union Pacific: APPROACH DIVERGING - Proceed prepared to advance on diverging route at next signal at prescribed speed through turnout.
