This site was created and is maintained by Richard Lent. I am a former conductor previously qualified on CN, CSX, GCOR, NORAC, and NS rules. While actively working I created a website for SMART-TD Local 168 (and shared with the BLET) which featured signal practice along with other union related material. Utilizing the ProProfs platform for quiz delivery, over 25,000 practice exams have been taken by conductors, engineers, managers, and others.
The streamlined Signalquiz.com was launched in 2021 as a way to continue providing signal practice exams to my brothers and sisters nationwide.
Last trip at Amtrak. That's me on the left with Alfred Roy and Steve Wilson!

CORA West Chicago Wye Signals
Should be no three headed combinations on the Amtrak test because of physical characteristics of the Wye. Also no Approach Limited, Advance Approach, or Diverging Approach Diverging. AM & AR are the only two SPEED SIGNALS, the rest are ROUTE SIGNALS (Diverging)
Y, Y/R is Approach. Pretty much the same as NS, but also Y/D, and D/Y
Y/L, and also Y/Flashing R are both Approach Restricting (They both have the restricting characteristic under the yellow. Also, it's just these two combinations for A/R)
Approach Medium (AM radio tower, Top 40 - from an old head in the yard) is: Anything Yellow flashing on top and also solid Y/Y
R/Y is Diverging Approach
R/Flashing Y is Diverging Approach Medium (a little tricky)
Restricting: Anything flashing Red except for Y/Flashing Red (which is Approach Restricting)
Restricting: Anything with a Lunar except for Y/Lunar (which is Approach Restricting)
Restricting: Anything solid Red or Red/Dark combination with a number plate or G marker
STOP: Name for Stop is STOP: Anything all solid Red or Red/Dark combo (w/out a number plate).
STOP: R/D with the semaphore looks like it could be a Restricting. Easy to get wrong.
All indications start with "Proceed".
Approach and Diverging Approach: Trains exceeding 30 MPH immediately reduce. Note: Speed is 40 MPH for passenger trains.
If name starts with Approach indication starts with Proceed prepared to pass or Proceed prepared to stop.
If name starts with Diverging indication starts with Proceed on diverging.
Diverging Approach Medium only one that's 35 MPH. DAM!
Clear is 'Proceed', all POD are 'not exceeding', AM is 'at prescribed speed'
Clear: KISS Proceed
Approach Medium: ** PPP *********** Proceed prepared to pass... not exceeding  Top 40 enter diverging at prescribed
Approach Restricting:** PPP ********* Proceed prepared to pass...
Approach: ** PPS ***************** Proceed prepared to stop [30/40]
Diverging Clear: ** POD ************ Proceed on diverging route not exceeding...
Diverging Approach Medium: ** POD ** Proceed on diverging route not exceeding... [35/40]
Diverging Approach: ** POD ******** Proceed on diverging route not exceeding... [30/40]
Restricting: ** KISS *************** Proceed at restricted speed.
Stop: ** KISS ******************* Stop
KISS = Keep it simple stupid, PPP = Proceed Prepared Pass, PPS = Proceed Prepared Stop, POD = Proceed On Diverging
Note: 'not exceeding' on the Diverging signals is more restrictive than Chi Sub which is 'at prescribed speed', except for Chi Sub Clear, which is 'not exceeding'.
Approach Medium is 'not exceeding', then 'at prescribed speed'.

CSX Standard Signals (Rules 1281 – 1298)
SPEED SIGNALS: Slow, Medium, and Limited – Nothing Diverging
Middle aspect – Anything other than red, Medium somewhere in the name (unless it's flashing, then it's Limited) Bottom aspect – Anything other than red, Slow somewhere in the name (unless it's flashing, then it's Medium)
Flashing bumps up one level. From Slow to Medium or from Medium to Limited. Disregard any lower red lights (high stands and dwarfs), they only demonstrate that the light is working
Restricting(s) all have a lunar in them R/Y high stand is Medium Approach R/R/Y is Slow Approach. All red with a G marker is Grade All red with number plate or P is Restricted Proceed Y/Y is Advance Approach R/Y/Y Medium Advance Approach (same as CN) More or less the dwarfs follow the same convention.
Read the lights on two headed dwarfs as if they were high stand signals. Y/Y dwarf Medium Advance Approach is an exception (it's not an Advance Approach). No dwarf (color light) for Approach
Read single head dwarfs like this: Y is Slow Approach G is Slow Clear (same as NS)
Disregard bottom reds on dwarfs just like high stand signals: Y/R is Slow Approach (same as NS) G/R is Slow Clear (same as NS)
Slow, Medium, and Limited in indications (No MPH). Just like NS. Clear: Proceed. Everything else either proceed or 'not exceeding' except Restricting which is 'at'.
TCS OPP (applies to any signal that starts with a speed first in the name – Slow, Medium, or Limited) Also, when speed is the first word in the name, it is also the first word in the indication. [ XXX Speed] ... through turnouts, crossovers, sidings, and over power-operated switches then proceed
TCS OPP applies to the nine signals below:
Limited Clear: Limited Speed ... then proceed Limited Approach: Limited Speed ... prepared to stop next signal Medium Clear: Medium Speed ... then proceed Medium Approach Medium: Medium Speed ... then Medium Medium Approach Slow: Medium Speed ... then Slow Medium Advance Approach: Medium Speed ... prepared to stop second signal Medium Approach: Medium Speed ... prepared to stop next signal Slow Clear: Slow Speed ... then proceed Slow Approach: Slow Speed ... prepared to stop next signal
Approach: ... exceeding Medium Speed immediately begin reduction ... as soon as locomotive passes.
Restricting: Proceed at Restricted Speed. Restricted Proceed: Proceed at Restricted Speed Grade: Proceed at Restricted Speed
Approach Slow: Proceed, approaching next signal not exceeding Slow Speed. Approach Medium: Proceed, approaching next signal not exceeding Medium Speed. Approach Limited: Proceed, approaching next signal not exceeding Limited Speed.

Collapsible categories are best used when you only have limited signal categories that you are interested in. The collapse function allows you to hide all the categories you don't need. Whatever state you leave the categories in is the state you will find them on your next visit. To use this feature look for the Register link and create an account.
