VERIFIED SOLUTIONS UPDATE |2026!! STUDY GUIDE EXAM/NEWEST UPDATE!!!
Question 1
BNSF 5467 East passes a yellow flag 2 miles in advance of a 20 mph Form A track bulletin
restriction. When is the crew permitted to resume maximum authorized speed?
A) When the leading wheels pass the green flag.
B) When the leading wheels are clear of the restricted area.
C) When the rear of the train is clear of the restricted area.
D) Two miles after the yellow flag.
E) When the dispatcher gives verbal permission.
Correct Answer: C) When the rear of the train is clear of the restricted area.
Rationale: According to GCOR 5.4.2, a yellow flag warns of a speed restriction ahead. The
train must not exceed the restricted speed until the entire train (the rear) has cleared the
specified limits of the restriction.
Question 2
A train passes a yellow-red flag at MP 280, but the crew has no track bulletin or warrant
specifying a restriction at that location. They are unable to contact the employee in charge. How
must the crew proceed?
A) Proceed at maximum authorized speed and look for a red flag.
B) Stop immediately and wait for the dispatcher to call.
C) Proceed at Restricted Speed.
D) Proceed at 10 MPH.
E) Proceed at 30 MPH until a green flag is seen.
Correct Answer: C) Proceed at Restricted Speed.
Rationale: GCOR 5.4.3 states that if a train passes a yellow-red flag without a track bulletin
or contact with the employee in charge, the crew must immediately move at restricted
speed, prepared to stop short of a red flag or men and equipment.
Question 3
In the scenario where a train passed a yellow-red flag without a bulletin, when may the crew
finally resume speed if no red flag is found and no contact is made?
A) After traveling 2 miles.
B) After the leading wheels have traveled 4 miles beyond the yellow-red flag and the dispatcher
verifies no men/equipment are protected there.
C) As soon as the rear of the train passes the next milepost.
D) Only after receiving a new Track Warrant.
E) Immediately after passing the first signal.
Correct Answer: B) After the leading wheels have traveled 4 miles beyond the yellow-red
flag and the dispatcher verifies no men/equipment are protected there.
Rationale: GCOR 5.4.3 requires 4 miles of travel beyond the flag to ensure the train has
, 2
safely cleared any unlisted work zones, provided the dispatcher confirms no known
protection exists at that location.
Question 4
BNSF 5540 West passes a yellow flag but has no track bulletin for a speed restriction. The
dispatcher verifies no bulletin is in effect. What is the speed requirement for the crew once they
are two miles beyond the yellow flag?
A) Proceed at maximum authorized speed.
B) Proceed at a speed not exceeding 10 mph until the rear passes a green flag or is 4 miles
beyond the yellow flag.
C) Stop and wait for a foreman.
D) Proceed at Restricted Speed until the next signal.
E) Proceed at 20 MPH until the next milepost.
Correct Answer: B) Proceed at a speed not exceeding 10 mph until the rear passes a green
flag or is 4 miles beyond the yellow flag.
Rationale: Per GCOR 5.4.2, when a yellow flag is encountered without a matching bulletin,
the crew must treat it as a 10 MPH restriction starting 2 miles after the flag and continuing
for another 2 miles (or until a green flag is found).
Question 5
BNSF 8109 West is stopped clear of the main track in a siding at Julianna to meet two opposing
trains. What is the proper position for the locomotive headlights?
A) On Bright.
B) On Dim.
C) Off.
D) Flashing.
E) Off on the lead unit, Dim on the rear unit.
Correct Answer: C) Off.
Rationale: GCOR 5.9.2 requires that the headlight be turned off when a train is stopped
clear of the main track in a siding to meet other trains, helping the opposing crews better
identify the signal and the turnout.
Question 6
When approaching a public crossing at grade with the engine in the lead at 55 mph, when must
the whistle signal (long, long, short, long) be initiated?
A) Exactly 1 mile before the crossing.
B) At or about the whistle sign, but not more than a quarter mile before the crossing.
C) When the crossing is clearly visible to the engineer.
D) Only if traffic is seen on the roadway.
E) 15 seconds before impact.
Correct Answer: B) At or about the whistle sign, but not more than a quarter mile before the
, 3
crossing.
Rationale: GCOR 6.32.2 dictates the timing of the crossing whistle to ensure motorists are
warned in a consistent timeframe, limiting the signal to a maximum of 1/4 mile prior to the
crossing.
Question 7
Blue signal protection is being established on Yard Track 0703 for a carman. Which of the
following is a mandatory step for proper protection?
A) Simply tell the engineer to set the brakes.
B) Line each manually operated switch against movement to the track and lock it with an
effective locking device.
C) Place a red flag on the locomotive.
D) Position a crew member to watch the switch.
E) Turn off the radio.
Correct Answer: B) Line each manually operated switch against movement to the track and
lock it with an effective locking device.
Rationale: GCOR 5.13 (Blue Signal Protection) requires physical isolation of the track
where workmen are present. This includes lining switches away from the track and locking
them to prevent accidental entry by other equipment.
Question 8
BNSF 4400 West is operating in CTC territory and approaches a controlled signal that is dark
(no lights displayed). What is required?
A) Pass the signal at Restricted Speed.
B) Treat it as a "Clear" signal if the dispatcher says so.
C) Stop and contact the control operator for instructions.
D) Proceed at 10 MPH until the next signal.
E) Replace the light bulbs.
Correct Answer: C) Stop and contact the control operator for instructions.
Rationale: In CTC (Centralized Traffic Control), a dark signal is an improperly displayed
signal. GCOR 9.12.1 and related rules require the train to stop and obtain instructions
from the dispatcher/control operator before proceeding.
Question 9
BNSF 3818 West is in ABS limits and approaches a dark signal that is equipped with a number
plate. How must the crew proceed?
A) Stop and stay until a green light appears.
B) The train may pass the signal at restricted speed without stopping and must report it.
C) Proceed at maximum speed; the number plate means the signal is optional.
D) Stop and contact the dispatcher for a track warrant.
E) Wait 10 minutes, then proceed at 20 MPH.
