BNSF CONDUCTOR FINAL EXAM TEST BANK
QUESTIONS & COMPLETE SOLUTIONS
GRADED A+
This comprehensive study guide is designed to prepare you for the BNSF Conductor Final
Exam. This exam covers advanced railroad operations, signal rules, train handling, safety
protocols, and specific General Code of Operating Rules (GCOR) requirements. The following
100-question test bank contains 100% verified solutions and rationales, updated for the
2026/2027 curriculum.
Instructions: Read each question carefully and select the best answer. Use the provided
rationale to ensure you understand the underlying principle of the question.
1. BNSF 540 East passes a yellow-red flag at MP 280, and the crew has no track bulletin
specifying a restriction. They try unsuccessfully to contact the employee in charge. They
contact the dispatcher, who verifies there is no restriction in effect at that location. Two
miles from the location of the yellow-red flag, the crew does not find a red flag. How
must the crew proceed? When may the crew increase speed?
Answer: The crew must proceed at restricted speed. Increase speed only after a crew
member has received instructions from the employee in charge or the leading wheels have
traveled 4 miles beyond the yellow-red flag and the dispatcher has verified no track
bulletin or track warrant protecting men or equipment is in effect at that location.
Rationale: A yellow-red flag indicates a stop warning. If no red flag is found, the rule
requires proceeding at restricted speed until specific conditions are met (4 miles travel or
direct authorization).
2. BNSF 5540 West passes a yellow flag and has no track bulletin specifying a
temporary speed restriction. They contact the dispatcher, who verifies there is no track
bulletin in effect at that location. What is required of the crew?
,Answer: Once the train is two miles beyond the yellow flag, continue at a speed not
exceeding 10 mph until the rear of train has passed a green flag or is 4 miles beyond the
yellow flag.
Rationale: This is the standard recovery procedure for passing a yellow flag without an
associated bulletin. The train must operate at reduced speed until the end of the restriction
is confirmed by a green flag or the required distance.
3. The crew of BNSF 8109 West has stopped clear of the main track in the siding at
Julianna to meet two trains. What is the proper position for their headlights?
Answer: OFF
Rationale: When stopped clear of the main track to meet oncoming trains, headlights must
be turned off to prevent blinding the approaching crews.
4. When approaching a public crossing at grade with the engine in front at 55 mph, when
should whistle signal ( - o - ) be started?
Answer: Start the signal at or about the crossing sign, but not more than a quarter mile
before the crossing
Rationale: This is the standard timing for whistle signals to provide adequate warning to
motorists without causing excessive noise nuisance further back.
5. On yard track 0703 at the originating terminal, an outbound freight train is made up
and the engine has been placed on the train. Before the initial terminal air brake
inspection and test are made by carman, which of the following would provide proper
blue signal protection?
Answer: Line each manually operated switch against movement to Track 0703; lock each
switch with an effective locking device; and place a blue signal at or near each switch and
on the controlling engine where it is visible to the engineer.
Rationale: This is the standard protection protocol for train servicing and air brake tests to
prevent movement or coupling onto the train.
6. BNSF 4400 West is operating in CTC territory and approaches a controlled signal that
is dark. What is required?
, Answer: The train must stop and contact the control operator for instructions.
Rationale: A dark signal in CTC territory is treated as a stop signal because the status is
unknown and the Control Operator must issue specific instructions for movement.
7. BNSF 3818 West is operating in ABS limits and approaches a dark signal equipped
with a number plate. What is required?
Answer: The train may pass the signal at restricted speed without stopping, and must
report the absent light to the dispatcher.
Rationale: In ABS (Automatic Block Signal) territory, a number plate indicates the signal is
not controlled by a dispatcher. The crew proceeds at restricted speed and reports the
failure.
8. A train is going to make a backup movement on the main track in accordance with
GCOR 6.6. The crew has conducted the proper job briefings and received permission
from the dispatcher. Once the movement begins, what is the maximum authorized speed
for a backup movement?
Answer: 15 mph
Rationale: GCOR 6.6 limits any reverse/backup movement on the main track to a
maximum of 15 MPH, regardless of the track speed.
9. What is the maximum speed permitted when moving a train past a stop signal without
a specific speed listed in the authorization?
Answer: 15 mph (unless otherwise specified)
Rationale: When authorized to pass a stop signal, 15 mph is the standard maximum speed
until the train is clear of the main track or has reached the next signal.
10. When approaching a passenger train stopped at a station, what speed must a freight
train be restricted to?
Answer: Restricted speed
Rationale: To protect passengers boarding or alighting, trains must approach occupied
passenger platforms at restricted speed.
