BNSF EXAM 2 QUESTIONS AND
ANSWERS COMPLETE AND ACCURATE.
When a train requests permission to pass a Stop indication in ABS do the
following_____________________
· Verify that the train has authority beyond the Stop indication.
· Attempt to verify that no opposing train has violated its authority.
The train dispatcher may then give the train permission to pass the signal
When issuing a track warrant for trains in Non- Signaled territory the
authority must end at_______________
the open switch
When Issuing an authority to MW in Non-Signaled, what restrictions for
protect open switches exist?
No restrictions in any territory for MW
When Issuing a Form B a verbal safety briefing must occur to determine
the following___________________________
· What track(s) will be occupied or fouled,
· Where work will be performed
· Which, if any, of the dual control switch(es) in the limits will be occupied or
fouled, ·
What, if any, routing restrictions exist for train movements through the limits.
When dual control switch or switches in a control point do not indicate to
be lined and locked, movement must be authorized past the Stop
indication and employee instructed to operate dual control switch(es) by
hand. Before doing so:
,Apply Blocking to all switches at the location
Apply track blocks on the track segment beyond the affected control point.
Before authorizing a change of direction to a train that has entered a block
on a signal indication first _______________________________
Verify no conflicting authorities exist
Apply track blocks to affected limits
Before transmitting track and time
confirm______________________________
track blocks have been applied to the control machine to prevent movement
into the authorized limits while track and time is in effect
When a train crew has reported unusual or rough track conditions instruct
the crew to traverse the track at___________________________
Restricted speed not exceeding 20mph until the rear of the train has traversed
the entire length of rough track.
Notify Chief
When notified of a track condition or obstructions i.e (cows) unless the
report includes specific Mile Post include a ______________________
one mile buffer in each direction of the reported condition.
Absolute Signal
A block or interlocking signal without a number plate, or designated by an A
marker.
Block Signal
A fixed signal at the entrance of a block that governs trains entering and using
that block.
, Control Point
The location of absolute signals controlled by a control operator.
Controlled Siding
A siding within CTC or interlocking limits where a signal indication authorizes
the siding's use.
Crossover
A track connection between two adjacent, not necessarily parallel tracks,
consisting of a minimum of two switches, which is intended to be used
primarily for the purpose of crossing over from one track to another.
Centralized Traffic Control (CTC)
A block system that uses block signal indications to authorize train
movements.
Current of Traffic
The movement of trains on a main track in one direction, as specified by
special instruction.
Electric Switch Lock
An electronically controlled lock that restricts the use of a hand-operated
switch or derail.
interlocking
Signal appliances that are interconnected so that each of their movements
follows the other in a proper sequence. Interlockings may be operated
manually or automatically.
Interlocking Limits
The tracks between outer opposing absolute signals of an interlocking.
