CTC - Centralized Traffic Control Day 1 & 2
questions with accurate answers
10.1 Authority to Enter CTC Limits/Signal Governing Movement Over
a Hand-Operated Switch Ans✓✓✓ CTC limits are designated in the
timetable. Sidings within CTC limits are controlled sidings and are
governed by CTC rules.
A train must not enter or occupy any track where CTC is in effect unless
a control signal displays a proceed indication or the control operator
authorizes: Signal or Verbal Authority.
3 types of verbal authority:
1. Movement past a Stop indication under rule 9.12.1 (CTC Territory)
2. A train to enter track between block signals as follows:
"(Train) at (Location) has authority to enter (track) and proceed
(direction)."
3. Track and Time under Rule 10.3 (Track and Time)Signal Governing
Movement Over a Hand-Operated Switch
If a signal governs movement over a hand-operated switch that is not
electrically locked, the control operator must authorize the train to enter
or occupy any track where CTC is in effect before the switch is opened.
After the switch is opened, if the signal does not display a proceed
indication, a crew member must wait 10 minutes at the switch. After the
10 minute wait, if the signal does not display a proceed indication, move
the train at restricted speed and notify the control operator.
However, if the block to be entered is occupied by its own standing train
or when the hand-operated switch remains opne, the movement may,
after stopping, pass an absolute signal displaying a Stop indication
without waiting 10 minutes and without contacting the control operator.
,10.2 Clearing Through Hand-Operated Switches Ans✓✓✓ Where CTC
is in effect, a train must not clear any track at a hand-operated switch not
equipped with an electric switch lock, except under one of the following
conditions:
1. Where the permanent maximum authorized speed does not exceed
20MPH on the main track or a controlled siding equipped with an
intermediate signal.
2. Where the permanent maximum authorized speed does not exceed 30
MPH on a controlled siding no equipped with an intermediate signal.
For First 2 Bullets, Note: The speed restriction is a permanent speed.
You cannot put out a Track Bulletin reducing speed to 20 MPH at that
location to set out a unit.
3. Where a signal governs movement to a track where CTC is in effect.
4. When the hand-operated switch is kept open.
Note: the train itself can "Get in the Clear" or leave the main track if the
switch is left open so another train cannot get by.
20.24.2 Controlled Track Occupied without Authority
Reference GCOR 1.4 and 9.5 Ans✓✓✓ When a train or employee
occupies a controlled track without authority, or authority is
released/voided in error leaving train or employee unprotected, the
dispatcher must immediately:
Trains:
1. Instruct the train to stop and remain stopped.
2. Warn any conflicting movements or employees holding authority in
the affected limits.
3. Protect the location.
, Train must not be allowed to proceed until released by field management
officer, Corridor Director/Manager or proper supervisor.
Employees:
1. Instruct the employee to immediately clear the track if possible.
2. Warn any conflicting movements or employees holding authority in
the affected limits.
3. Protect the location.
If the authority was released or voided in error by the train dispatcher,
the requirement to stop the train or have the employee clear the track
does not apply.
Notify Corridor Director/Manager of incident.
20.8 Requirements for Granting Authority Ans✓✓✓ When transmitting
or accepting release of, authorities; or when transmitting any other
mandatory directive or instruction in the CAD system, the train
dispatcher or control operator must directly observe the screen display to
ensure the employee's repeat is correct.
When transmitting authority, mandatory directive, or instruction; or
when confirming the limits of authority that includes a control point,
state the location as either "CP" or "Control Point" followed by the
alphanumeric designation(e.g., "CP A010"). When confirming the limits
of authority that include a milepost , state the location as either "MP" or
"Milepost."
