General signal rules apply where special instructions, dispatcher message, or Form EC-1 designate what authorities for movement are in effect?
- TWC-ABS Track Warrant Control with Automatic Block Signals
- YL-S Main Track Yard Limits Signaled

- CP Control Point
- ref 504.1
How must trains approach the beginning of signaled territory?
- Prepared to comply with the first signal
- ref 504.2
Movements not governed by fixed signal indication must receive permission of the Train Dispatcher. Once the Train Dispatcher gives permission: (1) At what speed may you proceed? (2) How far does the required speed apply?
- 1. Restricted speed
- 2. To the next signal or to the end of signaled territory if the movement is to enter non-signaled territory
- ref 504.3
You are operating on an Approach signal. The next signal is Clear. When may you act on the Clear indication?
- When next governing signal can be plainly seen
- Rear of movement has passed through all crossovers and turnouts, AND
- Train is not required to operate at restricted speed
- ref 504.4
How far does a signal requiring restricting speed apply?
- Until leading end of train reaches next governing signal
- ref 504.5
When a signal aspect requiring Restricted Speed is displayed when moving into non-signaled territory, it will apply until:
- Entire movement clears turnouts and crossovers, AND
- Leading end of the train reaches the end of signaled territory
- ref 504.5
Should it be observed that a train fails to actuate a signal to display the proper aspect, what is the necessary procedure?
- Attempt to stop other trains involved, AND
- Notify Train Dispatcher
- ref 504.6
What are you required to do if you stop less than one locomotive length short of an Absolute signal?
- Get permission from Train Dispatcher to proceed
- ref 504.7
At what speed must a train proceed when it is stopped for any reason after passing a block signal (not requiring restricted speed) in COT, TC, & CP territory?
- Proceed prepared to stop at the next signal, and
- Do not exceed 40 MPH, unless governed by a slower speed
- ref 504.8
You pass a Clear indication on a signal governing the approach to a home signal not at a railroad crossing at grade or the beginning of signal territory. If your train's speed is reduced to 10 MPH, how must you approach the home signal?
- Approach home signal prepared to stop,
- Not exceed 40 MPH unless governed by a slower speed, AND
- Resume the speed authorized by the distant signal when the home signal is seen to display a proceed indication
- ref 504.9b
You pass a Clear indication on a signal governing the approach to a railroad crossing at grade. If your train speed is reduced to 15 MPH after passing the Clear signal, how must you approach the signal at the railroad crossing at grade?
- Prepared to stop
- ref 504.9a
What authorization is needed to open a switch to a signaled track?
- Signal Indication, or
- Permission of Train Dispatcher
- ref 504.13
You have been given permission to take the power-operated switches off of power and place them in hand operation. How may you operate by the Stop signal that governs the switch?
- Can go by Stop signal without permission at Restricted Speed
- ref 504.15
After restoring the switches to motor or power position, how may a train proceed?
- Signal Indication, or
- Permission of the Train Dispatcher
- ref 504.15
If a train has permission of Train Dispatcher to make a reverse movement within limits of the same block, how must the movement be made?
- Restricted Speed with a crewmember located on the rear of the movement
- ref 504.16
How can a train make a reverse movement within the limits of the same block without permission of the train dispatcher?
- Restricted Speed, AND
- A crewmember or other qualified employee is positioned on the ground ahead of the leading end prepared to stop any opposing movement
- ref 504.17
What is required if a train passes a Stop signal without permission?
- Notify Train Dispatcher, AND
- Provide warning against approaching trains
- ref 504.20
What must you do if a signal displays a Stop aspect unless the reason for such aspect is apparent?
- Promptly notify Train Dispatcher
- ref 504.19
What must you have in order to pass a Stop Signal?
- Permission from Train Dispatcher
- ref 504.21
Can you pass a stop signal without permission of Train Dispatcher when necessary to recouple to your train located immediately beyond the signal and no power operated switches are involved?
If a train operating on a signal indication more favorable than Approach encounters a Stop signal or a signal requiring Restricted Speed, what must the train do?
- Comply with signal indication consistent with good train handling unless conditions require and emergency brake application, AND
- Report incident to Train Dispatcher
- ref 504.27
Promptly report a signal imperfectly displayed to the train dispatcher and regard the signal as the most restrictive indication that can be conveyed by that signal, unless
- One or more lower units of a color light signal aspect is dark, the aspect is to be observed as though the lights that should be displayed wre displayed RED. Does not apply to C-1290(a)
- ref 504.28d
If, during the course of your trip, you discover a signal that is imperfectly displayed or do not find a fixed signal where one is usually displayed, what must you do?
- The most restrictive indication that can be given by that signal governs the movement
- Report absence of signal to Train Dispatcher
- ref 504.29
Train crews observing an improper signal aspect permitting a train to proceed must:
- Bring train to a safe and normal stop before passing signal,
- Notify Train Dispatcher and be governed by his instructions, AND
- Provide warning for approaching trains until relieved by Train Dispatcher
- ref 504.30
Obtain permission from the train dispatcher to assist a standing train. After receiving permission from the train dispatcher, a locomotive may be permitted in the same block to assist a standing train provided:
- Train dispatcher is informed that a clear understanding exists between all crewmembers as to the location of the standing train
- A crewmember of the standing train provides warning against the assisting locomotive
- ref 504.31
What information must you give the train dispatcher when leaving equipment unattended on a controlled track?
- Specific locations of both ends of equipment
- Identifying initials and number of the locomotive or the car at each end of equipment
- Total number of locomotives and cars, AND
- The information provided is confirmed to be correct by all crewmembers
- ref 504.32
What must you do when the Train Dispatcher grants authority to remove unattended equipment from a controlled track once the Train Dispatcher verifies that a clear understanding exists among crewmembers as to the location of the standing equipment?
- Stop one-quarter mile from the standing equipment, AND
- Approach the location of the standing equipment at Restricted Speed
- ref 504.33
When removing unattended equipment from a controlled track, advise the train dispatcher of:
- Number of locomotives and cars moved, AND
- Identifying initials and number of locomotive or car at each end of equipment
- ref 504.34
Special Instructions, Dispatcher Message, or Form EC-1 may temporarily remove block signals and signal rules from service. When signal system is suspended, what must happen?
- Establish an alternate method of operation, AND
- Notify all trains affected
- ref 504.36
Unless otherwise specified, when signals are temporarily removed from service, trains must:
- Approach all Absolute signals prepared to stop and not pass these signals without permission of train dispatcher

- ref 504.37
Under certain conditions, what may fail to activate the block signals or highway-rail crossing at grade warning devices? (shunting signal)
- Single car or single light locomotive
- ref 504.38
