This means that the train must continue sounding the whistle until someone from each work group acknowledges the train's approach either through a radio communication or a hand signal. This ensures that all workers are aware of the train's presence and can take appropriate safety measures.

Submit
87. In Rule 261 territory, how must movement be made at points where crews change, unless a leaving signal is provided?

Explanation

When crews change in Rule 261 territory, movement must be made at Restricted Speed until the leading end of the movement reaches the next signal. This means that the train must proceed at a speed that allows it to stop within half the range of vision, be able to take any other necessary action to avoid an obstruction, and be able to stop before any switch not properly lined or a train on the same track ahead. This ensures safety and allows the crew to react appropriately to any potential hazards or changes in the track ahead.

Submit
88. What must the employee receiving a mandatory directive state before the mandatory directive is transmitted?

Explanation

The correct answer is that the employee must state their identification, location, and readiness to receive the mandatory directive. This is necessary in order to ensure that the employee is properly identified and located, and that they are prepared to receive and follow the mandatory directive. By stating their identification and location, the employee can be easily identified and located by the Train Dispatcher/Control Operator, and by stating their readiness, they are confirming that they are prepared to copy and act upon the directive.

Submit
89. What does a caution (yellow) sign placed to the right of the track in direction of approach indicate and where would it be displayed?

Explanation

The caution (yellow) sign placed to the right of the track in the direction of approach indicates that the train is approaching a temporary speed restriction. This sign is displayed 1 ½ miles in advance of the point at which the speed is temporarily restricted. The purpose of this sign is to alert the train operator to slow down and be prepared to reduce their speed at the designated point. This allows for safe and controlled operations in areas where temporary speed restrictions are in place.

Submit
90. In the absence of a slow order or other instructions, how must a train be governed if a caution (yellow) sign is observed?

Explanation

When a caution (yellow) sign is observed and there are no slow orders or other instructions, the train must approach prepared to stop short of a conditional stop sign. The train must not exceed a speed of 10 MPH until the trailing end of the movement has passed a proceed (green) sign placed to the right of the track. This ensures that the train proceeds with caution and maintains a safe speed until it is clear to proceed at the authorized speed.

Submit
91. What must the employee advise the Train Dispatcher/Control Operator, when reporting "clear" of track authority limits in non-signaled territory and a hand-throw main track switch has been operated?

Explanation

The employee must advise the Train Dispatcher/Control Operator that all main track switches operated have been restored and secured to their normal position. This is important to ensure the safe movement of trains and to prevent any potential accidents or disruptions on the track. By confirming that the switches have been restored and secured, the employee is ensuring that the track is clear and ready for further movement.

Submit
92. How may a train proceed beyond the Conditional Stop Sign designated in Form Y, or enter main track between the limits of Form Y? 

Explanation

The correct answer is that the Engineer must be notified by the employee in charge of the working limits that the track is clear. This means that before proceeding beyond the Conditional Stop Sign or entering the main track between the limits of Form Y, the Engineer must receive confirmation from the employee responsible for the working limits that it is safe to proceed. This ensures that there are no potential dangers or obstructions on the track that could pose a risk to the train's movement.

Submit
93. When must the engine horn be sounded when approaching public highway-rail crossings, when trains and engines are exceeding 45 MPH?

Explanation

When approaching public highway-rail crossings, the engine horn must be sounded to alert pedestrians and motorists of an oncoming train. According to the given answer, the signal should be initiated at or about the whistle post, which is a designated location before the crossing. It should not be started more than one-fourth (1/4) mile from the crossing, but it should not be less than 15 seconds before occupying the crossing. This ensures that there is enough time for the warning to be heard and for people to safely clear the tracks before the train passes.

Submit
94. When an Authority Form is transmitted by radio directly to a train, who may copy and repeat it?

Explanation

When an Authority Form is transmitted by radio directly to a train, it must be copied and repeated by a crewmember on the controlling unit. However, it must not be copied or repeated by an employee operating a moving locomotive. This ensures that the information is accurately received and understood by the crew responsible for controlling the train's movement. The restriction on copying and repeating by an employee operating a moving locomotive is likely to prevent distractions and maintain focus on the safe operation of the train.

Submit
95. In Rule 251 territory, how must movements that are authorized to operate against the current of traffic be made?

Explanation

In Rule 251 territory, movements that are authorized to operate against the current of traffic must follow all of the mentioned conditions. They must be authorized on a Form of Track Authority, approach facing-point switches at Restricted Speed unless advised otherwise, and receive verbal authority from the Train Dispatcher/Control Operator to resume operation with the current of traffic according to ABS rules. All of these answers are correct.

Submit
96. When would Caution (yellow) and Proceed (green) signs be used?

Explanation

Caution (yellow) and Proceed (green) signs would be used for slow orders placed in effect by Operations Bulletin. This means that when there is a temporary speed restriction or a slow order in place, these signs would be displayed to notify the train engineer to proceed with caution at a reduced speed. This ensures the safety of the train and helps prevent accidents or derailments in areas where there may be track maintenance or other hazards.

Submit
97. How must a train or engine proceed when approaching an automatic interlocking-railroad crossing at grade? 

Explanation

The correct answer states that a train or engine must proceed prepared to stop when it has stopped, or is moving less than 25 MPH, while approaching or after passing the distant signal. This means that the train or engine should be cautious and ready to stop if it has already come to a stop or if it is moving at a speed less than 25 MPH while approaching or after passing the distant signal. This ensures safety and allows for appropriate response in case of any potential hazards or obstructions on the railroad crossing.
