In double shot GT, a train is always approaching which type of signal?

• A. A yellow signal with an illuminated S
• B. A red signal with a lunar light
• C. A green signal for proceed
• D. A white caution signal

Answer: (A)

In the context of double shot GT (Grade Crossing Protection), the correct signal that a train is always approaching is a yellow signal with an illuminated "S." This type of signal indicates caution and serves as an important warning for the train operators. The yellow signal typically suggests that the train must reduce speed and be prepared to stop, as it may encounter a red signal or other signals indicating that caution must be exercised. This signal system is designed to enhance safety by providing clear communication to train crews well in advance of potential hazards on the track. In a double shot GT scenario, the illuminated "S" can signify specific conditions or instructions that pertain to the train's routing or the presence of hazards ahead that require the crew's attention. The other signal options represent different aspects in train operations but do not align with the requirements of double shot GT. A red signal with lunar light traditionally signifies a stop, while a green signal indicates a clear track for proceeding. A white caution signal is not a standard signal used in this context, further distinguishing why the yellow signal with an illuminated "S" is the correct choice.
