[amp_mcq option1=”T/409″ option2=”T/B-409″ option3=”T/C-409″ option4=”None of these” correct=”option1″]
The correct answer is: A. T/409
Notice station caution order No. is T/409. It is a notice to all train crews and other personnel working on or near the railroad that there is a potential hazard on the track. The order includes information about the hazard, such as its location, type, and severity, as well as instructions on how to avoid it.
Option B, T/B-409, is not a valid notice station caution order number. Option C, T/C-409, is also not a valid notice station caution order number. Option D, None of these, is also incorrect.
