[amp_mcq option1=”1 in 400 OR Steeper” option2=”ST 1- IN 400″ option3=”1 in 260″ option4=”None of these” correct=”option1″]
The correct answer is: A. 1 in 400 OR Steeper
Hand shunting of wagons is totally prohibited in gradients of 1 in 400 or steeper. This is because the wagons can become unstable and derail if they are shunted on a gradient that is too steep.
Option B, ST 1- IN 400, is not a valid option. Option C, 1 in 260, is a valid option, but it is not the correct answer. Option D, None of these, is not a valid option.
