A material train may be divided outside station limit during emergency under the supervision of ________. A. Guard B. PWI C. Driver D. None of these

The correct answer is: A. Guard

A material train may be divided outside station limit during emergency under the supervision of the Guard. The Guard is responsible for the safe operation of the train and will ensure that the division is carried out safely and in accordance with the relevant regulations.

The PWI (Permanent Way Inspector) is responsible for the maintenance of the track and infrastructure, and would not be involved in the division of a train. The Driver is responsible for the operation of the train, but would not be responsible for the decision to divide the train.

Option D is incorrect because the Guard is the only person who is authorized to supervise the division of a train outside station limits during an emergency.
