What action shall be taken by loco pilot if Guard failed to exchange all right signal after passing engineering speed restriction zone? A. Proceed further with same speed up to next station B. Proceed further with normal speed C. Stop his train and find the cause D. None of these

The correct answer is C. Stop his train and find the cause.

The loco pilot should stop the train and find the cause of the problem. This is because the guard is responsible for communicating with the loco pilot and ensuring that the train is safe to proceed. If the guard fails to exchange all right signal, it could mean that there is a problem with the train or the track. The loco pilot should not proceed until the problem has been identified and resolved.

Option A is incorrect because the loco pilot should not proceed further with the same speed up to the next station. This is because there could be a problem with the train or the track. The loco pilot should stop the train and find the cause of the problem before proceeding.

Option B is incorrect because the loco pilot should not proceed further with normal speed. This is because there could be a problem with the train or the track. The loco pilot should stop the train and find the cause of the problem before proceeding.

Option D is incorrect because it is not a valid option.
