Statement : As many as ten coaches of a passenger train have derailed and blocked both pairs of the railway tracks.

Courses of Action :
I. The railway authorities should immediately send men and equipment to the spot to clear the railway tracks.
II. All the trains running in both the directions should be diverted to other routes.

Explanation:-

The situation demands first diverting other trains to different routes so as to avert any accident, and then clearing the tracks as soon as possible. Thus, both the courses follow.
