Statement–Courses of Action (rail disruption & contingency): Ten coaches of a passenger train have derailed, blocking <em>both</em> pairs of railway tracks on the section; which course(s) of action logically follow—(I) immediately dispatch men and equipment to clear the tracks, and (II) divert all trains in both directions via alternative routes?

Given data

• A major derailment has blocked both up and down lines.
• Course I: send teams and machinery to clear tracks immediately.
• Course II: divert traffic both ways to alternate routes.

Concept/Approach (immediate restoration + traffic management)
A logical response combines clearing the obstruction and managing traffic flow to avoid cascading delays and safety risks.

Step 1: Course I
Removes the physical blockage; essential for restoration.

Step 2: Course II
Maintains operations by re-routing until normalcy returns.

Verification/Alternative
Railway emergency protocols routinely do both in parallel: clear + divert.

Final Answer
Both I and II follow.
