Statement — Railways will repair the main tracks within the city on the coming Sunday and will suspend operations for the whole day.\nCourses of Action:\nI. Railway authorities should issue public notifications well in advance to minimize passenger inconvenience.\nII. Long-distance trains entering the city during repair hours should be terminated outside city limits.

Introduction / Context:
Planned maintenance with full-day suspension requires demand management and service reconfiguration. Good practice includes early, multi-channel notifications and operational adjustments to prevent gridlock near blocked sections.

Given Data / Assumptions:

• Full-day suspension on city tracks.
• I: Advance, wide-reach communication.
• II: Short-terminate long-distance trains before the blocked segment.

Concept / Approach:
Information (I) allows passengers to reschedule or use alternatives. Short-termination (II) prevents trains from bottling up at dead ends, enables bus bridging or alternate routes, and protects work blocks. Both measures directly mitigate the operational and passenger impact.

Step-by-Step Solution:
1) Publish notices via websites, apps, stations, media.2) Replan train paths: terminate outside limits; provide shuttle/bus links where feasible.3) Coordinate with city transport for last-mile support.

Verification / Alternative check:
Railways worldwide use planned blocks with pre-announced diversions/terminations.

Why Other Options Are Wrong:
Only I/Only II/Either: incomplete. Neither: ignores essential passenger and operations management.

Common Pitfalls:
Assuming notices alone suffice without reconfiguring train operations.

Final Answer:
Both I and II follow.
