I couldn’t locate any official or confirmed announcement regarding a mega block on Sunday, 20 December 2025 in Mumbai or other Indian Railways zones. Here’s what’s known:

---

❌ No Mega Block Found for 20 December 2025

• No public railway press releases or local bulletins specify a mega block set for 20 December 2025, unlike blocks observed for dates such as 20 July 2025 or 22 June 2025turn0search7turn0search2turn0search4.
• Historical mega blocks are typically announced 1–3 weeks in advance, often via railway zone websites or official X/Twitter channels (e.g., Central Railway), and none currently list that dateturn0search3turn0search9.
• Mumbai mega blocks in mid-2025 were tied to July and June maintenance dates, not December schedulesturn0search2turn0search14turn0search16.

---

🕒 What Might Be Happening Instead

• While there’s no mega block planned on 20 December 2025, rail zones often release night or traffic blocks closer to the date for localized maintenance.
• Special night traffic blocks on 20/21 December were previously scheduled on sections like Khadavli–Titwala by Central Railway in July 2025turn0search3—a pattern that could repeat.

---

✅ TL;DR

• No confirmed mega block is scheduled for 20 December 2025 as of now.
• Blocks are usually disclosed a few weeks prior. It’s possible notices haven’t been issued yet.
• If you’re planning travel around that date, it’s too early to confirm any disruptions.

📌 Suggested Next Steps

1. Check official zone websites and social media (e.g., @Central_Railway) from early to mid-December 2025 for mega block advisories.
2. Use NTES or RailMadad services for real-time updates on train status and service changes.
3. If you have a specific train number or route, I can monitor it and alert you once announcements surface.

Would you like me to track updates for your particular route or set reminders to check railway bulletins closer to that date?
