➤ 36‑Hour Slow-Line Block (January 2025)
- When: 2:00 PM Saturday, Jan 8, 2025 → 2:00 AM Monday, Jan 10, 2025
- Where: Up and Down slow lines between Thane and Diva
- Purpose:
- Integration and cut‑and‑connect of newly laid 5th & 6th lines
- Installation of crossovers, turn‑outs, derailing switches
- Yard re‑modelling and alteration of interlocking systems at Thane and Kalva stations
🚉 Impact on Train Services:
- Suburban Services:
- Kalva, Mumbra, Kopar, Thakurli stations temporarily not served
- Up slow/semi-fast trains diverted to Up fast lines between Diva–Mulund, skipping Mumbra/Kalva
- Down services similarly diverted onto Down fast line between Mulund–Diva
- Delays of ~10 minutes thereafter; commuters advised to board from Thane, Diva, Kalyan instead
- Mail/Express Trains:

🛠 Additional Block for Fast-Line Work (January 23, 2025)
- Duration: 14-hour block on Down fast line (1:20 AM to 3:20 PM), plus a 2-hour Up-line block (12:30 PM–2:30 PM)
- Purpose: Connecting old slow lines to fast corridors and commissioning new crossovers for the 5th & 6th line linkages
- Effect:
- Down Mail/Express trains diverted via slow lines; no halts at Thane for certain services
- Suburban operations bypass Kalva and Mumbra; boarding shifted to Dadar/Kalyan as needed
✅ Project Completion & Benefits
- Major Mega Block: A 72-hour mega block was executed around early February 2022 to finalize the Thane–Diva line integration.
- Completion: Work officially declared complete on Feb 8, 2025. Lines commissioned and traffic segregation implemented successfully
- Outcome: Full physical separation of suburban and long-distance traffic between Kurla–Thane–Diva corridor, improving punctuality and allowing for increased suburban train frequency.
🌍 Why This Matters
- The 5th & 6th line expansion is part of Mumbai Urban Transport Project Phase 3A, aimed at easing congestion and boosting suburban capacity on Central Railway
- While the physical blocks occurred in early 2025, their completion led to long-term benefits: smoother suburban and express operations through affected stations.
🧭 For Future Travelers & Commuters
- If traveling between Thane and Diva: Although these blocks are in the past, infrastructure updates mean service diversions and time shifts were reduced, thanks to completed track segregation.
- Expect minimal disruption today—but CR still performs periodic maintenance blocks (e.g., July 13, 2025 mega block between Vidyavihar–Thane and Harbour lines) as upgrades continue on new lines
