Mumbai CSMT Redevelopment — What's Changing and When
Everything about Mumbai CSMT's massive redevelopment — new elevated decks, heritage preservation, expanded platforms, timelines, and what passengers should expect.
Chhatrapati Shivaji Maharaj Terminus — Mumbai's iconic CSMT — is undergoing one of the most ambitious railway station redevelopment projects in the world. The challenge is extraordinary: transform a station that handles three million daily passengers, preserve a UNESCO World Heritage structure built in 1888, and create a modern transit hub — all without shutting down operations.
The CSMT redevelopment is part of Indian Railways' broader station modernization program, but the scale, heritage sensitivity, and sheer passenger volume make this project unique. Here's what's happening, what's changing, and what it means for passengers.
The Plan
The redevelopment, managed by the Railway Land Development Authority (RLDA) with architectural consultants, includes:
Heritage Building Restoration
The original Victorian Gothic structure (the front building facing DN Road) is being carefully restored — not rebuilt. This includes:- Cleaning and restoring the stone facades
- Repairing the stained glass windows
- Restoring the ornate interior columns and ceiling work
- Improving lighting to highlight the architectural details
- Making the heritage wing functional for passenger use rather than just administrative offices
New Elevated Deck
A new elevated concourse deck is being built above the existing long-distance platforms (8–18), similar to the model used at Rani Kamlapati in Bhopal. This deck will feature:- Modern departure/arrival halls
- Retail and food courts
- Air-conditioned waiting areas
- Improved circulation so passengers don't need to cross tracks via overbridges
Platform and Track Improvements
- Platform widening and leveling
- Improved platform shelters and roofing
- Better drainage (Mumbai's monsoons are brutal)
- Updated signage and wayfinding
Integration with Metro and Other Transport
- Direct connectivity to CSMT Metro Station (Metro Line 1 and future lines)
- Improved pedestrian connections to BEST bus stops
- Dedicated pickup/drop-off zones for taxis and app cabs
- Multi-level parking
Suburban Section Upgrades
- Wider platforms for the suburban (local train) section
- Better crowd management infrastructure (essential during peak hours)
- Improved ventilation and lighting
What's Already Done
As of 2026, several components are at various stages:
- Heritage restoration: Active restoration of the front facade. Scaffolding is visible, but the main hall remains accessible.
- Elevated deck construction: Foundation and structural work in progress on the P. D'Mello Road side. This is where most of the active construction is visible.
- Metro integration: CSMT Metro station is operational and connected.
- Platform improvements: Some platforms in the long-distance section have been upgraded.
- Digital signage: New electronic display boards installed across most platforms.
Impact on Passengers Right Now
What's Changed
- Some entrances may be temporarily rerouted. The P. D'Mello Road entrance on the long-distance side has seen the most disruption. Follow temporary signage.
- New digital boards make platform identification easier than before.
- Metro connectivity is live — use it to avoid road traffic to CSMT.
What Hasn't Changed
- All platforms remain operational. No platforms have been taken out of service for the redevelopment.
- Suburban local train services continue as normal from platforms 1–7.
- Long-distance services continue from platforms 8–18.
- The heritage main hall is accessible and functioning.
Temporary Inconveniences
- Construction barriers in some corridors, particularly near the P. D'Mello Road entrance
- Noise and dust in construction-adjacent areas
- Some walkways temporarily narrowed
- Parking areas reduced during construction
When Will It Be Complete?
The full redevelopment is expected to be completed in phases over the next few years. Heritage restoration and the elevated deck are the major milestones. Given Mumbai's construction challenges (monsoon season halts, regulatory clearances, the sheer complexity of working over live rail tracks), exact timelines are fluid.
The key point: CSMT never closes. Work happens around live operations, which is slower but ensures the three million daily passengers are never left stranded.
Heritage vs Modern: The Design Challenge
CSMT's redevelopment walks a tightrope between preserving a 130-year-old UNESCO Heritage building and creating a modern transit hub. The approach is:
- Heritage zone (front building): Restore, don't rebuild. Maintain the Victorian Gothic character. Clean the stone, fix the stained glass, light it properly.
- Modern zone (elevated deck, rear sections): Build new. Use contemporary design that complements but doesn't mimic the heritage building.
- No demolition of heritage elements: UNESCO oversight ensures the original structure is protected.
How This Compares to Other Redevelopments
| Station | Status | Approach |
|---|---|---|
| Rani Kamlapati (Bhopal) | Completed | Elevated concourse, new build |
| Gandhinagar Capital | Completed | Hotel above tracks |
| Ayodhya Dham | Completed | New build, temple-inspired |
| New Delhi (NDLS) | In progress | Phased redevelopment |
| Mumbai CSMT | In progress | Heritage + modern hybrid |
| Howrah | Planned | Mega-scale redevelopment |
Tips for Current Passengers
Tip 1: Use the metro to reach CSMT when possible. Road-side construction has reduced parking and drop-off space. Tip 2: The DN Road entrance (heritage building side) is less affected by construction than the P. D'Mello Road entrance. If you're heading to long-distance platforms, enter from DN Road and cross internally. Tip 3: Allow extra time during your visit. Construction diversions can add 5–10 minutes to your platform walk. Tip 4: Check IndianRail.app for platform assignments before entering — knowing your platform saves you from navigating construction-affected corridors unnecessarily. Tip 5: The heritage building is worth admiring even amidst construction. Look up at the central dome, the gargoyles, the ornate columns. This is one of the finest Victorian Gothic buildings in Asia.What CSMT Will Look Like After
When completed, CSMT will be:
- A world-class transit hub handling suburban trains, long-distance trains, and metro — all integrated
- A restored UNESCO Heritage building that showcases Mumbai's colonial architectural legacy
- A modern commercial center with retail, food, and hospitality
- An accessible station with elevators, escalators, and proper wayfinding
- A model for how India handles heritage conservation alongside modern infrastructure development
The bones of the old CSMT — the grand arches, the stone facades, the soaring central hall — will remain. Around them, a 21st-century station is being built.
