A Tapestry of Heritage and Culture of Kolkata

Kolkata a city of magnificent contrasts, steeped in history yet brimming with modern energy has marched steadily into the 21st century. Steeped in colonial-era architecture, intellectual legacy, vibrant arts, and pulsating street life, Kolkata has been reinventing itself while retaining its timeless charm. A fascinating example of this urban renewal is the electric water metro, locally known as the Dheu Electric Cruise, gliding serenely along the Hooghly River. In this article, we’ll explore Kolkata’s cultural heartbeat, infrastructure marvels, and environmental footprint, with a special spotlight on its new electric water metro.


A Tapestry of Heritage and Culture

Kolkata, often called the City of Joy, earned its name through a glorious tapestry of culture. From literature and cinema to performing arts and academia:

1. Literary & Intellectual Capital: Home to Rabindranath Tagore, Bankim Chandra Chattopadhyay, and Satyajit Ray, Kolkata’s literary traditions are among India’s richest.
2. Collegiate Legacy: Institutions like Presidency College and Jadavpur University shaped generations of thinkers and professionals.
3. Festivals & Theatrics: Durga Puja, the grandest festival, transforms the city into a fantasia of art, light, and devotion, while theatre troupes and cultural academies thrive year-round.
4. Café & Art Scene: College Street’s centuries-old bookshops, vibrant cafés, and galleries like the Academy of Fine Arts bridge the gap between past and present.

Commuting Through Time: Metro Rail Revolution

Kolkata launched India’s very first metro system in October 1984, marking a major milestone in urban transit . Over the decades, this network has constructed a modern ring—Blue, Green (East‑West), Purple, and Orange lines—encircling the city and its suburbs.

• The Blue Line (Dakshineswar–Kavi Subhash) spans 31 km, carrying over 700,000 passengers daily .
• The Green Line (Line 2) includes the nation’s first underwater tunnel beneath the Hooghly, linking Howrah Maidan with Esplanade via a 4.8 km stretch inaugurated on 6 March 2024 .
• Purple and Orange lines, though still expanding, now weave through key nodal points across the metro grid .

Each segment underground, elevated, or beneath the riveremploys advanced tunnel-boring techniques and eco-friendly systems. Service extensions, like more frequent Purple Line trains, reflect how transit continuity is woven into the city’s pulse .


The Hooghly: Kolkata’s Waterway Renaissance

For centuries, ferries have linked the banks of the Hooghly, ferrying commuters and trading goods. Until early 2025, most vessels relied on aging diesel engines, producing noise and emissions. That changed with the arrival of Dheu, Kolkata’s first fleet of zero-emission electric ferries .


A Green Marvel

• Constructed by Garden Reach Shipbuilders and Engineers (GRSE) for ₹13.5 crore, Dheu is the state’s first indigenous fully electric ferry .
• Its catamaran hull design—developed with IIT Kharagpur—minimizes wave impact and enhances stability .
• The ferry seats 92 passengers in AC and non-AC sections, creating a peaceful and comfortable journey .

Routes, Tickets & Timings

Launched on 9 January 2025, Dheu’s route brings relief and enchantment to river commuters :

• Departure & return: Millennium Park Jetty (near BBD Bagh / Dalhousie Square)
• Route highlights: Howrah Bridge, Bally Bridge, Dakshineswar Temple, Belur Math
• Daily schedule: One round-trip at 4:30 PM (closed Wednesdays)
• Duration: ~2 hours, timed to coincide with sunset and golden-hour calm
• Ticket pricing:
  • Non‑AC: ₹200
  • AC (includes snacks/tea): ₹300  
• Booking: Offline, via the counter at Millennium Park Jetty

Integration and Impact: What Dheu Brings

Environmentally, the ferry reduces carbon emissions and diesel noise, representing a transformative shift in Kolkata’s river transport .
Urban mobility gains a new dimension allowing commuters to bypass congested roads and experience the city from the riverbanks.
Tourism benefits too: a riverside glide past landmarks makes for an unforgettable experience, melding history with innovation.
Economic vitality rises through job generation (e.g. crew, maintenance, ticketing) and revitalizing ghats and riverside promenades. Visitors often combine a Dheu ride with visits to Howrah Bridge, Belur Math, or Dakshineswar Temple.


Kolkata’s Sustainable Future
Dheu’s launch aligns neatly with larger sustainability initiatives across the Kolkata Metro:

• The Green Line uses solar panels and energy-efficient systems, tapping renewable energy to power operations 
• Waterway revival projects integrate Dr. Mahatma Gandhi Road, ghat beautification, and river-based transit planning.
• The Upgrading Sun Beltincluding south Kolkata’s water treatment and booster systems—is improving living standards along the riverfront .

The synergy between terrestrial metro lines, underground river tunnels, and the new electric vessel symbolizes a greener, more connected city.


Challenges & the Road Ahead

Executing projects like Dheu and the underwater metro hasn’t been easy:

• Underwater tunnelling demanded waterproofing and precision engineeringhydrophilic gaskets had to ensure no river ingress for decades to come .
• Multi-use shafts, intricate machinery, and phased commissioning meant complex construction logistics.
• Electric ferry rollout required staff training and maintenance restructuringthough any teething issues were quickly addressed through careful planning.

Looking forward:

• Satellite lines may integrate more electric ferries along the Hooghly and its tributaries.
• Metro connectivity with waterfront jetties would create holistic urban mobility.
• Feasibility studies—inspired by successes like Kochi’s Water Metro—are underway for similar projects in Mumbai, Guwahati, Goa, and Kolkata .
• Plus, increased rakes for Purple and Orange lines will improve reliability and frequency .

The Allure of Kolkata: Land, River, Tunnel

Kolkata’s charm lies in its diverse transport tapestry:

• Land-based: Iconic black-and-yellow cabs, trams, and the sprawling metro.
• Underland: Beneath the Hooghly, passengers zip across in under a minute through the East-West Metro.
• River: Above water, Dheu charts a new course—quiet, green, immersive.

Whether you’re commuting for work, visiting the Victoria Memorial, or savoring street-side mishti doi, Kolkata now offers a spectrum of travel modes that feel more integrated and experiential than ever.



Final Words

Kolkata has always been a storyteller: a city of bridges, ghats, colonial mansions, and passionate conversations. But with the electric water metro, it adds a new verse—one where ecology, engineering, and the river’s timeless flow intersect. The dawn of Dheu marks a leap toward a greener, more connected future, complementing the city’s rich traditions. As Kolkata’s underwater tunnels hum and electric ferries glide under the Howrah Bridge, the City of Joy is doing more than evolving: it’s redefining urban life itself.

For travelers and locals alike, Kolkata in 2025 is not just a destination it’s an experience, with every bridge, every metro, every wave across the water echoing a grand narrative of progress amid heritage.
