What are some interesting old photos of Kolkata Metro that showcase its history and development?
The Kolkata Metro, inaugurated in 1984, was the first underground metro railway system in India, setting a precedent for rapid transit in other urban areas.
The construction of the Kolkata Metro began in 1971, making it a significant project that spanned over a decade before its official launch.
Early ticketing for the Kolkata Metro utilized a system of coupon tickets costing 80 paise per journey; users could buy a booklet of 12 tickets for the price of 10.
The initial stretch of the Kolkata Metro, from Esplanade to Bhawanipore, was only about 3.4 kilometers long but laid the groundwork for future expansions.
Kolkata Metro's design incorporates principles of urban transit systems, emphasizing reduced traffic congestion in the densely populated city.
A notable feature of the Kolkata Metro is its elevated rail segments, which were designed to minimize land acquisition and urban displacement during construction.
The metro trains were originally imported from Germany.
These trains featured a unique design suitable for Kolkata's climate and transportation needs.
The tracks for the Kolkata Metro were built with European technology, showcasing how engineering innovations from abroad were adapted for Indian infrastructure.
Photographs from the 1970s show construction challenges, including navigating Kolkata’s dense urban landscape and its existing railway infrastructure.
The Kolkata Metro operates on a unique signaling system that allows for shorter headways, enabling trains to run frequently during peak hours.
The metro stations in Kolkata feature artistic elements that reflect local culture, integrating community identity into the transit system.
During construction, Kolkata Metro workers faced geological challenges, as they needed to navigate the city's diverse soil types, which influenced tunneling strategies.
The Kolkata Metro has undergone several expansions since its inception, now encompassing multiple lines and extending into the suburbs, thereby improving overall accessibility.
Photographs from the late 1980s depict joyful scenes of citizens experiencing metro travel for the first time, highlighting its role in everyday life.
Technological advancements over the years have led to improved safety standards in the Kolkata Metro, including automatic doors and better emergency systems.
Calcutta's historic tram service, operational since the 19th century, laid down a framework for the transition to metro transit by emphasizing public transport efficiency.
The Kolkata Metro’s design considered vibration control to mitigate impacts on nearby buildings and infrastructure, demonstrating advanced civil engineering practices.
Research shows that Kolkata Metro significantly reduces air pollution, with studies indicating a decrease in vehicle emissions due to a higher number of commuters opting for this eco-friendly transport.
