Today, we talk about bullet trains, but there was a time when trains ran on steam. With 16 zones, India's railway network is one of the largest in the world.
Here, trains are considered as an important lifeline that connects all corners of the country and binds together over one billion people of this country.
It has been a connecting link for those who have to travel in different states, all across India. Let us go through the changing face of Indian railways:
In December 1851, first steam engine Thomason was operated in Roorkee. second was named after Bombay governor as Lord Falkland, third was used as trial run of the passenger train in Nov 1852.
In 1970, the last steam locomotive was rolled out of Chittaranjan Locomotive Works. By 1985, steam locomotives were phased out.

Fairy Queen, one of the oldest working steam locomotives in the world, has gained tourist attraction because it is the oldest steam engine in operation hauling luxurious train from Delhi to Alwar.
India's debut with official train
With the modest beginning, India's first train was flagged off on Saturday, April 16, 1853 from Bori Bunder, Mumbai to Thane for a distance of 33.81 kms. 400 passengers first experienced the travel in the train of 14 coaches.
Interestingly, the Bombay government had declared that day as a public holiday.
Diesel train: No looking back
To combat the problems faced by steam engine trains, diesel trains were launched, that were faster.
Diesel Locomotives are fitted with Auxiliary Power Units which saves nearly 88% of fuel during the idle time when train is not running.
In 1904, the idea to electrify the rail network was proposed.
On Feb 3, 1925, first electric train made debut between Bombay (Victoria Terminus) and Kurla, a distance of 16 kms
Electric Multiple Unit (EMU) coaches are used for suburban traffic in large cities - mainly Mumbai, Chennai, Delhi, Kolkata, Pune, Hyderabad and Bangalore.
In July 2014, India's first semi-high speed bullet train or high-speed train had a successful trial run from Delhi to Agra in 90 minutes only. It is likely to be fully operational in 2015, with the name of "Gatimaan Express", with a maximum speed of 200 km/h.
The current fastest train in India is the Bhopal Shatabdi that runs with a top speed of 150 km/h.
After Lok Sabha elections 2014, Modi government promised to build the Diamond Quadrilateral project, which would connect via high-speed rail the cities of Chennai, Delhi, Kolkata, and Mumbai.
