Indian Railways to run magnetic trains soon

Indian Railways to run magnetic trains soon

Trains that can travel 500 km an hour may soon become a reality in India, as the Indian Railways is mulling options to run trains on magnetic tracks.

The Suresh Prabhu-led ministry of railways has floated a tender on August 4 to explore opportunities of maglev trains in India, which can hit 500 kmph. Maglev is a transport method that uses magnetic levitation to move vehicles without touching the ground. A maglev train floats above the tracks on a "cushion" of magnetic field.

A vehicle can travel along a guideway using magnets to create both lift and propulsion, thereby reducing friction by a great extent and allowing high speeds. Magnets on the track push and lift the train up in the air by about 1 inch to 6 inches. These "track" magnets are controlled by a computers which keep shifting forward the magnetic force of the "track" magnets so that the vehicle is pulled forward.

Indian Railway plans ‘Mission 350 Plus’ to build Bullet Train coaches, MagLev trains

Indian Railway plans ‘Mission 350 Plus’ to build Bullet Train coaches, MagLev trains 

Indian Railways is planning various Bullet Trains coaches and MegLev Trains across the country, apart from the Mumbai-Ahmedabad one

Mumbai: In the biggest scale-up of its ambitions so far, the Indian Railways has set up two committees – one to shepherd its plans to build bullet train coaches capable of running at speeds higher than 350 km per hour, and the second to explore the feasibility of running trains based on magnetic levitation or MagLev trains, as they are known worldwide.

The bullet train coach plan, christened Mission 350 Plus, will be headed by Inderjeet Singh, Executive Director (Carriage) at the Research Design and Standards Organisation (RDSO), the railway’s apex technical body. The MagLev exploration committee will be headed by Nitin Chowdhary, currently Executive Director, Mechanical Engineering (Development) at the Railway Board. Both the committees have been given two months to submit their reports. The two plans were discussed extensively under the ‘future readiness’ module of the Indian Railways’ Chief Mechanical Engineers Conference held at Ooty in Tamil Nadu recently.

Over 45 of the Railways’ top mechanical engineering officers, led by member (mechanical), Hemant Kumar, attended the conference. The move comes in the backdrop of the Railways firming up studies for various bullet train routes across the country, apart from the Mumbai-Ahmedabad one.

These routes include Delhi-Chennai, Delhi-Mumbai, Delhi-Kolkata and Mumbai-Chennai, all part of the Railways’ High Speed Diamond Quadrilateral as well as routes like Delhi-Agra-Lucknow-Varanasi-Patna, Hyderabad-Chennai and Chennai-Bengaluru- Thiruvanathapuram.

“A High Speed Rail Network (railway lingo for bullet trains) takes almost half a decade to go from the drawing board to the first pile on the ground. It could be a decade before work starts on any of these projects. Preparing to have some kind of homegrown expertise to build such coaches, rather than just looking to import, is a good move,” said a railway official.

The MagLev, currently in operation in China and Japan, is a much more expensive proposition though speeds touched by these trains are in excess of what some bullet trains can achieve. Recently, Japan managed to run a MagLev train at over 600 kmph during a test, which is a world record for a train’s speed.

India to adopt Magnetic Levitation (MagLev) Technology for High Speed Rail Systems

India to adopt Magnetic Levitation (MagLev) Technology for High Speed Rail Systems

New Delhi:  India has taken the first step towards running a truly high speed train by opting for magnetic levitation (MagLev) technology under which the screech of the wheel hitting the track is obviated as the train floats at high speeds a few inches over the track.

Thus India will avoid emulating Chile and some other countries that have been running refurbished versions at higher than currently prevailing speeds on the same track.

Rather, the country is fashioning a new game altogether, said a Railway officer specialising in design. Running on dedicated tracks, the trains will come in complete sets: there will be engine cabs at both ends and non-detachable coaches in the middle. This will eliminate the swaying motion Indian travellers are accustomed to.

The trains will have under carriages placed in a way that one axle and two wheels come under one coach and the rest under the next one, thus guaranteeing rapid fire acceleration.

The snub-nosed engines, super shiny outer hull and windows merged with the coach body are some of the features that will cut air resistance, the Railway official said. With cars to be allowed right next to the platform, passengers can park in front of the allocated coach.

As the train surges to its top speed, WiFi and mobile phone connections will continue to work seamlessly, for the entire ecosystem is electronics-intensive and microprocessor controlled so much so that wayside signals rushing past the train will be reflected on the locomotive’s control panel.
