Another push in Make in India campaign as the government informed that maiden consignment of six metro coaches made in Bombardier facility in Savli, Vadodara were shipped to Australian government from Mumbai port.
The production and exportation of metro coaches is a boost in “Make in India” campaign which aims at turning the country into a global manufacturing destination. The sustained indigenization initiatives of manufacturing railway wagons within India had driven India to such a landmark.
Being the first of its kind export, India creates history in the manufacturing sector. As a part...

of the deal, in the coming 2 and a half year 450 such commuter cars with bogies will be exported to Australia. The project costing a total of 2.7 billion USD for the Canadian firm, Bombardier Transportation will be executed in their Vadodara facility. The Savli site has been developed for the export oriented activities.
“The maiden consignment of six metro coaches built in Baroda for export to the Australian government were shipped from Mumbai Port as Mumbai Port holds supremacy in handling of over-sized precious cargo ” a statement from Ministry of Shipping said.
The coaches are 75 feet long and weigh 46 tonnes each, requiring a superior and highly specialized loading operation with a high degree of precision, it added.
“The entire stevedoring operation (loading into ship) of these prestigious over-sized metro coaches has been done in-house by Mumbai Port Trust unlike any other port in India where private operators carry out such operations,” the statement said.
Some of the facts about indigenous railway wagons that will make every Indian proud:
■ India will be exporting 521 bogie frames to Brazil for Sao Paulo monorail.
■ Recently, Delhi metro achieved the landmark of producing 90% of its wagons locally. Of the 1,234 coaches in Phase I and II, only a mere 36 were from Germany and 64 were from Korea. In the III phase, out of 846 coaches that have been ordered, only 120 are from Korea and rest are being manufactured in India.
■ Three Metro coach manufacturing units have already been established in India. While Bombardier Transportation has a unit in Savli (Gujarat), state-owned Bharat Earth Movers Limited (BEML) has a unit in Bengaluru and Alstom has established a new facility at Sricity near Chennai creating hundreds of jobs.
■ Kochi Metro Rail (KMRL) recently received the first set of Made in India coaches five months ahead of schedule from the French company Alstom Transport.
■ The capital costs of Metro coaches in India are substantially lower than the rest of the world. For instance, while the capital cost of a coach is around Rs 8.94 crore in India, the cost in Vancouver is Rs 16.08 crore and in San Francisco is Rs 15.13 crore
■ In the coming 5 years there will be a demand of 2000 metro trains in India will prove to be a boon for India’s manufacturing sector.

What is Aerodynamics ?
Ans: Aerodynamics, from Greek ἀήρ aer (air) + δυναμική (dynamics), is a branch of Fluid dynamics concerned with studying the motion of air, particularly when it interacts with a solid object, such as an airplane wing. Aerodynamics is a sub-field of fluid dynamics and gas dynamics, and many aspects of aerodynamics theory are common to these fields. The term aerodynamics is often used synonymously with gas dynamics, with the difference being that "gas dynamics" applies to the study of the motion of all gases, not limited to air.Formal aerodynamics study in the modern sense began in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag have been recorded much earlier. Most of the early efforts in aerodynamics worked towards achieving heavier-than-air flight, which was first demonstrated by Wilbur and Orville Wright in 1903. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simulations has formed the scientific basis for ongoing developments in heavier-than-air flight and a number of other technologies. Recent work in aerodynamics has focused on issues related to compressible flow, turbulence, and boundary layers, and has become increasingly computational in nature.

Applicable Fields of Aerodynamics:
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Aerodynamics is important in a number of applications other than aerospace engineering. It is a significant factor in any type of vehicle design, including automobiles. It is important in the prediction of forces and moments in sailing. It is used in the design of mechanical components such as hard drive heads. Structural engineers also use aerodynamics, and particularly aeroelasticity, to calculate wind loads in the design of large buildings and bridges. Urban aerodynamics seeks to help town planners and designers improve comfort in outdoor spaces, create urban microclimates and reduce the effects of urban pollution. The field of environmental aerodynamics studies the ways atmospheric circulation and flight mechanics affect ecosystems. The aerodynamics of internal passages is important in heating/ventilation, gas piping, and in automotive engines where detailed flow patterns strongly affect the performance of the engine. People who do wind turbine design use aerodynamics. A few aerodynamic equations are used as part of numerical weather prediction.

With final test runs almost complete, Mumbai Monorail's first phase will take on commuters before the festive season, say MMRDA officials.
.
Slowly but steadily, the Mumbai Monorail is getting ready to open its doors to citizens before Diwali. Trial run between Chembur and Wadala would be completed by mid-July.

the first trial run the MMRDA approached Indian Railway of testing and certify the safety measures which was declined by Commissioner of Railway Safety (CRS) stating that it does not have capacity to certify the monorail, as they have no expertise or knowledge in running monorail. Then MMRDA appointed a Singapore-based SMART agency to monitor the testing process which is undergoing now.
