Rolling Stock
Alstom signed its first metro rolling stock contract in India for supplying 168 cars and 16 additional metro cars to Chennai Metro. Alstom will supply Chennai metro's public operator with 42 train-sets composed of four cars each. Each coach costs CMRL Rs. 9 crore. The stainless steel trains will feature air-conditioned interiors and electrically operated automatic sliding doors, offering comfort and easy access to passengers. They will be equipped with a regenerative braking system ensuring significant energy savings. The cars will operate on 25 KV AC through an overhead catenary system at speeds of up to 80 km/h. The first coach from Alstom Transport for the Chennai Metro Rail project is expected to be launched from the Sri City Special Economic Zone by April 2013. Alstom Transport has set up a metro car manufacturing unit at Sri City SEZ at Tada, about 90 km from Chennai.
The initial frequency will be every 4.5 minutes in peak hours and every 15 minutes in lean hours, when the Metro Rail is inaugurated. CMRL is planning to increase the frequency to one train every 2.5 minutes once footfalls reach 600,000 passengers a day. The train will have an average speed of 34 km per hour and will halt at every station for about 30 seconds.
Each 4-car train will have a carrying capacity of 1,276 people and each 6-car train can carry 1,580 people. A single trip in a 4-car train is equivalent to a ride in 16 buses, 300 cars, and 600 two-wheelers. By 2016, the number of passengers using the service during peak hours is expected to be around 24,968 in corridor I and 24,324 in corridor II.

Famous quotes containing the words rolling and/or stock:
“... in the cities there are thousands of rolling stones like me. We are all alike; we have no ties, we know nobody, we own nothing. When one of us dies, they scarcely know where to bury him.... We have no house, no place, no people of our own. We live in the streets, in the parks, in the theatres. We sit in restaurants and concert halls and look about at the hundreds of our own kind and shudder.”
—Willa Cather (1873–1947)
“I consider that a man’s brain originally is like a little empty attic, and you have to stock it with such furniture as you choose.”
—Sir Arthur Conan Doyle (1859–1930)
