The adoption of faster modes of transport has changed profoundly the spatial organisation of cities. The increase in average speed of a city's transport system calls for more space. The result is urban sprawl and reduced density. Dominant transport modes are, therefore, the determinants of urban structures. The increase in distance covered due to increased speed of travel and urban sprawl leads to an increase in energy consumption.

The Indian Railways (IR) has set up its first wind farm at Integral Coach Factory, Tamil Nadu in its efforts to use renewable energy. It has also committed itself to having all its buildings constructed after 2008 to comply with the Energy Conservation Building Code. A look at IR’s commitment to green energy.

Mumbai Metro, Mumbai’s first Mass Rapid Transit System, will cross Andheri’s JOG flyover on Western Express Highway at a height of 22m by a Cable Stayed Bridge for its first line – the VAG corridor. Extended Pier caps have been designed to avoid Piers at the centre of any traffic junction to allow larger spans – a first in the world for Metro Projects. 16 trains will be put in service with a four coach unit carrying 1500 passengers, reducing the travel time from 90 to 21 minutes.
