Metro rail lines in India are composed of both standard gauge and broad gauge. Projects like the Delhi Metro used broad gauge for their earliest lines but most new projects in India are on standard gauge as rolling stock imported from Europe is on Standard Gauge. One exception is the Ahmedabad Metro, which will use Broad gauge, as there is more space available inside the coach. In the long term, using Broad gauge may also allow for freight movement of containers from the Indian Railway network on the Metro train network and increased capacity within the train cars. Although Metro supposed to be mass rapid transit system, Indian metro trains are slower than their counterparts in other parts of the world, as they are mostly over ground and have sharp curves. For example, Bangalore metro has a maximum speed of 40.5 km/h on curves with average speed of 30 km/h and Hyderabad Metro will have average speed of 25 km/h.
