Metros are most feasible in high-density congested cities, especially in a city such as Delhi, which is already densely packed with 14 million and growing exponentially by the year. Remember, it's early days yet for the metro system, and the country's proseprity is on the rise, making the potential for realizing its optimum ridership more possible. And yes, alternate forms of transportation must be explored like CNG-run double-decker buses and even electric buses weith solar-cell roofs to augment the bank of batteries on dedicated priority lanes, like HOV lanes in the US. On the other hand, could the billions spent on the Metro be more usefully utilized on schools, housing and healthcare facilities?
