If the early comments on the Great Debate are anything to go by, it seems there is still a lot of goodwill towards Elattuvalapil Sreedharan.

The man behind the Delhi metro, seen as one of India’s most successful infrastructure projects, resigned on Sunday after part of a rail bridge in the capital collapsed and killed six people.

Sreedharan had enjoyed a towering profile as a civil engineer who got things done — and quickly. In the words of his spokesman, Sreedharan “can walk into the prime minister’s office. He has a reputation that he carries.”

Business students from as far away as Harvard have studied the metro’s success.

In contrast to the delays, cost-overruns and red tape that have plagued projects for decades, the subway’s first phase finished on budget and nearly three years ahead of schedule, with 99.5 percent of trains running on time.
