Accomplishment of Milestone 'G6' will be a pre-requisite for issue of the Performance Certificate. Not applicable. During the Contract period, which ends after the completion of 24 months of DLP period from Last Trainset commissioning, even the first trainset will not run for 3 years. Hence, no intermediate over hauling is required during the contract period. We have therefore not quoted for any overhauling spares. No price of withdrawal is indicated in the price bid.
