For Bangaloreans the wait for metro train, Namma Metro, is getting longer as the Bengaluru Metro Rail Corporation (BMRCL) is extending the dates of the project completion time to time.    In fact, the delay is costing even the BMRCL itself as it is losing Rs 50 lakh every day that the project is pushed further away, say media reports.    After several missed deadlines, Namma Metro's Reach 1, a small line, opened to the public on October 20 in 2011. As the Metro trains began to finally run in the city, people hoped the BMRCL had learned from experience and would work hard to meet the deadline of June 2012 for the rest of the 42. 3 km of Phase 1.    But it has been just disillusion as nothing seems to have changed, with the deadline for this stretch being first pushed to June 2014 and then to December of the same year.    Traffic snarls at signals on the city roads test the patience of commuters and the city is getting more congested in the meanwhile with more vehicles coming out on its roads. Even the city's pollution levels too are seeing a drastic rise.    As of now of Bengaluru alone accounts for over 40 per cent of the total vehicle population of the state which is reportedly over one crore. Of the 45 lakh vehicles travelling on the city's roads, about 87 per cent are private cars and bikes, jostling for space with over 6,000 BMTC buses and a lakh autorickshaws.    To escape from the time consuming and exhausting traffic snarls, Bangaloreans are looking forward to metro train travel.
