For the second successive day, L&T Metro Rail Hyderabad (L&TMRH) ran the metro train for a 2-km stretch from the Nagole depot till the Survey of India as excited onlookers, local people and scores of mediapersons tried to capture the moment.
Metro rail authorities informed on Friday that several tests would be conducted on the rolling stock or the trains, both in static and running conditions, in the depot and viaduct for the next six months. And once these tests are done, inspection will be carried out for necessary safety approval certificates.
Officials said only ‘test runs’ would be conducted thoroughly over the next few months on the viaduct, which is the first construction stage of the project between Nagole-Mettuguda - Corridor one: Nagole to Shilparamam-Raidurg.
‘Trial runs’ will commence much later. In this, all the seven trains will be run as per the time table and the schedule during commercial operations all through the day, for 60 days (‘burning period’), during which the RAMS (Reliability, Availability, Maintainability and Safety) target will be monitored and the entire system will be stabilised, they explained. When contacted, Hyderabad Metro Rail (HMR) MD N.V.S. Reddy explained that several stability and dynamic tests are under way to test each component’s ‘behaviour’ when the train is on the run. Checks will be made on the communication systems, track, power traction, signalling, breaking, electro-magnetic capability, doors movement, cameras, oscillations and so on. For now, Hyundai-Rotem (Korean train makers) engineers and others are participating in the test run and soon engineers from HMR and other vendors will join, he added.
