Hyderabad: Hyderabad Metro Rail Limited on Monday commenced a trial run on corridor II from Jubilee Bus Station (JBS) to Mahatma Gandhi Bus Station (MGBS).
The long awaited corridor would pass through the core city connecting nine Metro stations: JBS-Parade Grounds, Secunderabad West, Gandhi Hospital, Musheerabad, RTC X Road, Chikkadpally, Narayanaguda, Sultan Bazar and MGBS covering 11 kms.
A team of technical experts and engineers led by HMRL manager N.V.S. Reddy. and L&T MRHL MD K.V.B. Reddy travelled by Metro on this corridor and observed various technical and safety parameters and performance of the train during the trial run.
It would take 16 minutes to cover this corridor from JBS to MGBS, as against 45 minutes by road, said N.V.S. Reddy.
N.V. S. Reddy said that the data and other inputs in these tests will be sent online to M/s Thales in Canada, which is supplying communication-based train control (CBTC) technology.
Signalling and train control software will be fine-tuned based on these inputs for safe operation of metro trains in automatic mode with CBTC technology.
After receipt of satisfactory performance and safety certification from Thales, the internal safety assessor (ISA) M/s. Halcrow and other Indian and international organisations, the commissioner of Metro rail safety (CMRS) will be invited for the final safety clearance of the corridor. After CMRS safety certification, the corridor will be thrown open for passenger operations.
During a series of trial runs to be carried out in the next few weeks, a large number of technical specifications, performance criteria and safety standards will be tested under the following broad categories: signalling tests and safe train separation tests; brake test by the signalling and train control system; overhead electric (OHE) - rolling stock (metro coaches) current collection tests; passenger information announcements and display tests; dummy passenger evacuation tests and degraded mode operation tests.
