Hyderabad: Trial Runs in Metro corridor-II JBS-MGBS have been commenced here on Monday. A team of technical experts and engineers led by HMRL MD Mr. NVS Reddy and L&T Metro Rail (Hyderabad) Limited MD Mr. KVB Reddy traveled by Metro train on this corridor and observed various technical and safety parameters and performance of the train during the trial run.
With a length of 11 km, the corridor has 9 stations: JBS-Parade Grounds; Secunderabad West, Gandhi Hospital, Musheerabad, RTC X Road, Chikkadpally, Narayanaguda, Sultan Bazar, and MGBS. It would take 16 minutes to cover this corridor from JBS to MGBS, as against 45 minutes by road, said Mr. NVS Reddy.
During the trial runs which would 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:
- Signaling tests and safe train separation tests;
- Brake test by the signaling and train control system;
- OHE-Rolling stock (Metro coaches) current collection tests;
- Passenger information announcements and display tests;
- Dummy passenger evacuation tests;
- Degraded mode operation tests, etc.
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 and the 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 related Indian and international organisations, the Commissioner of Metro Rail Safety (CMRS) will be invited for final safety clearance of the corridor. After CMRS safety certification, the corridor will be thrown open for passenger operations.
Both the MDs complimented the dedicated teams of engineers from L&T, HMRL and other organisations who worked relentlessly and made the corridor ready for trial runs.
