Coinciding with first anniversary of Hyderabad metro rail project, L&T has commenced trial runs between the Ameerpet and the IT hub of Hitec City stretch of Metro corridor-III.
A team of technical experts and engineers led by HMRL MD NVS Reddy and L&TMRHL MD KVB Reddy travelled on this stretch and observed various critical parameters and performanceduring the trial run.
The stretch between Ameerpet and Hitec city is of 10 km with 8 stations. Overcoming several technical challenges due to sharp curvatures and gradients and innumerable Court cases against acquisition of the affected properties, with the completion of this stretch, will provide the eagerly waited Metro Rail access to the Hitec city area.
Twin single line method
Since the train reversal facility beyond Hitec city station will take a few more months for completion, trains would be run in “twin single line method,” wherein the the train operations will function on double line railway track as two separate single lines. Trains are operated in both up and down directions on the same line as if these are two independent single lines. This method, which is used by many railways in the world including Indian Railways under some special circumstances, will be followed till train reversal facility beyond Hitec city Metro station is completed.
Both conventional railway signalling systems and the highly sophisticated Communication Based Train Control (CBTC) system of Hyderabad Metro permit this type of twin single line train operations.
