Chennai: CMRL officials have started installation of overhead power cables on elevated lines as track laying work is nearing completion on the elevated Little Mount-Alandur stretch of the Washermenpet -airport corridor.
Trains use power drawn from these lines to run. After cables are installed, electrical substations and equipment will be installed and trials conducted in the coming months. The stretch, part of the Little Mount-Alandur-airport elevated line, is the next elevated line scheduled to be commissioned.
The line was supposed to be opened in mid-2014. But it got delayed because contracts failed and metro rail had to call for fresh tenders and award the work to new contractors.
As viaducts and tracks are ready between Little Mount and Alandur, metro rail has started overhead power cable installation. The line will pass one level lower than the Koyambedu-Alandur line at Alandur station.
“The work is going ahead at a good pace though behind schedule. We hope to complete the cable and unfinished work on the viaduct and the tracks in the next few months. A good percentage of the construction work on the elevated viaduct has been completed till the airport. Station work is also going on,” said a metro rail official. The roof of the stations over the platforms has been fixed at Little Mount and Guindy.
Sources said it would take a year for the Little Mount-Alandur-Airport elevated lines to be ready. “It will take another few months for the trials to be completed,” said an official.
Though the underground line along Anna Salai is stuck after the contract with Gammon-Mosmetrostroy JV was terminated, metro rail is readying the Koyambedu-Shenoy Nagar underground line where tunnel boring was completed a few months ago. “Track laying has started along the stretch inside the tunnels,” he added.
