Bangalore Metro: Test run for Green line train to begin in Peenya depot

There is some hope for North Bangaloreans, as the Bangalore Metro Rail Corporation (BMRC) gears up for testing the trains in its northern depot. The BMRC is beginning to charge the tracks in Peenya depot and test the three rakes on these tracks.

"The test track will be charged on Wednesday and trial runs will be commenced shortly," said a official from BMRC, in charge of northern corridor. However, rumours did rounds till Tuesday morning that the chief minister has announced the trial runs between Rajajinagar and Peenya from Wednesday.

"The report is wrong. The trial run is in the depot and not on the main line. The trains are tested in the test track in depot first. The train systems and traction power systems will undergo elaborate tests for the next three months," N Sivasailam, managing director, BMRC, said clearing all rumours.

There are three rakes supplied by the BEML from their Bangalore factory near Baiyappanahalli, for the tests and trials, until now. These trains are bordered with green bands, as a part of the colour code of the corridor. The north-south corridor is called the Green line.

The Peenya depot has the longest testing track of 1.2 km, more than what the Baiyappanahlli track has. Not just trial runs, even static tests will be performed once the tracks are charged. The static tests include opening of the doors and electrical connections working in tandem inside the coaches. The motion tests will include the running of the trains, speed and distance brake tests.

The line will be charged up by 750 dc power, drawn from the Peenya sub station. The engineers will charge the line and keep monitoring whether the line is able to take the load and if that cause any other power disruptions in the depot. These tests will take some time.

This is one step towards the commissioning of the northern corridor, running between Malleswaram and Peenya, called the Reach 3. There are 9 stations-Malleswaram, Srirampura, Kuvempu road, Rajajinagar, Mahalakshmi, Soap Factory, Yesvanthpur, Yesvanthpur Industry and Peenya.

However, the litigations pertaining to the Malleswaram station, Srirampura railway over bridge and Soap Factory stations, could delay the commissioning of the line. Earlier, the BMRC expected to start the commercial operations in the northern line by end of 2012.

The South Western railway alone has dragged the BMRC to two litigations regarding the station construction on Sampige road, adjacent to the Mantri Mall and a clearance to be given for a span construction over the Srirampuram rail line. The soap factory litigation has held work at this place for over 10 months and BMRC has kept saying that they would try to finish the work as fast as possible.

A person residing in the land where the station was to be built had petitioned against BMRC over the land acquisition, which was ultimately dismissed by the apex court in May.
