A team from the Research Designs and Standards Organization (RDSO) in Lucknow has begun intensive trials on the Kochi Metro trains to ensure passenger comfort and safety. RDSO began their trials on Monday after fitting transducers and sensors on various components of the trial run coaches and also carried out a few runs along the 9km Muttom-Palarivattom stretch to assess various parameters. The team will initially operate empty trains and later simulate the ‘crush load’ – the maximum capacity of the trains which is 900 people – by filling the coaches with sand bags.
RDSO will also assess breaking distance at different speeds as well as the efficiency of third traction from which power is sourced will be measured. A whole range of other mandatory oscillation trials too will be done. Towards the end of the trials they will also be testing whether the coaches can tow another stranded coach to a station or yard from the track.
The trials will continue till October 5 and RDSO’s report is expected in a month. It will be submitted to both the Commissioner for Railway Safety (CRS) and Railway Board. After verifying the report, the CRS is expected to do a bird’s eye inspection of the metro system and grant permission to commission the metro. The Electrical Inspector General to the Government of India had inspected the third traction laid between the track and other electrical components and accorded his nod to charge the viaduct up to Palarivattom. Integrated trials are expected by November, once communication-based train control systems are in place.
As per latest schedule, the 12-km-long Aluva-Palarivattom stretch will be ready for commissioning by April, while the 6-km-long Palarivattom-Maharaja’s College Ground corridor will be ready by June.
