Chennai division of Southern Railway, has, today, successfully completed the erection of 17 precast R.C.C (Reinforced Concrete Cement) boxes (9 nos + 8 nos) of size 5 metres x 2.75 metres on Fast lines (UP and DN) in Veppampattu Station in Chennai – Arakkonam section at km 32/9-11 for the pedestrian subway. The station consists of four lines, three platforms and presently there is no Foot Over Bridge or subway. Hence the work has been taken up on priority.
The work has been successfully completed despite the space constraints at the site due to densely populated area. The work area available for leveraging the machines was limited and machines could not operate without infringing the remaining track portion and working was possible from only one direction. The work has been planned and taken up in a mega block spread over two weekends from Saturday Night till Sunday Morning (two lines on each weekend block) to minimise the repercussion to train services,thus ensuring that there is least disruption to regular train services.
The first portion beneath the Slow lines (UP and DN) of 8 RCC precast box segments have been completed by the division within the sanctioned block time on 18th and 19th May 2019, and the second portion beneath the fast lines (UP and DN) of 9 RCC precast box segments have been completed within the sanctioned 12 hours line and power block from May 25th night to May 26th (today) morning. Total 17 box segments underneath the tracks have been completed during the mega block. The planning and coordination of various departments like Engineering, Traction, Signal and Telecommunication, Operating and RPF, made the completion of this work within the stipulated time, possible. In the coming days some more ancillary works will be done to fully complete this subway which is being constructed for the use of passengers crossing the tracks at Veppampattu Station. Hence tresspassing by the public will be prevented on completion of this work.
Utilising this block period, vital track maintenance works and other developmental works were carried out in the section. 5.9 kms track has been packed in the section using the track tie tamping machine and other track maintenance works like through Rail Renewal for Points and Crossing including track welding work has been done in the section. Also, earth work for extension of platform/provision of platform at Tiruninravur Railway Station was done during the block period.
