CHENNAI: Chennai division of Southern Railway on Sunday erected 17 precast Reinforced Cement Concrete (RCC) boxes beneath the tracks at Veppampattu station in Chennai-Arakkonam section for a pedestrian subway within the line block time. A release said the work was planned and taken up in a mega block spread over two weekends from Saturday night till Sunday morning to minimise disruption to train services.
The first portion beneath the slow lines of eight RCC precast box segments was completed within the sanctioned block time -- May 18 to 19. The second portion beneath the fast lines of nine RCC precast box segments was completed within the sanctioned 12 hours from Saturday to Sunday.
Totally, 17 box segments underneath the tracks have been completed during the mega block. The planning and coordination of various departments made the completion of the work within the stipulated time.
