The Mumbai Metropolitan Region Development Authority (MMRDA) has unloaded first lot of Metro rails for the Dahisar (East) to Andheri East) Metro-7 corridor near National Park station. The Head Hardened HH1080 grade rails Imported from Japan were transported from Wadala yard using 70 ft trailer to the site. Thereafter, using 50-ton mobile crane, the rail bundles (Each consisting 3 rails) were lifted and unloaded on the Viaduct. The Metro team was able to accomplish the task within the stipulated time. The unloading of rails for the present stretch of Viaduct will continue for another 3-4 days.
