In 2015, a consortium consisting of Navrood company, Pasiloo Consulting Engineers, and Iran Khak Consultants, led by Navrood, was awarded a contract for the engineering, procurement, and construction of Sistan – Isfahan double tracking railway project, in order to increase the capacity of the existing track. The new track will be constructed on the vicinity of the existing one, and is de-signed to increase the load bear-ing capacity from 25 tons of axle loads to 30 tons, and to sustain a track speed of 160 km/h.
