Summary:
Railway authorities are digging into the possibilities of an underground fast line from south Mumbai to Thane, aligned with its above-ground local version from Chhatrapati Shivaji Maharaj Terminus (CSMT) to Thane. For the past few months, the Delhi Metro Rail Corporation (DMRC) has been studying the possibility of this route. Yet, some railway officials feel the proposed underground rail would only amount to duplication of the Metro work going hammer and tongs in the metropolitan region. As its extension, the Wadala-GPO Metro rail line has also been announced. Officials working on the proposed CSMT-Thane underground corridor, though, claim its alignment or construction would not disturb the Metro work..
