They had a chance, entire area was cordoned off to construct an Underground Metro Station and a new Bus Terminal at Shivaji Nagar. Maha Metro overseeing entire construction. They could've expanded Shivaji Nagar Station using that opportunity but they didn't now Shivaji Nagar Metro Station and Bus Terminal are almost complete, CR won't get a chance at expansion anyhow. Too much high priority Buildings surrounding that area, NABARD, Sancheti Hospital, Bank Of Maharashtra Head Office everything is there.
