Dear, first and foremost doubling is not a easy task. In the first phase the work of construction of new bridges are done wherever required. Then the earth work is done with levelling , and is left as it is for one season for it to get harder after rains. Then planing is done with roller pressing etc, then the engineer tests the hardness of the soil over the new bed, then the sleepers are laid, and then rails are laid over it, then ballast work. Then test run is done , then inspection is done , and then final nod is given to run commercially. So, this whole procedure takes around minimum 3-4 years. So, we can't expect doubling in a jiffy. In my opinion, the doubling shall be completed by December 2018.
