Yeah, 2 Railway officials told me this on sunday at Hadapsar. After putting up of the poles and wires in the whole PUNE DD strech, they need to set up power grid which needs to supply power on this line. It is yet to be decided so as to where will the power grid set up to give power for the electric trains, after which there will be few tests, and then the trains will be allowed to pass here. So they feel minimum 2 years is still required.
