sir,
in 263 KM, 136 KM line is double,
in which 73 KM line is electrified(PUNE to DDAP)..
remaining 30 KM line, the working of electrification is under progress (DDAP-DD-BGVN). the electric pole has been standed, only wiring is remaining.
33...
more... KM line is already double (MO-SUR).
so, 73+30+36=136.
rest of 127KM(=263-136) line is single, first it will doubled then electrified.
the work of doubling is under progress.
