the Union Cabinet clearing 100 per cent electrification of all the broad-gauge (BG) routes of the Indian Railways by 2021-22, the national transporter is working on a master plan to convert its entire fleet of about 5,500 diesel locomotives into electric ones at less than half the cost of refurbishment of diesel engines.
"The Railways has now developed an indigenous technology to convert our diesel locomotives to electric ones now they introduced 2 invention or restoration named as WAG11 and WAGC3
WAGC3 locomotive was been modified from a diesel locomotive (WDG3A) manufactured...

by ALco and is been converted to an electric locomotive by the use of pure Indian Technology under the Make in India initiative. It is been successfully tested locomotive that works on the electric traction of 25 kV 50 Hz AC.
This locomotive is been confused to be a dual mode (that can work on both electric and diesel traction) locomotive but that is not true. According to the statement by the Ministry of Railways, it is a pure electric locomotive and also the name suggests the same. It is a twin electric freight locomotive consisting of two locomotives having output power rating of 5,000 hp making it a resultant locomotive having 10,000 hp power.
This same process for WAG11 they change the old WDG4 into WAP 7 shell both of them consists more HP power to handling freight trains this are in Alstom model engines made in India this are new tested locomotives for IR from this two invention which one is more attractive by you
