Electrical Directorate
Electrical Directorate is responsible for design and development of all types of Electric Locomotives including their sub-systems. It also deals with service related technical problems, including standardization, indigenisation of technology/sub-systems through industry and quality control/vendor base of vital items of Electric Locomotive assigned to RDSO by Railway Board. Work also includes evaluation of new technologies and up gradation of product for higher performance, reliability and economies in operation. 
Holding of various types of Electric Locos on IR except WAG-6 A, B, C and WAP-5/WAG9 which were imported in limited numbers with transfer of technology, all locos were designed indigenously at RDSO .With adoption of 3-phase technology and import of WAG-9/WAP-5 class 6000HP, 25KV with TOT from the then M/s.ABB, Switzerland. IR possesses state of art technology in field of Electric Locos. These locos are now being indigenously manufactured at CLW since 1998 and RDSO support this technology and successfully indigenised vital sub-systems through industry, thus bringing down cost of production of these locomotives in India.WAP7 locomotives, indigenously developed is an example of successful example of absorption of technology.
Electrical Directorate is headed by Principal Executive Director Standards Electrical. A team of an Executive Director Standards Electrical and four Directors assist him.
As a Make In India initiative, Electrical Dte has developed the design of WAP7HS, WAG9HC, WAG10 & WAG11 locomotives.
1.   Functions and Role of Directorate
                Electric Traction was introduced in 1925 in the country with 1500 Volt DC system. Later on, the 25 KV AC system was introduced in 1959. With a modest beginning made almost 55 years ago, Electric Locomotives and Traction system have seen remarkable developments in terms of haulage capacity as well as reliability. The Electrical Directorate of RDSO has played a leading role in all these developments.
                The functions of the Electrical Directorate include design and development of different kinds of Electric Locomotives and their equipments keeping pace with the changing technologies and need of the times, guiding the Zonal Railways/ Production Units with regard to problems experienced by them in the maintenance and operation of Electric Locomotives and their equipments, acting as a pivot between Railway Board and Zonal Railways in all technical matters pertaining to the performance of Electric Locomotives over Indian Railways. Therefore, the role of the Electrical Directorate is primarily to design and develop new locomotives and equipments with modern technologies and also to assist the Zonal Railways/Production Units in improving the reliability and act as the Technical Advisor to Railway Board. Directorate also associates with PS&EMU directorate in validating the design & prototype testing of various equipments of  EMU/MEMU.
2. Infrastructure and Capabilities
The office of Electrical Directorate is headed by Principal Executive Director Standards Electrical assisted by officers at the level of Directors (SAG/SG/JA grade). These officers handle the work of different equipments/ their systems used in Electric Locomotives of different designs. Broadly, these have been classified into following groups:
 (i)           System Group dealing with Static Electric Equipments, System Engineering & Auxiliary Machines of Coventional Electrical locomotives 
 (ii)          Three Phase Propulsion System & system Engineering of 3-phase locomotives.
(iii)          Pneumatic System
(iv)         Traction motor
(v)          Mechanical Group for mechanical equipments of Electric Locomotives
3.  Role of Director/ Executive Director of the group:
  (i)        Director/Executive Director is the incharge of each group and is assisted by one senior/junior scale officer and 3 to 4 staff in supervisory category.
 (ii)         Each group handle work related to design, development, performance, vendor development and service engineering for the Railways related to different equipment including state of the art technology for overall improvement of the reliability, safety and availability of the respective equipment and the locomotives.
(iii)          The overall work involves preparation of specification, development of product/locomotive through reputed manufacturers worldwide, prototype inspection & testing, commissioning and monitoring of their performance in field for overall improvement of productivity of the Indian Railways.
(iv)         Various problems experienced and reported by Zonal Railways/Production Units are examined/studied from time to time regarding the performance of locomotives/equipment in field and corrective action/guidance are issued in the form of Modification Sheets, Special Maintenance Instructions, Technical Circulars, and Reports etc.
(v)          Simulation software related to haulage capacity of different kinds of locomotives has been developed and used to simulate and study different conditions of load, gradient, speed etc. Further, a state of art electrical laboratory for testing of various equipment is also being established as an additional facility by the Directorate.
(vi)         Each group help and guide Railways by issuing different documents such as Specifications, Schedule of Technical Requirements (STR), Special Maintenance Instructions (SMIs), Modification Sheets(MS), Reports, Drawings pertaining to various equipment.
