==History==
To enforce standardization and co-ordination between various railway systems in British India, the Indian Railway Conference Association (IRCA) was set up in 1902. It was followed by the establishment of the Central Standards Office (CSO) in 1930, for preparation of designs, standards and specifications. However, till India's independence in 1947, most of the designs and manufacture of railway equipment was entrusted to foreign consultants. After independence, a new organisation called Railway Testing and Research Centre (RTRC) was set up in 1952 at Lucknow, for undertaking the intensive investigation of railway problems, providing basic criteria and new concepts for design purposes, for testing prototypes and generally assisting in finding solutions for specific problems. In 1957, the Central Standards Office (CSO) and the Railway Testing and Research Centre (RTRC) were integrated into a single unit named Research Designs and Standards Organisation (RDSO) under the Ministry of Railways with its headquarters at Manak Nagar, [[Lucknow]].<ref name=r1/> The status of RDSO was changed from an "Attached Office" to a "Zonal Railway" on 1 January 2003, to give it greater flexibility and a boost to the research and development activities.<ref name=salient>{{cite web

The Research Designs & Standards Organisation (RDSO) is the research and development and railway technical specification development organisation under the Ministry of Railways of the Government of India, which functions as a technical adviser and consultant to the Railway Board, the Zonal Railways, the Railway Production Units, RITES, RailTel and Ircon International in respect of design and standardization of railway equipment and problems related to railway construction, operations and maintenance.[1][2][3]

History[edit | edit source]

To enforce standardization and coordination between various railway systems in British India, the Indian Railway Conference Association (IRCA) was set up in 1902. It was followed by the establishment of the Central Standards Office (CSO) in 1930, for the preparation of designs, standards, and specifications. However, till India's independence in 1947, most of the design and manufacture of railway equipment was entrusted to foreign consultants. After independence, a new organisation called Railway Testing and Research Centre (RTRC) was set up in 1952 at Lucknow, for undertaking the intensive investigation of railway problems, providing basic criteria and new concepts for design purposes, for testing prototypes and generally assisting in finding solutions for specific problems. In 1957, the Central Standards Office (CSO) and the Railway Testing and Research Centre (RTRC) were integrated into a single unit named Research Designs and Standards Organisation (RDSO) under the Ministry of Railways with its headquarters at Manak Nagar, Lucknow.[1] The status of RDSO was changed from an "Attached Office" to a "Zonal Railway" on 1 January 2003, to give it greater flexibility and a boost to the research and development activities.[4][5]

Organisation[edit | edit source]

RDSO is headed by the Director-General, who is equivalent to the general manager of a Zonal Railway. The present Director General is Sanjeev Bhutani [6] The Director-General is assisted by an Additional Director General and 23 Sr. Executive Directors and Executive Directors, who are in charge of the 27 directorates: Bridges and Structures, the Centre for Advanced Maintenance Technology (CAMTECH), Carriage, Geotechnical Engineering, Testing, Track Design, Medical, EMU & Power Supply, Engine Development, Finance & Accounts, Telecommunication, Quality Assurance, Personnel, Works, Psycho-Technical, Research, Signal, Wagon Design, Electric Locomotive, Stores, Track Machines & Monitoring, Traction Installation, Energy Management, Traffic, Metallurgical & Chemical, Motive Power and Library & Publications. All the directorates except Defence Research are located in Lucknow.
