All-Union Scientific and Research, Planning and Design Technological Institute on Electric Locomotives Building

The Research and Development Institute of Electric Locomotive Engineering (ElNII) was created in 1958 in pursuance of two Government Resolutions "Of Fifteen-Year Master Railway Electrification Plan for the Period of 1956-1971" (1956) and "Of Actions for Insurance of Manufacture of Main-Line Electric Locomotives for Railway Transports" (1958).

The task of VElNII was to perform research and development works and based on the obtained results to creation innovative types of electric locomotives conforming to the conditions and requirements of operation on railways.
