Indigenous substitution of import ed materials on Indian Railways

Abstract

THE psychology of import substitution is based on the concept of dispensing with as much import as poss- ible by providing alternative indigenous resources. In a developing country like India, it is essential to stress on research , development and trials through different research laboratories/Institutes by suggesting substitutes of imported materials for the avoidance of use or conservation of the imported materials in our country, particularly in the emergency which has high-lighted the necessity for intensifying efforts in this direction.
