Indigenous substitution of import ed materials on Indian Railways

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.
