About SCRA

Special Class Railway Apprentices' (SCRA) refers to a handful of candidates that are selected by the Union Public Service Commission India, after a rigorous selection process, to the undergraduate program in Mechanical Engineering at the Indian Railways Institute of Mechanical and Electrical Engineering. This programme was started in 1927 and is one of the oldest in India.
