Every year, the Indian Railways announces thousands of job openings for graduates, 10+2 students, and matriculants. The Railways receives crores of application forms in response to vacancies. Railway Recruitment is handled by Railway Recruitment Boards (RRBs) and Railway Recruitment Cells (RRCs).

Moreover, Railway Recruitment Boards have implemented online application submissions. Candidates can now fill out and apply online. Previously, candidates had to obtain the application form from the corresponding RRBs, by mail, or through Employment News or newspapers. Tests were conducted on computers instead of pen and paper on the railways. Admit cards for Railway Recruitment Board exams are distributed online.
