What the job involves
Railway Group D posts cover the entry-level technical and support roles that keep Indian Railways running day to day: track maintainer, helper and assistant posts across mechanical, electrical, engineering and signalling departments. It does not require an engineering degree; most posts ask for class 10 pass or an ITI certificate in a relevant trade, which makes it one of the more accessible routes into a central government job with the scale and stability that Indian Railways, one of the country’s largest employers, offers.
How to get there
The Railway Recruitment Boards (RRBs) conduct Group D recruitment through a single centralised exam, commonly referred to by its recruitment notification name (CEN) for Level 1 posts. This is separate from RRB NTPC, which recruits for non-technical popular categories such as clerk, goods guard and commercial apprentice at a higher qualification level (class 12 or graduate, depending on the post).
Both are conducted by the RRB system rather than a single national exam covering every railway post, so a candidate aiming at railway employment broadly should track both notification cycles rather than one.
Qualification you need
Group D posts generally require class 10 pass, and specific technical posts may additionally require an ITI certificate in the relevant trade. RRB NTPC posts require class 12 pass or a graduate degree depending on the specific post applied for. The exact requirement for each post is set out post by post in the relevant notification.
A realistic timeline
Group D recruitment runs as a computer based test followed by a Physical Efficiency Test and document verification; there is no interview. RRB NTPC runs two stages of computer based tests followed by document verification, with a typing test for specific posts. Both are large scale, infrequent recruitment cycles relative to something like SSC, so preparation timelines should account for a longer wait between notification cycles than the SSC family of exams typically has.
