How to prepare

  • Use a recent colour passport photograph with a white or light background, taken in a professional studio.

  • Differs from RRB NTPC CEN 05/2024, which requires 20-50 KiB for this same 320 x 240 px frame - do not reuse NTPC's KB range for Group D.
  • PwBD candidates using a scribe must additionally upload the scribe's passport-size photograph on a plain white background, JPEG, 50-100 KiB - the same rules as this candidate photo.

  • Use this only if requesting the free sleeper-class rail-travel pass as an SC/ST candidate; it is not a universal upload for every Group D applicant.
  • Differs from RRB NTPC CEN 05/2024, which requires this same certificate as a JPG/JPEG scan (50-100 KiB), not a PDF - do not reuse NTPC's format for Group D.

Date notes

  • Official CEN 08/2024 header table (PDF page 2): publication 22.01.2025; online registration opened 23.01.2025 00:00 Hrs.
  • Corrigendum-1 to CEN 08/2024 (dated 19.02.2025) revised the original closing date from 22.02.2025 to 01.03.2025 (23:59 Hrs), the late-fee-payment cutoff from 24.02.2025 to 03.03.2025, and the modification/correction window from 25.02.2025-06.03.2025 to 04.03.2025-13.03.2025. This preset uses the corrigendum's revised dates, not the dates originally printed in the CEN header table.
  • As of 2026-07-10, RRB Secunderabad's own CEN 08/2024 notice archive shows the process at the post-CBT Physical Efficiency Test (PET) shortlist stage (a PET-shortlist PDF dated July 2026 is the latest posted item). This page is a source-backed, closed-window upload-rule reference, not an active application page.
  • A separate DV-stage photo/signature re-upload step is referenced in the CEN (PDF page 30, section 18(b)) via the portal oirms-ir.gov.in/rrbdv; that portal's own size/dimension rules were not located or verified in this pass and should not be assumed to match the application-stage numbers below.
  • This page only prepares upload files; it is not the official RRB application portal.

Submission-readiness check

RRB Group D applicants usually need more than a compressed file. Use this page to prepare the source-backed files, then finish the remaining steps on the official portal.

Still on the official portal

SarkariDoc cannot submit the form, capture live portal photos, make payments, or edit RRB online application (rrbapply.gov.in). Keep the official portal open for final submission.

  • Corrigendum-1 to CEN 08/2024 (dated 19.02.2025) revises the closing date for online submission to 01.03.2025 (23:59 Hrs) and the modification window to 04.03.2025-13.03.2025. Full-text checked: it contains no changes to the photograph, signature or SC/ST certificate specifications.
  • This PDF, dated July 2026 and the latest item in RRB Secunderabad's CEN 08/2024 notice archive, confirms the process is at the post-CBT PET-shortlist stage as of verification, well past the application stage.

About this exam

RRB Group D (Level-1) CEN 08/2024 recruits for various Level-1 posts across Indian Railways. Online applications ran from 23 January 2025 to 1 March 2025 (extended by Corrigendum-1), and as of 2026-07-10 the process is at the post-CBT Physical Efficiency Test (PET) shortlist stage, per RRB Secunderabad's own CEN 08/2024 notice archive. The CEN's 'ONLINE Mandatory Scanned Documents' block requires a photograph and a signature upload, plus an optional SC/ST community certificate PDF for candidates requesting a free rail-travel pass and a scribe's photograph for PwBD candidates who use a scribe. SarkariDoc prepares only these upload files. It does not and cannot prepare the Left Thumb Impression and self-declaration paragraph handwritten live at the CBT venue in front of an invigilator, or the live signature and facial-feature matching performed at CBT, PET, Document Verification and Medical stages - those are on-site, live-capture events, not file uploads.

RRB Group D (Level-1) CEN 08/2024 candidates - including those now at the PET-shortlist stage - who need the photograph, signature or SC/ST certificate file to match the official CEN's scanned-document rules, and PwBD candidates who need to prepare a scribe's photograph on the same rules as the candidate photo.
