CEN 02/2025 covers two distinct pay levels with separate CBTs. Understanding which grade you appeared for is essential when checking your answer key and cut-off estimates.
| Post | Pay Level | Vacancies | Qualification | Age Limit |
|---|---|---|---|---|

- Grade I Signal (Pay Level-5) candidates and Grade III (Pay Level-2) candidates had separate CBTs with different question papers and separate answer keys.
- When logging into the portal, make sure you are downloading the answer key for the correct Pay Level — Grade I and Grade III are listed separately on RRB websites.
- If you applied for both grades, you need to check and raise objections for each separately before the 27 March deadline.
Follow these 6 steps carefully. The portal at rrb.digialm.com is the centralized access point — it works for all RRB zones. You can also use your regional RRB website directly.
Visit the Official RRB Portal
Go to rrb.digialm.com (centralized) or your regional RRB website (e.g., rrbcdg.gov.in, rrbajmer.gov.in, rrbmumbai.gov.in). On the homepage, look for the link labelled "Viewing of Question Paper, Responses and Keys & Raising of Objections for CEN 02/2025 (Technician Categories)" under Important Links.
Click the CEN 02/2025 Answer Key Link
The link will be labelled "Click Here to View CBT Exam Attempt & Objection Tracker". Clicking it redirects you to the candidate login page for CEN 02/2025. Do not confuse this with ALP (CEN 01/2025) or NTPC links — those are different recruitments.
Log In With Your Credentials
Enter your Registration Number and Date of Birth (DD/MM/YYYY) or your application password. Enter the CAPTCHA code displayed on screen. Click "Login" or "Submit". If you do not remember your Registration Number, check your original application confirmation email or SMS.
View Question Paper, Responses & Answer Key
After login, click "Candidate Response" or "View Answer Key" button on your dashboard. The system will display: (a) the question paper you were shown during exam, (b) your recorded responses for each question, and (c) the official provisional answer key. Cross-check each answer carefully. Take a screenshot or PDF print of your responses for reference.
Raise Objections If Any (Optional)
If you believe any answer in the key is wrong or a question is incorrect, click "Raise Objection" on that question. Select the question, choose your answer as the correct option, and provide a valid technical justification with supporting references. Pay the objection fee of ₹50 per question via the integrated payment gateway. You can raise multiple objections in one session.
Save Your Objection Receipt
After payment, the portal generates a confirmation receipt for each objection raised. Download and save all receipts — you will need them as proof. If your objection is found valid, the ₹50 fee (minus bank charges) will be refunded to your registered bank account after the final answer key is published.
Estimate your CBT score using the official marking scheme: +1 for correct, −1/3 for wrong, 0 for unattempted. Total: 100 questions, 100 marks, 90 minutes.
- Each correct answer: +1 mark
- Each wrong answer: −1/3 mark (negative marking applies)
- Unanswered / skipped questions: 0 marks (no penalty)
- Total CBT: 100 questions × 1 mark = 100 marks maximum
- Duration: 90 minutes (120 minutes for PwBD candidates using scribe)
These are estimated cut-off ranges based on RRB Technician previous year cut-offs, vacancy count (6,238 posts), and difficulty level of the March 2026 CBT. Actual cut-offs will be declared with the result.
| Post | UR / EWS | OBC | SC | ST |
|---|---|---|---|---|
| Technician Grade I Signal (183 vacancies — high competition) | 70–78 | 64–70 | 58–65 | 50–58 |
| Technician Grade III — Fitter/Electrical/Mechanical (high demand trades) | 58–66 | 52–60 | 45–55 | 38–48 |
| Technician Grade III — Other Trades (S&T, Diesel, Workshop, etc.) | 55–63 | 48–56 | 42–50 | 35–44 |
- Grade I Signal has only 183 vacancies against thousands of applicants — competition is extremely high and cut-offs are significantly elevated compared to Grade III.
- Normalisation: Since CBT was held across 4 days in multiple shifts, RRB normalises raw scores before preparing the merit list. The final score may be higher or lower than your raw marks.
- Zone-wise: Cut-offs differ by railway zone (e.g., CR, ER, NR, SR). A score that qualifies in one zone may not clear another with fewer vacancies.
- Category-wise shortlisting: DV shortlisting is done separately for each community (UR/OBC/SC/ST/EWS) within each zone, based on CBT merit.
Both posts have separate CBTs with different subject compositions. Grade I Signal has a more technical syllabus (computers + engineering), while Grade III focuses on mathematics, reasoning, general science, and general awareness.
| Parameter | Grade I Signal (Pay Level-5) | Grade III (Pay Level-2) |
|---|---|---|
| Total Questions | 100 MCQs | 100 MCQs |
| Total Marks | 100 marks | 100 marks |

Raising an objection is straightforward if done correctly. Know what makes a valid objection, how the fee works, and what happens after the window closes.
- The official answer key has the wrong answer for a factual, science, or general knowledge question — with a credible reference (NCERT, standard textbooks, official RRB notifications).
- The question itself is incorrect, ambiguous, or has two equally correct options — you must specify which answer should be awarded marks and why.
- A translation error exists between the English and Hindi/regional language versions of the question that changes the meaning.
- The answer key lists a wrong option for a mathematical or reasoning question — your working must be clearly shown in the justification field.
- Objecting simply because you marked a different answer — if both yours and the official answer are wrong, you still need to prove the official one is incorrect.
- Objections without proper technical justification or references will be rejected by the expert committee without refund.
- Questions where multiple sources disagree — RRB prefers NCERT and Railway-specific official references over coaching material or private publications.
- Challenges to the exam schedule, question difficulty, or number of questions in each subject — these are administrative decisions, not objectionable errors.
- Fee per objection: ₹50 + applicable bank charges (UPI, net banking, debit/credit card accepted)
- If your objection is found correct and valid by the RRB expert committee: ₹50 is refunded (bank charges deducted) to your registered bank account after the final answer key is published
- If your objection is rejected as incorrect or invalid: ₹50 is forfeited — no appeal process
- There is no limit on the number of objections you can raise — but each costs ₹50
- Refunds are credited within 4–6 weeks after the final answer key publication
Answer key links are activated on all regional RRB websites simultaneously. Use your region's website for faster access, or use the centralized portal rrb.digialm.com which works for all zones.
RRB Technician CEN 02/2025 has a three-stage selection process. The CBT merit list is the only competitive stage — DV and ME are qualifying in nature. Here is the complete roadmap from exam to appointment.

After 27 March 2026 at 10:00 AM, the RRB enters a review phase. Here is a clear timeline of what to expect next — and what you should be doing in the meantime.
Objection Review — Expert Committee (March–April 2026)
After the window closes, an RRB expert committee reviews all valid objections received from candidates. They check each challenged question against authoritative references. If any objection is upheld, the answer key for that question is modified for all candidates — the benefit applies universally, not just to the objector.
Final Answer Key Publication (April–May 2026)
The revised final answer key is published on all RRB websites. At this stage, valid objection fees are refunded. No further challenges to the final key are entertained by the RRB — this is the definitive answer key used to prepare the merit list.
Score Normalisation & Merit List (May 2026)
Since CBT was conducted over 4 days in multiple shifts, raw scores are normalised to account for differences in question difficulty between shifts. The z-score based normalisation formula is applied. Normalised scores are used to prepare the community-wise, zone-wise merit list.
CBT Result Declaration (May–June 2026)
The CBT result is published on all regional RRB websites. Shortlisted candidates for Document Verification are announced by community and zone. The DV call letter contains reporting date, venue, and list of documents required. Only 1× vacancies per community per zone are called for DV.
Document Verification & Medical Examination (July–September 2026)
DV and ME are conducted at Railway Division headquarters. Candidates who clear both receive appointment letters and are posted to their allocated zones and divisions. Joining happens on the notified date — typically within 30–60 days of appointment letter.
