Updated 16 October 2026: The RRB Technician Answer Key for the Technician Grade-I Signal CBT under CEN 02/2026 is available to view. Candidates can review their questions, recorded responses and answer keys, then submit objections through the official RRB window by 22 October 2026 at 23:55 hrs. This update concerns Grade-I Signal only; it does not announce an answer key for Technician Grade-III.
Use the official RRB login route to check your response sheet and follow the instructions shown there. Raise an objection only when you can identify a specific issue and support your claim. The objection window includes online fee payment, so do not leave submission until the final minutes. This guide covers the available dates, how to review the displayed information, the objection process and fee rules, and relevant details about the wider CEN 02/2026 recruitment.
RRB Technician Answer Key 2026: dates and objection window
| Activity | Date and time |
|---|---|
| Technician Grade-I Signal CBT | 9 October 2026 |
| Viewing of questions, responses and answer keys; objections and fee payment begin | 15 October 2026, from 16:00 hrs |
| Last time to view, object and pay | 22 October 2026, 23:55 hrs |
The viewing and objection facility opened after the Grade-I Signal computer-based test held on 9 October. The window is available for a limited period: the specified closing time is 22 October 2026 at 23:55 hrs. Candidates need to complete the objection submission and its online payment before that deadline. The RRBs have stated that representations received after the closing time will not be considered.
The notice relates to the Grade-I Signal CBT and should not be read as an announcement for every post in the recruitment. In particular, it does not confirm the release of a Grade-III answer key. Candidates for Grade-III should check their relevant official RRB pages for a separate notice rather than assume that the same key or window applies.
What is the RRB Technician Answer Key and what can candidates review?
The answer-key facility allows eligible Grade-I Signal candidates to see the questions, their recorded responses and the corresponding answer keys through the official login. These items allow a candidate to compare the response recorded for a question with the answer displayed by the RRB. Review the information in your own candidate account, since a circulated answer list may not show the same question or response details as your individual session. Use the RRB Technician Answer Key and your response sheet together to check the displayed information for each question.
Take time to check each question and its options in context. A disagreement should be tied to a specific question or answer key, not merely to a general impression of the paper. The online facility provides the prescribed route to submit an objection and gives instructions on the details required. Follow those instructions as displayed; the available notice does not provide a separate offline objection route.
Viewing the key and submitting a representation are separate actions. A candidate who only reviews the response sheet has not necessarily filed an objection. Similarly, entering objection details without completing the required fee payment may leave the process incomplete. Check the portal’s confirmation and payment status before leaving the facility.
How to check the answer key and submit an objection
The detailed instructions and objection procedure for the RRB Technician Answer Key are provided through the official RRB website link. Use the candidate login and on-screen directions for the Grade-I Signal CBT. The exact presentation of the link may be within the official portal, so start from an official RRB website or the RRB application portal rather than relying on a forwarded address.
- Open an official RRB website or the RRB application portal and locate the CEN 02/2026 Grade-I Signal answer-key link.
- Sign in using the credentials requested on the official page. Do not share your login credentials with another person.
- Open the response sheet and review the question paper, your recorded responses and the corresponding answer key carefully.
- If you identify an issue, select the question, option or answer key that you believe is incorrect and enter the objection details required by the portal.
- Review the question reference and objection information before proceeding. Check the fee shown for the objection and make the online payment using an available method.
- Confirm that the submission and payment have completed successfully. Retain the confirmation or payment record for your own reference.
Before submitting, make sure the question number and the displayed question correspond to the issue you intend to raise. Read the objection instructions on the portal, including any information it requests to support the claim. The RRBs’ decision on objections is final and binding, and no further correspondence on that decision will be entertained. Avoid submitting duplicate or unrelated claims simply because the objection facility is open.
How to raise a considered objection
A useful first step is to review the response sheet from beginning to end, then return to any question where you see a possible discrepancy. Compare the question wording and options shown in your login with the answer key for that question. Confirm that you are considering the recorded response and not confusing it with the answer that you believe is correct. This careful comparison helps you identify what you are challenging.
Next, check the objection form itself. Use the question or option selection provided by the portal and describe the specific issue in the manner the form requests. The published details here do not specify a required evidence format or promise that every objection will receive an individual explanation. Follow the live portal instructions rather than assuming that a particular attachment, wording or submission method is accepted.
Finally, verify the selected question and the amount payable before authorising payment. The fee is charged for each question, so more than one objection may mean more than one question-level charge. Do not wait until the last few minutes to begin: you need to complete both the online representation and the applicable payment before the window closes. Keep your own transaction record in case you need to refer to it later.
RRB Technician objection fee and refund rules
| Item | Rule |
|---|---|
| Fee | ₹50 for each question, plus applicable bank service charges |
| If an objection is accepted as correct | The fee for that objection is refunded, after deduction of bank charges, to the account used for payment |
| Payment methods listed | Debit card, credit card, UPI and net banking |
The fee is charged per question, not as one flat payment for the entire objection submission. If you challenge more than one question, review the portal’s fee information for each one and confirm the total payable amount before completing the transactions. Applicable bank service charges are additional to the stated ₹50 question-level fee.
If an objection is accepted as correct, the fee for that objection is refunded to the account used for payment after bank charges are deducted. The stated refund condition is linked to the objection being found correct; it should not be treated as a guarantee that every submitted objection will be refunded. The listed payment methods are debit card, credit card, UPI and net banking, but the options displayed in the official login should be checked before payment.
Important checks before the objection deadline
- Confirm that you are viewing the Grade-I Signal response sheet. The released notice does not cover a Grade-III answer key.
- Compare the answer key with the question and options displayed in your own login rather than relying only on a circulated answer list.
- Check that the question you select in the objection facility is the question you mean to challenge.
- Submit each objection through the official facility and verify that both submission and payment have completed successfully.
- Keep a record of objection details and payment confirmation for your reference.
- Do not share your login credentials, payment details or account access with another person.
- Use official Railway Recruitment Board pages for the latest notice or any change to the window.
- Complete the process before 22 October 2026 at 23:55 hrs; late representations will not be considered.

Eligibility, age and pay: recruitment details
The following summary reflects the qualification and age information stated for the two post groups. Grade-III requirements are not identical for every trade, so candidates must consult the relevant trade entry in the official notification for the precise qualification. This summary is background information for CEN 02/2026; it is not a substitute for the detailed recruitment rules.
| Post | Qualification stated in the notification | Age limit | Initial basic pay |
|---|---|---|---|
| Technician Grade-I Signal | B.Sc. in Physics, Electronics, Computer Science, IT or Instrumentation; or a three-year diploma or degree in engineering in the specified streams | 18–33 years | ₹29,200 per month (Level 5) |
| Technician Grade-III | Class 10/SSLC plus the specified National or State Trade Certificate (ITI), or Course Completed Act Apprenticeship in the relevant trade. The stated Grade-III S&T route also includes 10+2 with Physics and Mathematics. | 18–30 years | ₹19,900 per month (Level 2) |
Age was reckoned as on 1 July 2026. The stated relaxations include 3 years for OBC-NCL, 5 years for SC/ST and 10 years for PwBD candidates in UR/EWS categories. Further relaxations for Ex-Servicemen and other eligible categories are governed by the recruitment rules. Applicants should use the notification to check the category conditions applicable to them rather than assume that a single relaxation applies to every case.
The figures shown are initial basic pay, not take-home salary. Applicable allowances and deductions affect the amount paid. Selection is through a Computer Based Test, followed by Document Verification and the prescribed medical examination. Meeting the stated eligibility requirements or minimum CBT qualifying marks does not by itself establish final selection.
CBT pattern and recruitment stages
The Grade-I Signal and Grade-III CBTs use different subject weightings. Both patterns listed below total 100 questions and 100 marks, with a test duration of 90 minutes. The marking rule includes a deduction of one-third mark for each wrong answer. Candidates reviewing their own test records should rely on the details displayed for their exam and the official notification.
| Grade | Subjects and marks | Duration and marking |
|---|---|---|
| Technician Grade-I Signal | General Awareness 10; General Intelligence and Reasoning 15; Basics of Computers and Applications 20; Mathematics 20; Basic Science and Engineering 35. Total: 100 questions, 100 marks. | 90 minutes; one-third mark deducted for each wrong answer |
| Technician Grade-III | Mathematics 25; General Intelligence and Reasoning 25; General Science 40; General Awareness 10. Total: 100 questions, 100 marks. | 90 minutes; one-third mark deducted for each wrong answer |
The stated minimum qualifying marks are 40% for UR/EWS, 30% for OBC-NCL and SC, and 25% for ST candidates. These are minimum qualifying thresholds. Meeting one does not by itself guarantee shortlisting, because selection also depends on the applicable merit and recruitment rules. The listed next stages are Document Verification and the prescribed medical examination.
Exam-day documents and instructions
Although the CBT has concluded, the following information helps candidates understand the records and instructions associated with the exam. The e-call letter was downloaded through the official RRB login; it was not sent by post. Candidates were instructed to check the relevant e-call letter and official notice for the directions applicable to them.
| Item | What candidates were instructed to carry or check |
|---|---|
| E-call letter | Printout of the candidate’s own e-call letter from the official RRB login |
| Photo identity document | Original accepted photo ID, such as Voter ID, Aadhaar/e-Aadhaar printout, driving licence, PAN, passport, eligible employer ID or school/college ID, as applicable |
| Aadhaar for biometrics | Original Aadhaar or printout of e-verified Aadhaar; Aadhaar was to be kept unlocked in UIDAI for verification |
| Photograph | Colour passport photograph not more than two months old on the CBT date |
| SC/ST travel authority | For eligible candidates using the travel facility, original community certificate and original photo ID were required for the journey |
| Scribe, if opted | The scribe needed the separate e-call letter and the original ID used at registration |
Exam-centre instructions prohibited items including phones, watches, earphones, calculators, books, paper, writing instruments, bags and cameras. Candidates were told not to apply henna on their hands or feet because it can interfere with biometric capture. The self-declaration, signature and left-thumb impression were to be completed only in the exam hall as directed by the invigilator—not in advance. Always follow the instructions printed on the relevant e-call letter and official notice.

Next steps and common mistakes to avoid
- Do not wait until the deadline: complete both objection submission and payment before 22 October at 23:55 hrs.
- Do not confuse the grades: the current answer-key notice is for Grade-I Signal only; verify any Grade-III update separately on an official RRB site.
- Do not object without checking the displayed paper: confirm the question number, options and recorded response in your own login.
- Do not assume a saved form is complete: check that the portal confirms the submission and the required payment.
- Do not rely on forwarded links or agents: open official Railway Recruitment Board pages directly and avoid sharing credentials or paying unofficial intermediaries.
- Keep your records: retain available objection and payment confirmation details for your reference.
- Check official updates: watch the RRB portal for subsequent recruitment notices; do not assume an unannounced result date or Grade-III key release.
Final takeaway
The Grade-I Signal answer key and response details for CEN 02/2026 are available for review through the official RRB login. If you find a genuine, specific error, submit a question-level objection and pay ₹50 per question, plus applicable bank charges, by 22 October 2026 at 23:55 hrs. The notice does not establish that the Grade-III key has been released. The RRBs’ decision on objections is final and binding. For any change to the window or later recruitment information, rely on official RRB channels. Check the RRB Technician Answer Key details in your login and confirm that any objection and payment are complete before the deadline.
