Railway Recruitment Boards (RRBs) Assistant Loco Pilot 2026 Answer Key

Overview of RRB Assistant Loco Pilot (ALP) CBT 1 2026 Answer Key

The Railway Recruitment Boards (RRBs) conduct the Assistant Loco Pilot (ALP) examination to recruit technical staff across Indian Railways zones. Following the successful completion of the Computer Based Test (CBT 1) held on November 3, 2026, the board publishes the provisional answer key alongside candidate response sheets. This document serves as an official reference for candidates to verify their marked options against the correct answers determined by subject matter experts.

Provisional vs Final Answer Key: Key Differences

Understanding the distinction between the provisional and final answer keys is essential for every candidate:

• Provisional Answer Key: Released shortly after the examination. It presents the tentative correct answers. Candidates are invited to review the key, raise objections, and challenge any discrepancies by paying a prescribed fee.
• Final Answer Key: Published after a panel of subject experts reviews all candidate challenges. If an objection is valid, corrections are incorporated. The final answer key is non-contestable, and the RRB evaluates CBT 1 raw scores exclusively based on this revised version.

How to Calculate Your Estimated Score Using the Answer Key

The RRB ALP CBT 1 test paper consists of 75 multiple-choice questions carrying one mark each, with a total duration of 60 minutes. The examination enforces negative marking for incorrect responses.

Marking Scheme

• Correct Answer: +1 mark
• Incorrect Answer: -1/3 (0.33) mark
• Unattempted Question: 0 marks

Score Calculation Formula

Use the following formula to compute your raw score:

Estimated Raw Score = (Total Correct Answers × 1) - (Total Incorrect Answers × 0.333)

Practical Example

Suppose you attempted 60 questions out of 75. Upon checking with the official answer key, you find:

• Number of Correct Answers: 48
• Number of Incorrect Answers: 12
• Number of Unattempted Questions: 15

Calculation: (48 × 1) - (12 × 0.333) = 48 - 4.00 = 44.00 Marks.

Section-Wise Comparison and Category-Wise Cut-Off Estimation

CBT 1 includes Mathematics, Mental Ability, General Science, and General Awareness. To gauge your qualification chances, break down your performance section by section:

RRB mandates minimum qualifying marks for CBT 1: 40% for UR and EWS, 30% for OBC (NCL), 30% for SC, and 25% for ST candidates. However, qualifying CBT 1 to enter CBT 2 requires clearing the competitive cut-off, which varies by RRB zone and vacancy distribution. Zone-wise cut-off marks are not specified here and are published by each RRB with its result.

Complete Process to Raise an Objection

If you identify an error in the question framing, translation, or the provided answer, you can challenge it via the official portal:

• Portal: The objection link is activated on the regional RRB websites alongside the answer key.
• Timeframe: The objection window is open for a limited period; the exact duration is not specified here and is announced along with the answer key.
• Objection Fee: Candidates must pay Rs. 50 plus applicable bank service charges per challenged question.
• Documentation: You must upload authentic documentary evidence or standard textbook references to substantiate your claim.
• Expert Evaluation: Subject matter experts review each challenge thoroughly before preparing the final answer key.

What Happens If Your Objection Is Accepted?

If the subject expert committee validates your objection:

• The answer key is officially amended for all candidates across that shift.
• The full objection fee of Rs. 50 is refunded to the original payment account.
• If a question is declared incorrect or ambiguous, it is either scrapped or full marks are awarded to all candidates, and score evaluation is prorated out of the remaining valid questions.
• A revised, final answer key is published on the portal prior to the CBT 1 result declaration.

What Happens If Your Objection Is Rejected?

If the committee determines that the initial answer key was correct:

• The challenge fee of Rs. 50 is forfeited.
• No individual correspondence or representation is entertained regarding the decision.
• The decision of the RRB expert panel remains final and binding. Filing an RTI request does not alter the evaluation, as RTIs can only provide factual records, not challenge academic evaluations by an expert board.

Realistic Evaluation of Your Qualifying Prospects

Do not overestimate your score by ignoring negative markings or assuming disputed answers will automatically swing in your favour. Similarly, avoid underestimating your prospects if your raw score is moderate, because CBT 1 raw scores undergo statistical normalisation to account for shift-wise difficulty variations. Focus on whether your score falls comfortably above the baseline minimum qualifying percentages and historical regional trends.

Tips to Avoid Common Score Calculation Mistakes

• Double-check Question IDs: Match the Question ID and Option ID carefully, especially since questions and options are shuffled across shifts.
• Account for Negative Marks: Deducting 0.25 instead of 0.33 is a frequent error. Always deduct one-third mark for every incorrect answer.
• Ignore Ambiguous Unofficial Keys: Rely solely on the official response sheet issued by the RRB, as unofficial keys from third parties often contain discrepancies.
• Save Submission Receipts: When submitting objections, ensure transaction slips and objection reference numbers are saved for future reference.
