RRB ALP Syllabus 2026: CBT 1, CBT 2, CBAT + PDF

The RRB ALP syllabus covers four assessment stages — CBT 1 (Mathematics, General Intelligence & Reasoning, and General Science), CBT 2 (Part A: Maths, Reasoning and Basic Science & Engineering + Part B: your trade-specific topics), the CBAT psycho aptitude test, and finally Document Verification with a Medical Examination. In the revised 2026 pattern, General Awareness has been de-emphasised in CBT 1, and the final merit is built on 50% CBT 2 Part A + 50% CBAT scores. This guide gives you the complete topic-wise syllabus for every stage, the exam pattern with marks and duration, the marking and negative-marking scheme, category-wise qualifying marks, high-yield priorities, and how to download the syllabus PDF.

Last reviewed: August 2026. Exam patterns can change between recruitment cycles — always cross-check every detail against the official RRB notification for your cycle (see the PDF section below).

RRB ALP Syllabus 2026: Quick Overview

The Railway Recruitment Board (RRB) conducts the Assistant Loco Pilot (ALP) recruitment through a strictly stage-wise selection process. You must clear each stage to advance to the next, and the syllabus deepens as you progress — from general aptitude in CBT 1 to trade-engineering topics in CBT 2 Part B and psychomotor testing in the CBAT. Understanding the rrb alp syllabus 2026 in full is the single biggest lever for building an efficient study plan, because a large chunk of CBT 1 and CBT 2 Part A overlaps, letting you prepare both stages together.

Here is a snapshot of the full journey before we break down each stage in detail.

What Changed This Year: RRB ALP 2026 Pattern Update

Before you touch a single topic, read this box carefully — many older guides and PDFs online still teach the outdated pattern, and studying the wrong syllabus wastes weeks.

• General Awareness de-emphasised in CBT 1: The revised CBT 1 structure focuses on Mathematics, General Intelligence & Reasoning, and General Science. The prominent standalone General Awareness & Current Affairs scoring block that older ALP notices carried no longer dominates the streamlined structure — so do not over-invest in static GK for CBT 1. Confirm the exact composition in your cycle’s notification.
• Merit weightage shifted to 50:50: In earlier cycles CBAT and CBT 2 Part A were combined in a different ratio. In the current framework, the final merit is calculated as 50% CBT 2 Part A + 50% CBAT. This makes the psycho test decisive — you can no longer treat it as a formality.
• Part B stays qualifying: CBT 2 Part B (trade paper) remains qualifying only, needing 35% to pass, and does not add to your merit score.

The takeaway: if you are aiming for a strong rank, CBAT preparation is now as important as your aptitude score — treat both as merit subjects.

RRB ALP Selection Process: How Many Stages?

There are effectively four assessment stages followed by verification. The full RRB ALP selection process runs in this order:

• Stage 1 — CBT 1 (Computer Based Test 1): A screening test. Your score here only decides whether you qualify for CBT 2; it is not added to the final merit.
• Stage 2 — CBT 2 (Part A + Part B): The main written stage. Part A is merit-deciding; Part B is a qualifying trade test.
• Stage 3 — CBAT (Computer Based Aptitude Test): A psycho aptitude test taken only by candidates who qualify Part A and opt for ALP. It is merit-deciding.
• Stage 4 — Document Verification & Medical Examination: Final shortlisting based on merit, followed by a stringent A-1 vision medical standard specific to loco pilots.

Because only CBT 2 Part A and CBAT feed the merit list, your entire strategy should be to qualify CBT 1 and Part B comfortably while maximising Part A and CBAT.

RRB ALP Exam Pattern 2026: Marks & Duration

The full rrb alp exam pattern 2026 across all computer-based stages is summarised below. Note the time relaxations and separate structures for CBT 2’s two parts.

CBT 2 Part A and Part B are taken back-to-back in a single sitting (90 + 60 minutes). Candidates from PwBD categories receive additional compensatory time (typically a scribe and extra minutes) as per RRB norms. Both CBT 1 and CBT 2 carry a fixed 1 mark per correct answer.

In How Many Languages Is the RRB ALP Exam Held?

RRB computer-based tests are typically offered in English, Hindi and around thirteen regional languages (such as Tamil, Telugu, Marathi, Bengali, Gujarati, Kannada, Malayalam, Odia, Punjabi, Assamese, Urdu, Konkani and Manipuri). You choose your question-paper medium during the application; the exact list is confirmed in the official notification. This matters for preparation — practise reading technical CBT 2 terms in your chosen medium so wording does not slow you down on exam day.

Is There Negative Marking in the RRB ALP Exam?

Yes. Both CBT 1 and CBT 2 have negative marking of one-third (1/3) mark deducted for every wrong answer. So for every three incorrect attempts, you lose one full mark. The CBAT has no negative marking, but it uses a battery-based scoring system where accuracy and speed both matter. Practise smart attempting — blind guessing in the CBTs actively pulls your score down.

Category-Wise Qualifying Marks (CBT 1 & CBT 2)

To be shortlisted from the CBTs you must clear the minimum qualifying percentage set for your category. RRB norms generally follow the pattern below; verify the exact figures in your notification, as relaxations can be revised.

Note that these are only the qualifying floors — actual cut-offs to advance are decided by vacancies and competition and usually run well above them, especially for CBT 1.

RRB ALP CBT 1 Syllabus: Topic-Wise Breakdown

The rrb alp cbt 1 syllabus tests three subjects at roughly matric / 10th standard difficulty. CBT 1 is purely qualifying, but the cut-offs are high, so you must be fast and accurate. Here is the section-wise topic list.

Printable CBT 1 Revision Checklist

Tick each block as you master it:

• ☐ Maths: BODMAS & simplification
• ☐ Maths: Percentage, ratio, average, profit-loss
• ☐ Maths: Time-speed-distance & time-work
• ☐ Maths: Mensuration (2D & 3D areas/volumes)
• ☐ Maths: Trigonometry & basic geometry
• ☐ Reasoning: Coding-decoding & series
• ☐ Reasoning: Syllogism & Venn diagrams
• ☐ Reasoning: Blood relations & directions
• ☐ Reasoning: Analogy & classification
• ☐ Science: Physics — motion, electricity, light
• ☐ Science: Chemistry — acids, metals, reactions
• ☐ Science: Biology — human body, cell, diseases

Is General Awareness Removed from RRB ALP CBT 1?

In the revised streamlined CBT 1 structure, the emphasis is firmly on Mathematics, General Intelligence & Reasoning, and General Science, and the prominent standalone General Awareness & Current Affairs scoring head no longer dominates as it did in earlier notices. Always cross-check the exact number of GA questions in the official notification for your cycle, but plan your CBT 1 preparation around the three core subjects rather than heavy static GK. Aspirants who still want light current-affairs coverage for interviews and general reading can use a monthly digest like the Vision IAS Current Affairs Magazine (January 2026) without over-investing time.

RRB ALP CBT 2 Syllabus: Part A & Part B Explained

CBT 2 is where the exam gets serious. The rrb alp cbt 2 syllabus splits into two papers written in a single sitting: Part A (100 questions, 90 minutes) is merit-deciding, and Part B (75 questions, 60 minutes) is a qualifying trade test.

What Is the Difference Between CBT 2 Part A and Part B?

Part A is a general aptitude and basic-engineering paper common to all candidates, and its normalised score is 50% of your final merit. Part B is trade-specific — the topics depend on the ITI trade or engineering diploma you applied under — and you only need 35% to qualify; it does not add to merit. In short: Part A decides your rank, Part B decides your eligibility.

CBT 2 Part A Syllabus (Merit-Deciding)

CBT 2 Part B Syllabus (Trade-Wise, Qualifying)

Part B is based on the syllabus prescribed by the Directorate General of Training (DGT/DGET) for your relevant trade. Below is a trade-wise topic map — most competing guides only name the trades, so use this as your quick reference.

Trade Eligibility Mapping

Choosing the correct Part B module matters because it must match your qualifying ITI/Diploma. Use this mapping to pick your trade paper:

CBT 1 vs CBT 2 Syllabus Overlap: Study Efficiently

Here is a gap most guides ignore: a large part of CBT 1 repeats in CBT 2 Part A. Mathematics and Reasoning are common to both stages — only the difficulty rises in CBT 2 — and General Science in CBT 1 flows naturally into Basic Science & Engineering in Part A. This means one strong foundation in Maths and Reasoning can carry you through both merit-relevant stages.

Strategy: master Maths and Reasoning first (they cover both stages and 50% of merit-relevant Part A), then layer Basic Science & Engineering and your trade topics.

RRB ALP CBAT Syllabus: The Psycho Aptitude Test

The rrb alp cbat syllabus is unlike any written test — it measures psychomotor and cognitive traits critical for safely driving a train. Only candidates who qualify CBT 2 Part A and opt for the ALP post are called for the CBAT. Since it now carries 50% of final merit, it deserves dedicated practice.

What Is the CBAT and Is It Qualifying?

The CBAT (Computer Based Aptitude Test), also called the psycho test or Aptitude Test, is both qualifying and merit-deciding. You must secure the minimum qualifying marks in each of the test batteries — there is no relaxation for any category in the CBAT qualifying standard — and your overall performance then contributes 50% to the merit list.

The 5 CBAT Test Batteries

How to Practise the Psycho Test

• Train speed with accuracy: The CBAT rewards fast and correct responses. Use timed drills so you build instinctive pace without panicking.
• Practise on-screen: The test is fully computer-based — rehearse on a screen, not on paper, so the interface feels natural on exam day.
• Qualify every battery: A brilliant Memory score cannot rescue a failed Depth Perception battery — you must clear each one, so practise your weakest battery hardest.
• Stay calm & consistent: These batteries are designed to detect steadiness. Erratic performance hurts; steady, moderate-speed accuracy scores best.

Marking Scheme & Final Merit Calculation

Understanding exactly how marks convert to rank prevents strategic mistakes.

What Is the Weightage of CBAT in the Final Merit List?

In the current pattern, the final merit is computed as 50% weightage to CBT 2 Part A + 50% weightage to CBAT. Scores are normalised across shifts before combining. Because half your rank now depends on the psycho test, candidates who once ignored it can no longer afford to — a strong Part A with a mediocre CBAT will not produce a top rank.

RRB ALP Preparation Strategy & High-Yield Topics

Pure syllabus dumps do not get you selected — prioritisation does. Here is a marks-first plan:

• First 4 weeks: Lock down Mathematics and Reasoning fundamentals. They appear in CBT 1 and CBT 2 Part A and account for the bulk of merit-relevant scoring. Focus on BODMAS, percentage, ratio, time-work-distance, mensuration, coding-decoding, syllogism and series.
• Weeks 5–8: Add General Science (CBT 1) and Basic Science & Engineering (Part A) — engineering drawing, units, electricity and simple machines are high-frequency.
• Weeks 9–12: Drill your trade Part B to comfortably cross 35%, then start CBAT battery practice — it is worth 50% of merit and needs weeks of psychomotor conditioning, not last-minute cramming.
• Throughout: Solve previous-year papers and full-length mock tests under timed, negative-marking conditions.

For disciplined test practice, aspirants often adapt structured mock-test habits from established series such as the Vision IAS Prelims Test Series — the timed, negative-marking rhythm is exactly what CBT 1 and CBT 2 demand. And to build the habit of solving from past questions, a topic-wise PYQ resource like the Forum IAS Topic-Wise PYQ Toolkit models the disciplined, exam-pattern-first approach that works equally well for railway aspirants building their own ALP question bank.

Recommended Books for RRB ALP 2026

Pair one book per subject with a heavy diet of mock tests — for railway CBTs, practice volume beats theory volume.

Common Mistakes to Avoid

• Studying the old pattern: Preparing heavy General Awareness for CBT 1 or treating CBAT as a formality — both are outdated approaches under the 2026 structure.
• Ignoring negative marking: Over-attempting in the CBTs and losing 1/3 mark per wrong answer silently drags cut-off performance down.
• Neglecting the weakest CBAT battery: You must qualify every battery — one failed battery ends your candidature regardless of other scores.
• Skipping Part B practice: Assuming a qualifying paper is easy; a below-35% Part B disqualifies an otherwise strong candidate.
• No timed mocks: Knowing topics but never rehearsing speed under exam conditions.

Frequently Asked Questions

What is the syllabus of RRB ALP 2026?

The RRB ALP 2026 syllabus spans four stages: CBT 1 (Mathematics, General Intelligence & Reasoning, General Science), CBT 2 Part A (Maths, Reasoning, Basic Science & Engineering) and Part B (trade-specific topics for Electrical, Mechanical, Automobile or Electronics), and the CBAT psycho aptitude test with five batteries, followed by Document Verification and Medical.

Is there negative marking in the RRB ALP exam?

Yes. Both CBT 1 and CBT 2 deduct one-third (1/3) mark for every wrong answer, while each correct answer earns 1 mark. The CBAT has no negative marking but requires you to qualify each of its five test batteries separately.

How many stages are there in the RRB ALP selection process?

There are four assessment stages — CBT 1, CBT 2 (Part A and Part B), and CBAT — followed by Document Verification and a Medical Examination. Only CBT 2 Part A and CBAT contribute to the final merit list.

Is General Awareness removed from RRB ALP CBT 1?

In the revised streamlined CBT 1 pattern, the focus is on Mathematics, Reasoning and General Science, and the standalone General Awareness scoring head no longer dominates as it did in older notices. Always confirm the exact composition in the official notification for your cycle before planning static-GK study time.

What is the difference between CBT 2 Part A and Part B in RRB ALP?

Part A (100 questions, 90 minutes) is a common aptitude and basic-engineering paper whose normalised score forms 50% of your merit. Part B (75 questions, 60 minutes) is a trade-specific qualifying paper needing only 35% to pass and does not add to merit. Simply put, Part A decides your rank and Part B decides your eligibility.

What is the CBAT in RRB ALP and is it qualifying?

The CBAT (Computer Based Aptitude Test), or psycho test, measures memory, following directions, depth perception, concentration and perceptual speed. It is both qualifying — you must clear every battery — and merit-deciding, contributing 50% to the final merit list.

What is the weightage of CBAT in the final RRB ALP merit list?

The CBAT carries 50% weightage in the final merit, with CBT 2 Part A providing the other 50%. Scores are normalised across shifts before being combined, so a strong Part A alone cannot secure a top rank without an equally strong CBAT.

What is the qualifying mark for RRB ALP CBT 1 and CBT 2?

The minimum qualifying percentages generally are 40% for UR/EWS, 30% for OBC-NCL and SC, and 25% for ST. These are only floors — the effective cut-off to advance is set by vacancies and competition and is usually higher, especially for CBT 1. Confirm the current figures in your notification.

In how many languages is the RRB ALP exam conducted?

The RRB ALP CBTs are typically available in English, Hindi and around thirteen regional languages. You select your paper medium during the application, and the exact language list is confirmed in the official notification for the cycle.

How can I download the RRB ALP syllabus PDF?

Download the official RRB ALP syllabus PDF from the regional RRB website (such as rrbcdg.gov.in) as an annexure to the official notification, then pair it with the topic-wise checklists in this guide for a printable revision tracker covering CBT 1, CBT 2 and CBAT.
