RRB ALP Syllabus 2026: CBT 1, CBT 2, CBAT & PDF Download

The rrb alp syllabus for 2026 covers four selection stages — CBT 1 (Mathematics, General Intelligence & Reasoning, General Science), CBT 2 (Part A on aptitude and basic engineering plus a trade-specific Part B), the Computer-Based Aptitude Test or CBAT, and finally Document Verification with a medical examination. The final merit list is built only from CBT 2 Part A and the CBAT, combined in a 70:30 weightage (Part A : CBAT), as per the latest RRB Centralised Employment Notice. This guide breaks down every subject, topic, marks pattern, and trade group so you know exactly what to study for the Assistant Loco Pilot exam.

If you are an aspirant searching for the full, up-to-date syllabus, an honest weightage figure (there is a lot of conflicting 50:50 vs 70:30 information floating around), topic-level priorities, and a clean PDF to prepare from, this page is built to be the single most complete resource you need. We cover the revised 2026 pattern, Hindi-medium topic names, previous-year trends, a working-aspirant study plan, and how to actually train for the CBAT.

RRB ALP Syllabus 2026: Overview and Selection Process

Assistant Loco Pilot (ALP) is one of the most sought-after technical posts in the Indian Railways, recruited by the Railway Recruitment Boards (RRBs) under a Centralised Employment Notice (CEN). The selection is purely merit-driven across multiple computer-based stages, with no interview. Understanding the full journey — and where marks actually count — is the first step to a smart preparation plan.

The RRB ALP selection process for 2026 has four distinct stages:

• Stage 1 — CBT 1 (First Stage Computer-Based Test): A screening test. Qualifying in nature; marks are used only to shortlist candidates for CBT 2 (typically 15 times the number of vacancies, community-wise).
• Stage 2 — CBT 2 (Second Stage Computer-Based Test): Has two parts in a single sitting — Part A (counts toward merit) and Part B (qualifying only, trade-specific).
• Stage 3 — CBAT (Computer-Based Aptitude Test): Also called the psycho test or aptitude test. Qualifying-cum-merit — you must clear it, and it contributes 30% to the final merit.
• Stage 4 — Document Verification (DV) & Medical Examination: Final stage. ALP requires a stringent A-1 medical fitness standard (vision, colour perception, hearing).

Here is the stage flow at a glance:

New Changes in RRB ALP Syllabus and Exam Pattern 2026

The most important update aspirants must register is the revision to CBT 1. In the latest pattern, General Awareness and Current Affairs has been reduced in emphasis from the older structure, and the CBT 1 now centres squarely on Mathematics, General Intelligence & Reasoning, and General Science (with general-awareness elements folded lightly into the paper). This means your CBT 1 preparation should be heavily weighted toward quantitative and reasoning ability rather than rote GK.

Key 2026 changes to note:

• CBT 1 emphasis shifted to Maths + Reasoning + General Science; less standalone current-affairs load than older cycles.
• Negative marking confirmed at 1/3 mark per wrong answer across CBTs.
• CBAT continues to be mandatory and qualifying for ALP (it is required for Loco Pilot duties, unlike some technician posts).
• Final merit officially weighted 70% CBT 2 Part A : 30% CBAT — the correct, current figure (see the dedicated section below to settle the 50:50 confusion).

RRB ALP Exam Pattern 2026 (CBT 1)

CBT 1 is a 60-minute online test of 75 questions carrying 75 marks (one mark each). The duration is extended to 80 minutes for PwBD candidates eligible for a scribe. Negative marking is 1/3 mark per wrong answer, so blind guessing hurts. The exam is offered in English, Hindi, and several regional languages.

Key facts: Total duration 60 minutes; 1 mark per correct answer; 1/3 negative marking; normalisation applied across shifts. CBT 1 is only a qualifying screen — once you clear the cut-off and make the 1:15 shortlist, your CBT 1 score is discarded for merit. Treat it as a hurdle to jump quickly and accurately.

What is the minimum qualifying percentage (cut-off) for CBT 1?

CBT 1 has a category-wise minimum qualifying percentage you must cross before your normalised score is even considered for the 1:15 shortlist. The standard RRB thresholds are:

Clearing this minimum only makes you eligible; the actual shortlisting cut-off is usually far higher and depends on vacancies, shift difficulty, and normalisation. Aim well above the floor, not at it.

What subjects are in RRB ALP CBT 1?

CBT 1 tests three core subjects — Mathematics, General Intelligence & Reasoning, and General Science — with a light current-affairs component. Reasoning carries the most questions (25), so it is the highest-yield section for a screening test.

RRB ALP CBT 1 Syllabus 2026 (Revised): Subject-Wise Topics

Below is the complete, topic-level CBT 1 syllabus with an indicative number of questions you can expect per topic, based on previous-year RRB ALP/Technician trends. Use the weightage to prioritise — do not spread your time evenly across topics that historically yield only one question.

Mathematics (20 marks)

General Intelligence & Reasoning (25 marks)

General Science (20 marks)

General Science is built on the NCERT Class 9 and 10 syllabus of Physics, Chemistry, and Life Sciences. This is the easiest section to score in if you have a strong school-level foundation.

RRB ALP CBT 2 Exam Pattern 2026 (Part A and Part B)

CBT 2 is the decisive stage — and the only CBT whose marks (Part A) carry into the final merit. It is conducted in a single sitting of 2 hours 30 minutes (150 minutes), split into two parts. Part A and Part B are taken back-to-back; there is no separate break, but the timer is allotted per part.

Part B qualifying mark: You only need 35% in Part B to qualify — it does not add to your merit score, but failing it eliminates you. Part A is where the real competition happens, so most of your merit-focused effort should go there. Negative marking of 1/3 applies in both parts.

What is the difference between CBT 1 and CBT 2 in RRB ALP?

CBT 1 is a 75-question, 60-minute qualifying screen on Maths, Reasoning and General Science whose marks do not count toward merit. CBT 2 is a longer 175-question, 150-minute test with a merit-counting Part A (100 Q) and a qualifying trade-based Part B (75 Q). Here is a quick comparison:

RRB ALP CBT 2 Syllabus 2026: Part A (Merit-Counting)

Part A has 100 questions across three areas. The Maths and Reasoning topics extend the CBT 1 list at a slightly higher difficulty, while Basic Science & Engineering is the new addition you must master.

Mathematics (Part A)

All CBT 1 Maths topics apply, with more weight on Mensuration, Trigonometry, Geometry, Algebra, Time-Speed-Distance, and Data Interpretation. Expect tougher, multi-step word problems.

General Intelligence & Reasoning (Part A)

Same topic bank as CBT 1 — analogies, syllogism, coding-decoding, Venn diagrams, series, directions, data sufficiency, analytical reasoning — at a higher complexity, with more puzzle-based questions.

Basic Science & Engineering (Part A)

This is the high-yield differentiator in Part A. It tests applied technical fundamentals common to all trades:

RRB ALP CBT 2 Syllabus 2026: Part B (Trade-Wise / Technical)

Part B is the 75-question qualifying trade paper. The syllabus is based on the trade (the relevant ITI / diploma / degree subject) through which you became eligible. It draws from the curriculum prescribed by the Directorate General of Training (DGT) for the trades designated by the NCVT/SCVT (for ITI holders), or the relevant diploma/degree engineering stream.

The major trade groups and their core technical topics are:

Which trade should I choose for RRB ALP CBT 2 Part B?

You do not freely "choose" a trade — you select the Part B trade that matches the qualification you applied with. Use this simple "find your trade" lookup based on your educational qualification:

Tip: If your qualification maps to more than one trade option, pick the one whose syllabus you know best — Part B is only qualifying (35%), so you want the path of least resistance, not the "prestige" trade.

RRB ALP CBAT (Psycho Test): Syllabus, Traits and Scoring

The Computer-Based Aptitude Test (CBAT), commonly called the psycho test, is unique to the Assistant Loco Pilot post and is mandatory and qualifying-cum-merit. It assesses whether you have the psychological aptitude to safely operate a locomotive — concentration, speed-with-accuracy, vigilance, and stable reaction under monotony.

What is CBAT in RRB ALP and is it qualifying?

Yes — CBAT is both qualifying and merit-counting. You must secure a minimum of 42 marks in each of the test batteries to qualify (no relaxation for any community, since it is a safety-critical assessment), and your CBAT performance then contributes 30% to the final merit. Reading glasses/lenses are not permitted during the test.

The CBAT is administered in English and Hindi only. It is a battery of psychometric sub-tests, typically including:

Scoring mechanics: Each battery is scored separately; you must clear the minimum in every battery — a single low battery score fails you, regardless of how strong the others are. There is no negative marking in CBAT, but speed-accuracy trade-off is the core skill being measured: rushing produces errors, and over-caution produces too few attempts. The only reliable way to improve is repeated, timed mock CBAT practice so the test format feels automatic on exam day.

How Is the RRB ALP Final Merit List Calculated? (70:30 Settled)

This is the single most-confused point across competitor pages — some quote 50:50, others 70:30. Here is the clear, source-cited position as per the RRB ALP CEN and official scheme of exam:

Final merit = 70% of CBT 2 Part A normalised marks + 30% of CBAT marks.

So neither CBT 1 nor Part B adds a single mark to your final rank. Only Part A and CBAT do, in a 70:30 ratio. The practical takeaway: CBT 2 Part A is where you win or lose your selection, with CBAT as a crucial qualifying multiplier you cannot afford to fumble. Always cross-check the exact ratio in the year’s official CEN, as the RRB reserves the right to revise it.

RRB ALP Subject Weightage: CBT 1 and CBT 2 at a Glance

Pulling all the marks together helps you allocate study hours rationally:

Is There Negative Marking in the RRB ALP Exam?

Yes. Both CBT 1 and CBT 2 carry a negative marking of 1/3 mark for every wrong answer. Three wrong guesses cancel out one correct answer, so unattempted questions are safer than reckless guessing. The CBAT, by contrast, has no negative marking — but it rewards speed with accuracy, so the discipline is different. Build a habit in CBT mocks of attempting only what you can reasonably solve, and use educated elimination (not blind guessing) on borderline questions.

How to Prepare for RRB ALP 2026: Stage-Wise Strategy

A realistic plan matters more than a perfect one — especially for working aspirants and ITI students balancing practicals. Here is a stage-wise approach that mirrors how the exam actually unfolds.

Phase 1 (Months 1-2): Build the CBT 1 base

• Revise NCERT Class 9-10 Science thoroughly — it powers both CBT 1 Science and CBT 2 Basic Science.
• Master Maths shortcuts for percentages, ratio, profit-loss, time-work, and speed-distance.
• Do 30 minutes of reasoning daily — it is the highest-scoring CBT 1 section.

Phase 2 (Months 3-4): Add CBT 2 Part A depth

• Start Basic Science & Engineering — engineering drawing, basic electricity, units, levers, heat.
• Raise Maths and Reasoning to CBT 2 difficulty with multi-step problems.
• Begin one full-length CBT 1 mock per week; analyse every error.

Phase 3 (Months 5-6): Trade (Part B) + CBAT

• Cover your Part B trade syllabus to a comfortable 50%+ level (only 35% is needed).
• Start CBAT mock batteries 2-3 times a week — this is a trainable skill, not a fixed trait.
• Shift to alternate-day full mocks of CBT 1 and CBT 2.

Sample weekly timetable for working aspirants

For NCERT-level science fundamentals that underpin both CBT 1 General Science and CBT 2 Basic Science & Engineering, structured printed modules help a lot. Aspirants targeting concept clarity in physics often find module-based sets like the eSaral IIT JEE Modules 2026 useful for building a rock-solid Class 11-12 physics and chemistry base that transfers directly to the engineering-science portions.

Previous-Year Trend Analysis: Which Topics Repeat?

Looking across recent RRB ALP and Technician CBTs, a few patterns repeat reliably and deserve priority:

• Reasoning: Analogies, syllogism, and mathematical operations together account for the largest, most predictable chunk — typically 8-10 of the 25 reasoning questions.
• Maths: Percentage, ratio-proportion, profit-loss, and time-speed-distance dominate; mensuration and trigonometry appear consistently in CBT 2.
• Science: Physics (electricity, motion, work-energy) repeatedly outweighs chemistry and biology in question count.
• Basic Science & Engineering (CBT 2): Basic electricity, units & measurements, and engineering drawing are perennial high-yield areas.

The lesson: a candidate who fully secures reasoning + physics + the four staple maths topics has already locked a large, predictable share of marks before touching the harder long-tail topics.

RRB ALP Syllabus in Hindi (हिंदी में)

RRB ALP has a huge Hindi-medium audience, and the CBT is fully available in Hindi. Here are the key subject and topic names in Hindi so Hindi-medium aspirants can map their study material correctly:

Hindi-medium aspirants should ensure they practise reasoning and science questions in Hindi too, since translated phrasing can differ subtly from English. Printed Hindi study material that builds general science and reasoning fundamentals — such as the Drishti IAS Hindi Study Material — can reinforce the conceptual base in your medium of comfort, even though it is UPSC-oriented; the science and reasoning foundations carry over.

RRB ALP Syllabus 2026 PDF Download (Official vs Prep)

Searching for an rrb alp syllabus 2026 PDF download is the natural next step — but most PDFs circulating online are third-party rehosts that mix outdated patterns. To stay accurate, follow this clearly-labelled hierarchy:

Always cross-check the "last updated" date and the CEN number on any PDF. When in doubt, the version on the official RRB website that accompanies the current recruitment notification overrides every third-party document. Download the official CEN, note the exam-pattern annexure, and keep that single PDF as your reference of truth.

Recommended Books and Preparation Material

A focused, exam-aligned booklist beats a pile of random guides. For RRB ALP 2026, prioritise:

• Quantitative Aptitude: A standard fast-track arithmetic book for shortcuts.
• Reasoning: A verbal & non-verbal reasoning practice book with previous-year RRB sets.
• General Science: NCERT Class 9-10 Science, plus a Lucent-style objective science book.
• Technical (Part B): Your trade’s ITI/diploma textbook + a trade-specific objective question bank.
• Mocks: An online CBT + CBAT mock test series — non-negotiable for this exam.

If you want a quick model for how a clean, well-structured syllabus booklet should read before you build your own notes, the format of a syllabus booklet like this one shows how to compress a sprawling syllabus into a revision-friendly layout — a habit worth copying for your RRB ALP topic tracker.

Common Mistakes RRB ALP Aspirants Make

• Over-preparing CBT 1: It is only a screen; don’t burn months perfecting a stage whose marks are discarded.
• Ignoring Basic Science & Engineering: This Part A section is a huge merit lever and is frequently under-studied.
• Treating CBAT as "can’t be prepared": It absolutely can — timed mock practice meaningfully improves battery scores.
• Guessing blindly: 1/3 negative marking quietly erodes scores; attempt selectively.
• Over-investing in Part B: 35% qualifies — spend the surplus time on Part A and CBAT, which actually decide rank.

Frequently Asked Questions

What is the syllabus of RRB ALP?

The RRB ALP syllabus spans four stages: CBT 1 (Mathematics, General Intelligence & Reasoning, General Science), CBT 2 Part A (Maths, Reasoning, Basic Science & Engineering) and Part B (your trade/technical subject), the CBAT psycho test (vigilance, perceptual speed, attention, memory), and finally Document Verification with an A-1 medical examination.

How many stages are there in the RRB ALP exam?

There are four stages — CBT 1, CBT 2 (with Part A and Part B), the Computer-Based Aptitude Test (CBAT), and Document Verification plus Medical Examination. CBT 1 is a screening test; only CBT 2 Part A and CBAT count toward the final merit.

Is there negative marking in the RRB ALP exam?

Yes, both CBT 1 and CBT 2 have negative marking of 1/3 mark for each wrong answer, so three wrong answers cancel one correct answer. The CBAT (psycho test) has no negative marking, but it rewards accuracy with speed across each test battery.

What is the difference between CBT 1 and CBT 2 in RRB ALP?

CBT 1 is a 75-question, 60-minute qualifying screen whose marks do not count toward merit. CBT 2 is a 175-question, 150-minute test with a merit-counting Part A (100 questions) and a qualifying trade-based Part B (75 questions, minimum 35% to pass).

How is the RRB ALP final merit list calculated?

The final merit is calculated from CBT 2 Part A and the CBAT in a 70:30 ratio — 70% from Part A normalised marks and 30% from CBAT. CBT 1 and CBT 2 Part B do not contribute any marks to the final rank; they are only qualifying. Always confirm the exact ratio in the year’s official CEN.

Is CBAT qualifying in RRB ALP and can it be prepared?

Yes, CBAT is mandatory and qualifying for ALP — you need a minimum of 42 marks in each battery with no community relaxation, and it then adds 30% to your merit. It is a trainable skill: regular timed mock batteries for vigilance, perceptual speed, attention and memory measurably improve your scores.

What subjects are in RRB ALP CBT 1?

RRB ALP CBT 1 has three core subjects — Mathematics (20 questions), General Intelligence & Reasoning (25 questions) and General Science (20 questions) — plus a light General Awareness/Current Affairs component (10 questions), for a total of 75 questions in 60 minutes.

Is the RRB ALP syllabus available in Hindi?

Yes. The RRB ALP CBT 1 and CBT 2 papers are offered in Hindi along with English and several regional languages, and the syllabus topics map directly — गणित (Maths), सामान्य बुद्धि एवं तर्कशक्ति (Reasoning), सामान्य विज्ञान (General Science) and आधारभूत विज्ञान एवं इंजीनियरिंग (Basic Science & Engineering). The CBAT is conducted only in Hindi and English.
