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

The RRB ALP syllabus for 2026 spans three examination stages: CBT 1 (Mathematics, General Intelligence & Reasoning, and General Science), CBT 2 (Part A on Maths, Reasoning, Basic Science & Engineering and General Awareness, plus a trade-based Part B), and the CBAT computer-based aptitude test with 5 psychometric batteries. Questions sit at roughly Class 10 level, both CBTs carry 1/3rd negative marking, and the 2026 revision dropped General Awareness & Current Affairs from CBT 1 while fixing the final merit at a 50:50 weightage between CBT 2 Part A and the CBAT.

Quick answer for busy aspirants:

• Stages: CBT 1 → CBT 2 (Part A + Part B) → CBAT → Document Verification → Medical (A-1).
• Merit: Only CBT 2 Part A and CBAT decide your rank, 50:50. CBT 1 is screening only.
• Negative marking: 1/3 mark in both CBTs; none in the CBAT.
• CBAT cut-off: Minimum 42 in each of the 5 batteries, no relaxation.

If you are preparing for the Railway Assistant Loco Pilot post, this guide gives you the complete, stage-wise rrb alp syllabus 2026, subject-wise topic lists, per-section weightage tables, a deep breakdown of the CBAT psycho test, the full trade-wise Part B syllabus, cut-off trends, a study plan, and a downloadable PDF checklist you can print and tick off. Everything below should be cross-checked against your zone’s official CEN notification before you finalise your prep — this article is a planning companion, not a substitute for the notice.

RRB ALP Selection Process: The 3 Stages at a Glance

The Railway Recruitment Board selects Assistant Loco Pilots through a sequential, elimination-style process. You must clear each stage to be called for the next. Understanding the flow first makes the rrb alp syllabus far easier to plan around.

Marks from CBT 1 are only used for screening. Your final merit is built from CBT 2 Part A and the CBAT, weighted 50:50 — a key change many aspirants still miss. That single fact should shape how much time you give the aptitude test. Note that the CBAT applies to the ALP post specifically; Technician candidates skip it, which is why ALP prep must budget real hours for the psycho test.

RRB ALP Exam Pattern 2026 (All Stages)

The rrb alp exam pattern 2026 is standardised across boards. Both CBTs are objective, computer-based, and carry 1 mark per question with a 1/3rd penalty for wrong answers. The CBAT has no negative marking.

CBT 2 Part A and Part B are attempted back-to-back in a single sitting of 2 hours 30 minutes, so time management across both parts matters. PwBD candidates get compensatory time (scribe/extra time as per rules). Questions appear in multiple languages including Hindi and English, and you can switch the display language inside the exam interface.

RRB ALP CBT 1 Syllabus 2026 (Subject-Wise)

The rrb alp cbt 1 syllabus covers three subjects after the 2026 revision. This is a purely qualifying stage — normalised marks decide who advances at roughly 15 times the vacancies per trade/community. Do not over-invest here, but you must clear the section-neutral cut-off (UR 40%, OBC/SC 30%, ST 25%).

Which subjects are asked in RRB ALP CBT 1?

Mathematics, General Intelligence & Reasoning, and General Science. In the 2026 pattern, Reasoning carries the most questions (25), so it deserves the most practice, followed by Maths and General Science at 20 each.

CBT 1 Mathematics Topics

Number System, BODMAS, Decimals, Fractions, LCM & HCF, Ratio and Proportion, Percentages, Mensuration, Time and Work, Time and Distance, Simple and Compound Interest, Profit and Loss, Algebra, Geometry and Trigonometry, Elementary Statistics, Square Roots, Age Calculations, Calendar & Clock, and Pipes & Cisterns — all at Class 10 level.

CBT 1 General Intelligence & Reasoning Topics

Analogies, Alphabetical and Number Series, Coding and Decoding, Mathematical Operations, Relationships, Syllogism, Jumbling, Venn Diagram, Data Interpretation and Sufficiency, Conclusions and Decision Making, Similarities and Differences, Analytical Reasoning, Classification, Directions, and Statement–Argument & Assumptions.

CBT 1 General Science Topics

Physics, Chemistry, and Life Sciences at the CBSE Class 10 standard — units and measurement, force and motion, work and energy, light, electricity, magnetism, acids-bases-salts, metals and non-metals, carbon compounds, cell biology, human physiology, and environmental science.

RRB ALP CBT 2 Syllabus: Part A and Part B

The rrb alp cbt 2 syllabus part a and part b is where the real merit fight begins. CBT 2 has 175 questions in total split across two parts, attempted in a single sitting of 2 hours 30 minutes.

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

Part A (100 questions, 90 minutes) is the merit-deciding portion covering Maths, Reasoning, Basic Science & Engineering, and General Awareness. Part B (75 questions, 60 minutes) is a qualifying trade test based on your engineering diploma/ITI trade — you only need to pass it (35% for all categories, no relaxation), but you must qualify Part A first for Part B to be evaluated.

CBT 2 Part A — Basic Science & Engineering Topics

This is the highest-weightage block in Part A and the section that separates rank-holders. Topics include: Engineering Drawing (projections, views, drawing instruments, symbolic representation), Units, Measurements, Mass, Weight and Density, Work Power and Energy, Speed and Velocity, Heat and Temperature, Basic Electricity, Levers and Simple Machines, Occupational Safety and Health, Environment Education, and IT Literacy.

CBT 2 Part A — Maths, Reasoning & General Awareness

Mathematics and Reasoning mirror CBT 1 but with slightly tougher questions. General Awareness covers science, current national and international affairs, sports, culture, personalities, economics, politics, and everyday general knowledge. Aspirants who also sit UPSC/State PCS-style prep often keep a monthly current affairs digest handy — Competer’s current affairs magazine (January 2026) is a compact way to cover the current-affairs slice of General Awareness.

RRB ALP CBT 2 Part B: Trade-Wise Syllabus

Part B is drawn from the relevant trade as per DGET (Directorate General of Employment & Training). You choose Part B based on the trade of your ITI/diploma. This is the core of the rrb alp technical/trade wise syllabus. Below is the trade grouping and the core topics for the four most-opted engineering streams.

Part B — Electrical Trade Syllabus

Electrical India, Rolling Contact, Roller Bearings, Motors and Generators, Transformers, Switch Gear, Cables, Magnetism, Basic Electronics, Measuring Instruments, Electrical Circuits, Single and Three Phase Systems, Power Distribution, and Estimation & Costing.

Part B — Mechanical Trade Syllabus

Dimensions, Heat, Engines, Turbo Machines, Kinematics of Machines, Engineering Mechanics, Strength of Materials, Metal Handling, Refrigeration and Air Conditioning, Applied Mechanics, Automobile Engineering, Thermodynamics, Metallurgical Engineering, and Production Engineering.

Part B — Automobile Trade Syllabus

Machine Design, System Theory, IC Engines, Heat Transfer, Thermodynamics, Materials Applied Mechanics, The Theory of Machines, Metallurgical Production Technology, Power Plant Turbines & Boilers, and Automobile electrical systems.

Part B — Electronics Trade Syllabus

The Electronic Devices, Circuits, Digital Electronics, Microprocessors, Microcontroller, Electronic Measurements, Communication Systems, Robotics, Networking and Industrial Applications, and Electronic Instrumentation.

Candidates without an eligible diploma/ITI can appear in Part B against a combined syllabus of relevant trades notified by RRB. Always confirm your exact trade code from the notification before locking your Part B choice — an incorrect trade selection can cost you the qualifying stage even if your Part A merit is strong.

RRB ALP CBAT Syllabus (Psycho / Aptitude Test) Explained

The rrb alp cbat syllabus is the stage most candidates under-prepare — and it now decides 50% of your merit. The Computer Based Aptitude Test evaluates whether you have the psychological and perceptual attributes needed to drive a locomotive safely. It has 5 test batteries, is available only in English and Hindi, carries no negative marking, and you must score a minimum of 42 marks in each battery — with no relaxation for any category.

What is the CBAT test in RRB ALP and how many test batteries does it have?

The CBAT is a psychometric aptitude test with 5 test batteries. It is mandatory for the ALP post (not for Technician). You qualify only if you clear the T-score of 42 in every single battery.

CBAT strategy: because there is no negative marking, attempt every item — but the test is speed-driven, so pace matters more than deliberation. Take at least 10–15 full-length CBAT simulations before the exam; consistency across all five batteries beats a high score in one. Remember there is no re-attempt if you miss the 42 threshold in even a single battery, so build the weakest battery up rather than polishing your strongest.

What is the passing/qualifying mark for RRB ALP CBAT?

You must secure a minimum T-score of 42 marks in each of the 5 test batteries. Fail even one battery and you are out — there is no aggregate or averaging, and no category relaxation on this cut-off.

Negative Marking & Merit Weightage in RRB ALP 2026

Two scoring rules define the rrb alp syllabus 2026 strategy.

Is there negative marking in the RRB ALP exam?

Yes — one-third (0.33) of a mark is deducted for each wrong answer in both CBT 1 and CBT 2. The CBAT, however, has no negative marking, so you should attempt all its items.

Is General Awareness removed from RRB ALP CBT 1 in 2026?

Yes. The 2026 revision removed the General Awareness & Current Affairs section from CBT 1, leaving three subjects — Mathematics, General Intelligence & Reasoning, and General Science — for 75 marks. General Awareness still appears in CBT 2 Part A, so do not drop it from your overall plan.

What Changed in 2026: Before vs After

Here is the clean before/after comparison the top pages scatter across paragraphs.

The takeaway: the CBAT is no longer a formality. Treat it as an equal partner to CBT 2 Part A when you allocate revision time.

Cut-Off Trends & ‘Good Attempts’ Benchmark

While cut-offs vary by RRB zone, trade and category, historical trends give a realistic target. Use these as planning benchmarks, not guarantees.

CBT 1 is generally moderate; CBT 2 Basic Science & Engineering is the difficulty spike. In CBT 2 Part A, roughly 78–85 accurate attempts out of 100 is a genuinely competitive band in high-vacancy zones. Cut-offs are published by each RRB after the result, so treat the figures above as trend-based planning targets and confirm against your zone’s published cut-off once it is out.

Stage-Wise Study Plan & Section Strategy

Map your effort to the weightage. Here is a realistic 4-month timeline tied to the rrb alp syllabus.

Section tips

• Reasoning first: it is the highest-scoring, lowest-risk section — target 90%+ accuracy.
• Maths for speed: master shortcuts for percentages, ratio, time-work and interest to save clock time.
• Basic Science & Engineering: the CBT 2 game-changer — start Engineering Drawing and Basic Electricity early.
• General Awareness: a steady 20–30 minutes daily on current affairs prevents last-minute cramming. Aspirants who also cover economy find structured notes like the Vision IAS Economics notes useful for the economic-awareness questions.
• CBAT: simulate under strict timing — attention and perceptual-speed batteries reward practised reflexes.

Best Books & Study Material Mapped to the Syllabus

Match your material to each section rather than buying one thick ‘combined’ guide. A syllabus-first booklet, a current-affairs digest, and a section-wise practice set cover most of the rrb alp technical/trade wise syllabus and Part A. If you want a clean, exam-board-style syllabus reference to structure revision, a dedicated syllabus booklet keeps every topic in one place, and a monthly current affairs edition covers the General Awareness slice. For the general-economy overlap in Part A’s GA, the economics notes are a handy add-on. Pair these with a trade-specific ITI/diploma textbook for Part B.

RRB ALP Syllabus PDF Download & One-Page Checklist

For offline planning, save the official rrb alp syllabus pdf download from the notification on the concerned RRB regional website (e.g., rrbcdg.gov.in and other zonal RRB portals) and cross-check it against the topic lists above. The syllabus is published inside the detailed CEN (Centralised Employment Notice) as an annexure, so the PDF you want is the notification itself. Print the one-page checklist below and tick off each topic as you finish it.

Common Mistakes to Avoid

• Treating CBAT as optional — it is 50% of merit and cannot be relaxed.
• Ignoring Basic Science & Engineering until late — it is the toughest, highest-weight CBT 2 block.
• Blind guessing in the CBTs despite 1/3rd negative marking.
• Skipping the official trade code check before choosing Part B.
• Still studying General Awareness for CBT 1 (removed in 2026) instead of for CBT 2.
