What Is the RRB ALP Syllabus 2026?
RRB ALP is a technical railway recruitment in which candidates need normal competitive-exam speed, school-level science, basic engineering, trade knowledge, aptitude-test ability and strong medical fitness.
The recruitment is not limited to one written paper. Candidates move through CBT 1, CBT 2 Part A, CBT 2 Part B, CBAT, document verification and the A-1 medical examination.
CBT 1 is a screening stage and its marks are not included in the final panel. CBT 2 Part A is the main scoring written examination. Part B is a qualifying technical-trade test, but failing it ends the candidate's progress even when Part A marks are high.
Students using free classes can combine this article with the complete RRB ALP YouTube preparation guide for CBT 1, CBT 2, technical subjects and CBAT resources.
The latest official CBT 1 syllabus lists Mathematics, Mental Ability and General Science only. General Awareness is not included in the notified CBT 1 subject list.
Avoid copying an old four-subject CBT 1 table containing General Awareness. Prepare according to the current three-area syllabus.
Aspirants who want broader technical and railway guidance can also use the Railway Loco Pilot preparation guide .
RRB ALP Selection Process 2026
RRB ALP CBT 1 Exam Pattern 2026

RRB ALP Subject-Wise Syllabus 2026
The following subject coaches cover the official notified areas. Prepare common topics for CBT 1 first, then add Basic Science and Engineering and trade study for CBT 2.
Mathematics Syllabus
Common preparation area for CBT 1 and CBT 2 Part A
Mathematics becomes easier when students build calculation speed before memorising short tricks. Most topics are school-level, but the examination tests how quickly and accurately they are used.
Revise tables, squares, cubes and fraction-percentage conversions daily. Complete basic arithmetic before moving to advanced geometry and trigonometry practice.
Use the Railway Maths preparation guide for topic-wise classes, speed methods and railway PYQ practice.
Mental Ability and Reasoning Syllabus
Mental Ability in CBT 1 and General Intelligence in Part A
Reasoning is usually scoring when students practise questions independently. The syllabus contains basic verbal logic, relationship questions, diagrams and analytical decision-making.
Solve questions before watching the explanation. Use rough diagrams for direction, relation and Venn-diagram questions, then maintain an error notebook for repeated logic mistakes.
Use the Railway Reasoning preparation guide for concepts, PYQs and timed practice sets.
General Science Syllabus
Physics, Chemistry and Life Science at Class 10 level
The official notification describes General Science as Physics, Chemistry and Life Sciences of Class 10 standard. NCERT-level concepts and their daily-life applications should be clear.
Physics Preparation Topics
Chemistry Preparation Topics
Life Science Preparation Topics
Read the concept first, make short notes and solve MCQs. Revise formulas, scientific terms and common daily-life applications every week.
For Physics concepts and railway-level practice, use the Railway Physics preparation guide .
Basic Science and Engineering Syllabus
Core technical foundation for CBT 2 Part A
This section is different from the Class 10 General Science syllabus. It focuses on basic engineering concepts used across technical trades.
Study the concept with diagrams and practical examples. Revise measurements, electricity, machines, drawing symbols and workshop safety before moving to trade-specific theory.
Use the Railway Technical Subjects preparation guide for branch-wise classes and Basic Engineering support.
RRB ALP CBT 2 Part B Trade Syllabus
Part B is a qualifying trade test based on the syllabi prescribed by the Directorate General of Training. ITI and Trade Apprenticeship candidates answer questions from their own trade.
Diploma and Degree candidates select one permitted trade according to their engineering discipline. All candidates must secure at least 35 percent in Part B, irrespective of category.

RRB ALP Negative Marking 2026
Attempts should be based on calculation and logic rather than random guessing. A high number of doubtful attempts can reduce the normalized score in CBT 1 and CBT 2.
RRB ALP CBAT Syllabus and Test Batteries
CBAT checks cognitive abilities connected with safe train operation. It does not test normal Maths, GK or trade theory. Candidates should understand the test instructions and practise attention, observation, memory and visual decision-making.
Assistant Loco Pilot Test Battery
Current RDSO candidate guidance lists the following five aptitude test areas for Assistant Loco Pilot.
How to Prepare for CBAT
| Ability | Practical Preparation Method |
|---|---|
| Memory | Practise short visual sequences and recall exercises without writing unnecessary notes. |
| Directions | Read the complete instruction before answering and practise multi-step visual directions. |
| Depth perception | Practise figure-position and spatial relationship exercises. |
| Observation | Compare figures systematically instead of scanning randomly. |
| Perceptual speed | Use timed visual matching practice while protecting accuracy. |
CBAT is skill-based. Memorising shortcuts without timed computer practice is not enough. Use the official RDSO examples before relying on third-party test series.
RRB ALP Final Merit Calculation
RRB ALP A-1 Medical Test Pattern
Assistant Loco Pilot is a safety-category post, so medical fitness is stricter than many other railway recruitments. Candidates should check their eyesight and medical suitability before investing months in preparation.
Official Vision Requirements
The RRB notification describes the standards as indicative rather than exhaustive. Final fitness is decided by the Railway Administration according to the applicable Indian Railway Medical Manual.
75-Day RRB ALP Syllabus Completion Timetable
CBT 1 and CBT 2 should not be prepared as completely separate exams. Mathematics and Reasoning overlap, while technical preparation needs more time and should begin before the CBT 1 result.
Simple Daily RRB ALP Routine
Use the Railway previous-year-question guide to add topic-wise PYQs after completing each chapter.
How to Use Mock Tests for RRB ALP
| Preparation Level | Test Type | Correct Use |
|---|---|---|
| Beginning | Topic quizzes | Check basic formula, science and reasoning understanding |
| Middle stage | Subject tests | Build speed and identify weak chapters |
| After common syllabus | CBT 1 full mock | Practise 75 questions in the official one-hour duration |
| After engineering study | CBT 2 Part A mock | Balance common subjects with technical basics |
| After DGT syllabus | Part B trade test | Check whether the 35 percent qualifying level is secure |
| Final stage | CBAT practice | Train every aptitude battery separately with a computer |
Use the Railway mock-test preparation guide for CBT practice, PYQs and mock-analysis support.
