RRB ALP Syllabus & Exam Pattern 2026: CBT 1, CBT 2 & CBAT Detailed Guide

INTRODUCTION

Aspiring candidates looking to join Indian Railways must master the RRB ALP 2026 Syllabus to clear one of the most competitive engineering-based recruitment drives in the country. For the 2025-26 cycle, with 9,970 vacancies announced, the competition is intense, making it vital to understand the intricate details of the course-like structure of the examination.

The RRB Assistant Loco Pilot (ALP) selection is more than just a job test; it functions like a specialized technical certification course. It evaluates a candidate's proficiency in core streams like Mechanical, Electrical, Electronics, and Automobile Engineering through various CBT stages.

RRB ALP Exam Pattern 2026: Stage-wise Breakdown

The examination process is divided into three primary academic-style assessments: CBT 1 (Screening), CBT 2 (Technical & Merit), and CBAT (Aptitude).

1. First Stage: CBT 1 (Screening Test)

This stage acts as an entry-level qualifying round. The syllabus focuses on foundational knowledge equivalent to the 10th-standard curriculum.

Subject	Questions	Marks	Duration
Mathematics	20	20	60 Minutes
General Intelligence & Reasoning	25	25	60 Minutes
General Science (Class 10 level)	20	20	60 Minutes
General Awareness & Current Affairs	10	10	60 Minutes
Total	75	75	60 Minutes

There is a negative marking of 1/3rd for every incorrect answer.

2. Second Stage: CBT 2 (Detailed Course Assessment)

This is the most critical stage. It is divided into two parts: Part A (for Merit) and Part B (Stream-specific Qualifying).

• Part A: Focuses on Mathematics, Reasoning, and Basic Science & Engineering.

• Part B: Tests your specific engineering trade/stream knowledge.

Section	Questions	Marks	Duration
Part A (Aptitude + Engineering)	100	100	90 Minutes
Part B (Relevant Trade/Stream)	75	75	60 Minutes
Total	175	175	150 Minutes

3. Third Stage: CBAT (Aptitude Test)

Only for those who clear CBT 2. This is a psychometric test assessing memory, observation, and depth perception. You must score at least 42 marks in each test battery to qualify.

Detailed RRB ALP 2026 Syllabus: Stream & Subject Wise

Understanding the RRB ALP 2026 Syllabus requires a deep dive into the technical modules and general aptitude topics.

Mathematics & Mental Ability

These subjects are common across all stages. The focus remains on speed and accuracy.

• Math's: Number System, BODMAS, Decimals, Fractions, LCM, HCF, Ratio and Proportion, Percentages, Mensuration, Time and Work, Profit and Loss, Algebra, Geometry, and Trigonometry.

• Reasoning: Analogies, Coding-Decoding, Venn Diagrams, Syllogism, Data Interpretation, and Analytical Reasoning.

Basic Science & Engineering (CBT 2 Part A)

This is the "core" of the ALP course. It includes:

• Engineering Drawing: Projections, Views, Drawing Instruments, Lines, Geometric Figures, 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, IT Literacy.

  
  

Part B: Relevant Trade Syllabus

Candidates must choose a trade based on their educational stream (ITI/Diploma/Engineering Degree).

• Electrical Engineering: Three-phase motor systems, Light, Magnetism, Fundamental Electric System, Switches, and Plugs.

• Mechanical Engineering: IC Engines, Refrigeration and Air Conditioning, Applied Mechanics, Turbo Machinery.

• Automobile Engineering: Thermodynamics, Materials applying motion, System Theory, Heat Transfers.

• Electronics Engineering: Transistors, Digital Electronics, Networking and Industrial Electronics.

Strategic Preparation for RRB ALP 2026

To excel in the RRB ALP 2026 Syllabus, students must treat the preparation as a professional diploma course.

1. Focus on Part B: Since Part B is qualifying (35% pass mark), don't ignore your technical stream subjects. If you fail Part B, your high marks in Part A won't matter.

2. Master Engineering Drawing: Many students lose marks here. Use standard textbooks to practice symbolic representations.

3. Current Affairs: Stay updated with the 2025-2026 railway budget and national technological advancements.

FAQs: RRB ALP 2026 Syllabus

Q1. What is the weightage of the RRB ALP 2026 Syllabus in the final merit list?

The final merit is calculated by taking 70% of the marks from CBT 2 (Part A) and 30% of the marks from the CBAT (Aptitude Test). CBT 1 is purely a screening test and does not contribute to the final merit.

Q2. Is the RRB ALP 2026 Syllabus different for Diploma and ITI holders?

While the Part A syllabus remains the same for everyone, the Part B syllabus depends on the specific trade/stream you choose. ITI holders take tests in their trade, while Diploma/Degree holders choose a relevant stream like Mechanical or Electrical.

Q3. Does the RRB ALP 2026 Syllabus include negative marking in all stages?

No. Negative marking (1/3rd) is applicable in CBT 1 and CBT 2 (both Part A and B). However, there is no negative marking in the CBAT (Aptitude Test) stage.

Q4. What is the difficulty level of the General Science section in the RRB ALP 2026 Syllabus?

The General Science section in CBT 1 is based on the Class 10 (CBSE) level, covering Physics, Chemistry, and Life Sciences. In CBT 2, it shifts toward "Basic Science and Engineering," which is more technical and application based.

Q5. Can I change my trade subject after submitting the application for the RRB ALP 2026 Syllabus?

Generally, you cannot change the trade chosen for Part B once the application window closes. It is crucial to select a trade that aligns with your educational stream during the registration process.

Conclusion

The journey to becoming an Assistant Loco Pilot in 2026 demands a perfect blend of technical expertise and general aptitude. By thoroughly understanding the RRB ALP 2026 Syllabus and the weightage of each engineering stream, you can prioritize the right modules. Remember, CBT 2 Part A is your ticket to the merit list, but Part B is the gatekeeper you must pass.
