RRB Technician CBT 2 Syllabus

The RRB Technician CBT 2 is the main examination of the RRB Technician 2027 recruitment. Only candidates who qualify CBT 1 appear in CBT 2. The CBT 2 score is the sole basis for the final merit list. CBT 2 consists of 150 questions carrying 150 marks in 120 minutes, divided into a 100-mark trade-specific technical section and a 50-mark common technical knowledge section (Physics and Chemistry, Computer Applications, and Environmental Science).

CBT 2 Exam Pattern

Trade-Specific Section (100 Questions)

The 100-mark trade section tests core technical knowledge at the ITI and Diploma level for the trade or discipline of the applied Technician post. Navigate to the individual trade syllabus page for the complete topic-level breakdown:

Common Technical Section Syllabus (50 Questions)

The following 50-mark common section applies to all Technician posts in CBT 2:

Physics and Chemistry (20 Questions - Class 12 / Diploma Level)

•        Physics (Class 12 / Diploma Level): Units and Measurement; Motion (kinematics; Newton's Laws); Work, Energy and Power; Properties of Matter (elasticity, viscosity, surface tension); Heat and Thermodynamics (specific heat, latent heat, laws of thermodynamics, Carnot cycle); Sound (wave motion, Doppler effect, resonance); Light (laws of reflection and refraction; lenses and mirrors; Young's double slit; diffraction; polarisation); Electrostatics (Coulomb's Law, capacitance, dielectrics); Current Electricity (Ohm's Law, Kirchhoff's Laws, Wheatstone bridge, power); Magnetic Effects of Current (Biot-Savart, Ampere's Law, force on conductor); Electromagnetic Induction (Faraday and Lenz); AC Circuits (RMS, LCR, resonance, power factor); Semiconductor Devices (p-n junction, transistor basics, logic gates); Modern Physics (photoelectric effect, radioactivity, nuclear reactions)

•        Chemistry (Class 12 / Diploma Level): Atomic Structure (Bohr model, quantum numbers, electronic configuration); Periodic Table (periodicity, s, p, d, f blocks, periodic trends); Chemical Bonding (ionic, covalent, metallic, VSEPR, hybridisation); States of Matter (gas laws - Boyle's, Charles's, Avogadro's; ideal and real gases); Thermodynamics (enthalpy, Hess's Law, entropy, Gibbs free energy); Chemical Equilibrium (Le Chatelier's principle, Kp, Kc); Electrochemistry (electrode potential, Nernst equation, electrolysis, Faraday's Laws, corrosion); Chemical Kinetics (rate law, order, activation energy, Arrhenius equation); p-Block Elements (Groups 15 to 18 - properties, compounds, oxoacids); d-Block Elements (transition metals, oxidation states, colour); Organic Chemistry (reactions SN1, SN2, E1, E2; IUPAC nomenclature; functional groups; biomolecules); Polymers and Chemistry in Everyday Life

Basics of Computer Applications (15 Questions)

•        Computer Applications Basics (Class 10 / ITI Level): Computer components (CPU, RAM, ROM, storage - HDD, SSD; I/O devices; ports); Operating system functions; MS Office (Word - formatting, tables, find-replace; Excel - formulae SUM, AVERAGE, IF, VLOOKUP, charts; PowerPoint - slides, transitions); Internet (browser, search engine, URL, HTTP, HTTPS, email, online safety); File management (folders, file types, copy, move, delete, zip); Network basics (LAN, WAN, Wi-Fi, IP address, router, modem); Cybersecurity (password best practices, phishing, antivirus, firewalls); Binary, octal, hexadecimal number systems and conversion; Logic gates (AND, OR, NOT, NAND, NOR, XOR) - truth tables and Boolean expressions

Environment and Pollution Control (15 Questions)

•        Environmental and Pollution Control (Class 10 / ITI Level): Types of pollution - Air (pollutants: PM2.5, PM10, SOx, NOx, CO, VOCs; sources; health effects; vehicular emission norms BS6; AQI); Water (BOD, COD, DO; sources of water pollution; effects; treatment methods - primary, secondary, tertiary); Soil (pesticides, heavy metals, plastic; remediation); Noise (dB scale; CPCB limits; control measures); Solid Waste Management (classification; 3R principle; composting; sanitary landfill; e-waste; plastic waste rules; biomedical waste); Renewable Energy (solar PV and thermal; wind; hydro; biomass; geothermal; hydrogen; India's renewable targets); Climate Change (greenhouse gases; global warming; Paris Agreement; India's NDC); Environmental Legislation (EPA 1986; Air Act 1981; Water Act 1974; Forest Conservation Act; Wildlife Protection Act; National Green Tribunal); Indian Railways Green Initiatives (bio-toilets; solar energy on trains and stations; LED lighting; rainwater harvesting; ISO 14001; plastic-free stations)

Preparation Strategy

1. Trade Section is the Priority - 100 Marks

With 100 out of 150 marks from the trade section, this determines your Technician rank. Study systematically from NCVT ITI trade theory textbooks and solve previous SSC JE and RRB Technician trade question banks.

2. Elevate Science to Class 12 Level for CBT 2

The Physics and Chemistry in CBT 2 is Class 12 / Diploma level - significantly harder than the Class 10 General Science in CBT 1. Revise NCERT Class 12 Physics and Chemistry, focusing on Electrostatics, Current Electricity, Electromagnetic Induction, Electrochemistry, and Organic Chemistry.

3. Computer and Environment Are Accessible Marks

The Computer Applications (15 marks) and Environment (15 marks) sections are at Class 10 / ITI level and are accessible with focused one-week revision. Do not neglect them as they offer 30 reliable marks.

Frequently Asked Questions

Q1. Is the Technician CBT 2 the same as the JE CBT 2?

They have a similar structure (trade section + common technical section) but are different examinations for different posts. The JE CBT 2 is for higher-level supervisory engineering posts (Level 6); the Technician CBT 2 is for Level 2/5 trade posts. The technical depth is calibrated accordingly.

Q2. Is there Engineering Drawing in Technician CBT 2?

Engineering Drawing is not a separate section in Technician CBT 2 (unlike JE CBT 2 for Civil/Mechanical posts). However, trade-specific drawing knowledge may be tested within the 100-mark trade section for applicable trades.
