The book begins with a comprehensive history of railways—how they started during the industrial revolution and how modern high-speed trains have evolved. This chapter sets the stage by highlighting the significance of rail systems globally and regionally.
2. Track Components and Their Functions
This section introduces the primary elements of railway tracks:
- Rails: Types, materials, and wear characteristics
- Sleepers (Ties): Wooden, concrete, and steel types
- Ballast: Functions and properties
- Fastenings: Bolts, clips, and elastic fasteners
Each component is discussed with technical drawings, load considerations, and durability factors.
3. Geometric Design of Railway Tracks
Designing a railway track requires precision and foresight. The chapter explains:
- Track gauge and alignment
- Gradient and curvature
- Superelevation
- Transition curves
These elements ensure smooth rides, safety, and fuel efficiency. The book uses formulas and examples to demonstrate proper design practices.
4. Points and Crossings (Turnouts)
This crucial chapter covers:
- Types of switches
- Crossings and frogs
- Layout of turnouts
- Maintenance of points and crossings
Turnouts are essential for train direction changes, and improper design can lead to derailments.
5. Track Maintenance and Renewal
One of the most practical chapters, it discusses:
- Scheduled and emergency maintenance
- Track renewal methods

- Steam locomotives (historical)
- Diesel-electric engines
- Fully electric trains
- High-speed bullet trains and Maglev technology
Power transmission, tractive effort, and braking systems are also discussed in detail.
7. Railway Stations and Terminals
Covers design and classification of stations:
- Terminal, junction, and halt stations
- Passenger vs. freight stations
- Platform design, foot overbridges, subways
- Urban metro station planning
8. Signaling and Interlocking Systems
A critical safety chapter that includes:
- Mechanical and electrical signals
- Automatic block signaling
- Interlocking principles
- Centralized Traffic Control (CTC)
- Modern innovations like CBTC
9. Railway Accidents and Safety Measures
Highlights reasons for accidents and how to prevent them:
- Human errors, equipment failure, sabotage
- Preventive maintenance
- Modern detection systems
- Accident analysis and emergency response
