- Mastery of axle box design, bearings, and lubrication systems to ensure smooth running and minimize friction.
- Principles of yaw and lateral stability for bogies and their impact on ride quality and track forces.
Braking Systems
- Comprehensive study of pneumatic braking systems, including air compressors, main reservoirs, brake pipes, control valves (e.g., distributing valve), and brake cylinders.
- Understanding the operation of independent (locomotive) and automatic (train-wide) braking systems.
- Principles of dynamic braking (rheostatic and regenerative) and its integration with air brakes for blended braking strategies.
- Analysis of adhesion braking, wheel slide protection (WSP) systems, and emergency braking protocols.
- Practical examples of brake force calculations and stopping distance determination.
Locomotive Carbody and Structure
- Principles of locomotive structural design, including underframe, superstructure, and crashworthiness considerations.
- Understanding material selection for different components, balancing strength, weight, and durability.
- Analysis of draft gear and coupler systems for transmitting tractive and braking forces between locomotives and wagons.
Control, Diagnostics, and Auxiliary Systems
Locomotive Control Systems
- Mastery of microprocessor-based control systems for engine management, traction motor control, and auxiliary functions.
- Understanding distributed power systems (DP) and multiple unit (MU) operation for controlling multiple locomotives in a train.
- Principles of adhesion control systems to maximize tractive effort and prevent wheel slip.
- Overview of train communication systems, including radio and data links for operational control.
On-board Diagnostics and Monitoring
- Techniques for real-time monitoring of locomotive performance parameters, including engine speed, temperature, pressures, and electrical current.
- Interpretation of diagnostic fault codes and troubleshooting procedures for common locomotive system malfunctions.
- Understanding condition-based monitoring principles for predictive maintenance applications.
Auxiliary Systems
- Detailed knowledge of cooling systems for engines, generators, and traction motors, including radiators, fans, and pumps.
- Principles of lubrication systems for diesel engines and mechanical components, including oil filtration and analysis.
