General Description of Electrical Traction System in India
Electric Traction System in India
1. Surface Railway
In India, electrical traction on surface railways is mostly provided via overhead electrification systems. The most popular technology is 25 kV AC, 50 Hz single-phase electrification, which is widely used throughout the Indian Railways network. This system powers locomotives that haul passenger and freight trains, ensuring efficient and dependable operation.
Key Components of Surface Railway System
- Overhead Catenary System (OCS)
- Traction Substations
- Electric Locomotives
2. Metro Railway
India’s metro systems, including those in Delhi, Mumbai, Bengaluru, and Kolkata, use electric traction systems specifically intended for urban mass transit. Depending on the city and line, the electrification system usually consists of 750 V DC third-rail or 25 kV AC overhead catenary systems.
Key Components of Metro Railway System
- Third-Rail Electrification
- Overhead Catenary System
- Electric Multiple Units (EMUs)
