In the vast network of Indian Railways, the seamless flow of trains relies on well-constructed railway line joints. Let’s explore the process behind these crucial connections:
- Welding Methods:
- Gas Pressure Welding: Heat fuses rail ends, eliminating joint gaps.
- Electric Arc Welding: An electric arc melts metal, creating a strong bond.
- Flash Butt Welding: Intense heat joins rails without external material.
- Thermit Welding: A chemical reaction produces molten metal for seamless joints.
- Construction Challenges:
- Civil engineers survey new rail alignments, akin to explorers charting unknown territories.
- Construction involves translating surveyed paths into actual tracks, often in treacherous terrain.
- Bridges and tunnels pose risks, and engineers have sacrificed their lives to build them.
- Safety and Efficiency:
- Properly welded joints ensure smooth travel, minimizing bumps and disruptions.
- Indian Railways broad gauge (5’ 6″ or 1676 mm) spans vast distances, connecting millions.
