Jamvanthali Aliabada Railway Line: Commissioner of Railway Safety Conducts 12-Hour Comprehensive Inspection and High-Speed 130 kmph Trial Run

Introduction

In a pivotal development for Saurashtra’s regional transport infrastructure, the Jamvanthali Aliabada Railway Line section under the Rajkot Division of Western Railway has undergone a rigorous 12-hour safety inspection led by the Commissioner of Railway Safety (CRS). As part of the ongoing Rajkot–Kanalus broad-gauge line doubling project, engineering authorities executed a high-speed trial run pushing test locomotives to speeds of 130 km/h. This comprehensive testing procedure marks the final operational validation phase required before the newly laid track can be commissioned for commercial passenger and freight train operations.

The 12-hour statutory inspection encompasses an exhaustive evaluation of track geometry, structural integrity of rail bridges, signal interlocking systems, overhead electrification (OHE) parameters, and automated safety installations. High-speed testing on new railway tracks is far more than a routine ceremony; it is a critical safety assessment designed to observe dynamic interactions between heavy electric locomotives and the fresh track bed at maximum operational limits. Specialized Oscillation Monitoring System (OMS) equipment mounted on test rakes measures physical vibrations, track stability, and lateral movement under extreme speeds.

Once final safety clearances are issued by the Commission of Railway Safety, this key railway section will significantly increase line capacity between Rajkot, Jamnagar, and Kanalus. By removing single-line traffic bottlenecks, eliminating long waiting times at crossing stations, and enabling higher operational speeds for long-distance trains, the successful trial of the Jamvanthali–Aliabada stretch represents a major milestone in modernizing Gujarat’s western rail corridor.
