Retrofitting Track Fastenings to Mitigate Stray

Current

As part of ongoing infrastructure improvements, the track section between MUTT and

KLMT on the UP line has undergone retrofitting by replacing the existing Vossloh 336
fastenings with the new and improved 336iw fastenings. This upgrade was executed

using available balance spares from Phase 1 projects, ensuring cost-effective
utilization of resources. The retrofitting work, covering a total stretch of 2 kilometers,

has now been successfully completed. The primary objective of this initiative is to

mitigate stray current interference, which can cause corrosion in adjacent metallic
structures and disrupt signaling systems. Additionally, the 336iw fastenings enhance

the floating properties of the track, improving electrical isolation and reducing leakage

currents.
