Thick Web Switch (TWS) Maintenance: Inspection Criteria & Reconditioning Rules

This video provides an exhaustive, field-ready training masterclass on the engineering design, physical inspection protocols, and joint maintenance rules for Thick Web Switches (TWS) used in modern railway track layouts, specifically focusing on Indian Railways standards. The session is designed for Permanent Way (P-Way) engineers, Senior Section Engineers (SSE), and track maintenance professionals who need to move past basic track adjustments into precision diagnostics. Moving systematically through structural overhauls, the lecture covers how transitioning from conventional overriding switches to a 160mm Thick Web Switch setup drastically cuts down on tongue rail chipping and wheel flange hitting, boosting safety at higher speeds along divergent routes
