COLOMBO SUBURBAN RAILWAY PROJECT (CSRP), PART III – Focus on KV-Line and Balana-Incline, Concept with Meter-Gauge and Y Steel- Sleepers

The author advocates Meter-Gauge for the upgraded rail-track on the trace of the Kelani-Valley Railway and long welded rails (LWR) on Y-shaped Steel-Sleepers with Pandrol Fast-Clips Rail-Fastening, providing several advantages over a Broad-Gauge track with concrete sleepers and Short Welded Rails (SWR). Less space is needed. Y steel-sleepers tolerate shallow ballast cushion and allow a […]

COLOMBO SUBURBAN RAILWAY PROJECT (CSRP), PART II – an ambitious Project
