HistoryEarly Railways by GaugeModern Almost Standard Gauge RailwaysNon Rail UseSee AlsoExternal LinksAs railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rails) to be used. Different railways used different gauges, and where rails of different gauge met – a "gauge break" – loads had to be unloaded from one set of rail cars and re loaded onto another, a time consuming and expensive process. The result was the adoption throughout a large part of the world of a "standard gaug…See more on en.wikipedia.orgEstimated Reading Time: 8 minsPeople also search forstandard gauge railway bookingstandard gauge railway kenyastandard gauge meaningstandard gauge trains 1800sstandard gauge trainsstandard gauge metalRailway Track Design AREMA arema.org/files/pubs/pgre/PGChapter6.pdfPDF fileCHAPTER 6 Œ RAILWAY TRACK DESIGN 223 223 curves as D (degrees per 20 meter arc).
