Laying 60 kg/m Rails on Sharp Curves along Guiyang-Nanning Line

Abstract

Abstract

A mechanical analytic model is built to study the lateral force acting on the rail fastenings and the track geometry error in sharp curves during laying 60 kg/m rails in sharp curves. Computation and analysis are made based on a curve with the smallest radius of 177.1 m along Guiyang-Nanning line. The results show that when placing 60 kg/m rails in sharp curves, the track geometry errors are within the allowable limit, and there is no need to take extra measures to strengthen the track structure.
