Railway Gauge Expansion in Small Radius Curvature
Conference object (Published version)

In the article a curvature analysis of a three axial bogie of the locomotive type JZ 461 was implemented. The feature of that type of locomotive is that it has a long distance between first and middle axis, which means the distance between the middle and last axis is long too. That feature leads to greater lateral forces during curve negotiation. As a result, the widening of the railway gauge in small radius curvature may appear. The article points that Infrastructure Manager must consider the specialties of vehicle performance and rail type when defines track gauge's curvature.
