An analytical model for the prediction of thermal track buckling in dual gauge tracks

Abstract

An analytical model for the prediction of thermal track buckling in dual gauge tracks.

The Prospect of Using the Dual Gauge Line for the Ukraine–Hungary Railway Connection

“…However, it is clear that such a main question concerning the reliability of the continuous welded rail, as its stability under the impact of temperature forces, must be solved concerning the presence of four (or three) rails instead of two in the rail-sleeper grid (ladder). For example, such problems have been solved in several scientific papers (Cuadrado et al, 2008;Arbuzov, 2013;Villalba Sanchis et al, 2018).…”

Nonlinear buckling instabilities of interspersed railway tracks

“…This implies that previous studies have slightly overestimated the buckling temperature of ballasted tracks. Although track buckling has been widely investigated [37][38][39][40][41][42][43][44][45][46], interspersed tracks and their inconsistency have never been fully analysed. The previous study of buckling of interspersed tracks has been preliminary studied using linear analysis and found that the interspersed track can improve the buckling strength of the ageing railway track [47].…”

Risk of increasing temperature due to climate change on high-speed rail network in Spain

“…Specifically, during railway construction as well as repair and maintenance track operations, modern rails are welded and fixed at the so-called rail neutral temperature at which rails are unstressed axially. As a result, if the temperature is extremely high, rail expansion can quickly exceed several centimetres, which may cause track damage due to large lateral misalignments (Kerr, 1976;Esveld, 2001;Chapman et al, 2007;Navarro et al, 2015;Villalba et al 2018).…”
