Auxiliary rails as a mitigation measure for degradation in transition zones

Publikováno v: Proceedings of The Fifth International Conference on Railway Technology: Research, Development and Maintenance.

This paper studies the effectiveness of adding auxiliary rails as a mitigation measure for degradation in transition zones of railway tracks. More specifically, it investigates the settlement mechanisms counteracted by the additional rails. Results s

Numerical investigation of railway transition zones stiffened with auxiliary rails

Autor: Mehdi Kamali, Hamidreza Heydari-Noghabi, Morteza Esmaeili

Publikováno v: Proceedings of the Institution of Civil Engineers - Transport. 173:299-308

Culverts and bridges are the most common areas on railway lines where abrupt changes of track stiffness can occur. Using auxiliary rails in the transition zone is one option for gradually increasing track stiffness. The study reported in this paper i

The effect of soil improvement and auxiliary rails at railway track transition zones

Autor: P. Chumyen, D.P. Connolly, P.K. Woodward, V. Markine

Publikováno v: Soil Dynamics and Earthquake Engineering. 155

Railway track transition zones are areas where there is a sudden change in the track-ground structure. They include changes between ballasted and slab track, bridge approaches, and tunnel entry/exits. They are often the location of rapid track deteri

Abrupt track vertical stiffness variations along railway tracks can lead to increased dynamic loads, asymmetric deformations, damaged track components, and consequently, increased maintenance costs. The junction of slab track and ballasted track is o
