TL;DR: In this paper, a review of the typical characteristics of the loading conditions for railway track structures, in particular, impact loads due to the wheel/rail interaction, is presented, with particular emphasis on the typical shapes of the impact load waveforms generally found on railway tracks.

TL;DR: The fundamental principle "safety first" is still the key priority in most research today as mentioned in this paper, however, thanks to extensive interface with various customers, research and innovation in practices have shifted from optimizing functional purposes and targets through each stage of life cycle toward modernization, reliability, resilience, and better quality of life.

TL;DR: In this paper, a sensitivity analysis of free vibration behaviors of an in situ railway concrete sleeper (standard gauge sleeper), incorporating sleeper/ballast interaction, subjected to the variations of rail pad properties.

TL;DR: In this paper, a series of repeated impact tests for the in-situ prestressed concrete sleepers were carried out, ranging from a low drop height to the ultimate drop height where the ultimate failure occurred.

TL;DR: In this paper, the authors rigorously review the recent developments on composite sleepers and identify the critical barriers to their widespread acceptance and applications and potential design approaches for overcoming the challenges in the utilisation and acceptance of composite sleeper technologies are also presented.
