TLDR
In this article, a new head-hardened rail has been developed, and a method of improving its weldability is proposed to improve its wear resistance and fatigue crack prevention, and fine pearlitic microstructure is found desirable for both wear-resistance and fatigue-cracking prevention.
Abstract: 
The present situation of high strength rails in Japan is described. Fine pearlitic microstructure is found desirable for both wear resistance and fatigue crack prevention. On the basis of these results a new head-hardened rail has been developed, and a method of improving its weldability is proposed.

Tribological aspects of wheel-rail contact: a review of recent experimental research

P. Clayton
- 01 Jan 1996 - 
TL;DR: In this article, the topical concerns in wheel-rail tribology are highlighted from a heavy haul railroad perspective, and future research needs and the most profitable approach to employ are addressed.

Three-body abrasive wear of fine pearlite, nanostructured bainite and martensite

S. Das Bakshi, +2 more
- 30 Nov 2013 - 
TL;DR: In this paper, the abrasive wear of three metallurgical structures with radically different hardnesses has been investigated for the same steel, and it was found that although the abrasion rates and wear coefficients are not very different for the three states, the mechanisms of ab rasion are quite different.

Dry rolling/sliding wear of nanostructured bainite

S. Das Bakshi, +3 more
- 15 Aug 2014 - 
TL;DR: In this article, the abrasive wear of carbide-free bainitic steel under dry rolling/sliding conditions has been studied and it is demonstrated that this nanostructure, generated by isothermal transformation at 200 °C, has a resistance to wear that supersedes that of other carbide free bainite steels transformed at higher temperatures.

Surface initiated fatigue of pearlitic and bainitic steels under water lubricated rolling/sliding contact

P. Clayton, +1 more
- 01 Dec 1996 - 
TL;DR: In this paper, the rolling contact fatigue behavior of steels that are, or could be, used for railroad rails is reviewed. Butler et al. employed the type of cracks observed in service rails to study the effects of maximum Hertzian contact pressure and slide/roll ratio on fatigue performance under water lubricated conditions.

Effect of microstructure on rolling/sliding wear of low carbon bainitic steels

N. Jin, +1 more
- 01 Jan 1997 - 
TL;DR: In this article, the microstructures of five molybdenum-boron, low carbon, bainitic steels were characterized using transmission electron microscopy and the wear behavior of the steels determined under severe rolling/sliding contact.
