Rails were among the first objects of study by neutron diffraction strain measurement and the first experiments were done as early as the late 1980s. This interest is easy to explain: the problem of rail fracturing is critical from the public safety point of view and the penetrating ability of neutrons suggested the possibility of breakthrough experiments and fast progress in this field. It was well-established that residual stresses, both near-surface and interior, played a significant role in the development of defects which led to rail failure. This suggested three distinct approaches of neutron diffraction strain measurement that could contribute to various problems of the rail industry...

In the present paper, we describe recent results in the application of neutron diffraction to the long-standing problems described above...
