“…Of the many methods to assess vehicle's hunting stability, the vehicle body lateral accelerations were used in this paper. Hunting was defined to occur when the standard deviation of the acceleration of the centre of the carbody, calculated from running over 600 m of track, exceeded 0.13 g [26].…”

“…In straight track, most rail wear is located at the TOR, and the wear rate is much less than that in curved track. For rail in straight track, most researchers focus on rolling contact fatigue (RCF) [25] and hunting (lateral oscillation of a vehicle) instability [26,27]. However, in recent years, there have been more reports of side wear occurring on straight track.…”

“…Unfortunately, in most cases actual contact conditions are quite far from theoretical predictions. One interesting case is represented by so-called "hollow wear" which especially affects the top of the rail of heavy haul lines and significantly alters the stability of the vehicle in both straight and curved track [11]. This kind of wear modifies the original Hertzian conditions into a conformal contact characterized by larger contact patches in which multiple pressure peaks are often present.…”

“…Although this value is commonly considered not so severe for actual operating conditions (Sawley et al [1] reports that in North America the benefit originated by wear removal balances the associated costs when the wheels reach 3 mm hollow), it has to be considered that the profile alteration is localized in a rather narrow region, and this leads to substantial changes in the contact area (even for relatively low loads), which may also lead to achieving a double point contact, as will be shown in detail later.…”
