    <description descriptionType="Abstract">&lt;p&gt;Wear is a natural phenomenon that exists when two bodies, which are in contact, perform&lt;br&gt;
a relative motion; this is also true for the wheel and rail of a railway vehicle. This wear is&lt;br&gt;
mainly dependent on the type of material they are made of. There is a tolerable level of&lt;br&gt;
wear that is safe to the railway operation. Once this critical wear level is reached, it is&lt;br&gt;
mandatory to re-profile the wheel, grind the rail. However, after some time it will be&lt;br&gt;
worn out to the level it can no more be used and the whole system must be replaced with&lt;br&gt;
a new one. This indicates that there is a need to focus on the wear properties of wheel and&lt;br&gt;
rail materials in order to secure a safe and sustainable railway operation.&lt;/p&gt;</description>
