FAQs ARTC ARTC

What is rail grinding? Heavy rail grinding removes flaws in the rail surface which can contribute to the creation of “mud-holes”. The rail grinding re-profiles the surface of the rail so there is an even interface between the rail and wheel of the train, which helps make for a smoother ride for trains.

Research methodology for evaluation of top-of-rail

2014-7-31  Top-of- rail friction management uses friction modifiers to control the coefficient of friction within a defined range, and is being used in some North American rail networks with beneficial results. In Australia, there has been limited use of top-of-rail lubrication and where it is applied, it is mainly utilised to improve steering forces and mitigate wheel squeal.

Neutralisation Welding technology :: Trackopedia

After a certain length of a section of line a final weld must be made, called neutralisation of the entire newly installed rail section. The normal lengths of rolled rails (30 m, 60 m or 120 m), are all welded according to the specification and then after a certain length of the newly installed section of track there is a so-called closure weld.
