Technical Seminar at Railtex/Infrarail 2021

Linsinger’s Elvis Kozica will be returning to the Railtex/Infrarail Technical Seminar Theatre, hosted by Rail Business Daily, to present a talk entitled:

Rail milling explained – when to use it and the benefits it can provide

Elvis Kozica, Linsinger.

In his presentation at 13:50 on Wednesday 8 September, the middle day of the show, Elvis will explain how, as both the number of passengers and the freight tonnage moved by rail increases every year, railways are being called upon to deliver an ever-more-reliable service.

Keeping the tracks themselves in good condition is therefore increasingly important – a task that has to be done without closing the railway.

Rolling contact fatigue, caused by the repetitive passing of wheels over the rail head, produces a variety of defects, including squats, head checks and gauge-corner cracking. These incipient defects need to be removed before they grow into larger cracks that can eventually break the rail and, potentially, cause derailments and accidents.

Grinding the rail, to remove the top surface and, at the same time, restore the design profile, is one traditional answer.  However, rail grinders can only remove a thin layer of the surface in one pass, so removing heavy damage requires multiple passes, which slows the process down.

Rail milling, on the other hand, can remove much larger amounts of material, and deeper cracks, in one pass and without producing the sparks that can be hazardous in tunnels and other areas where flammable material is present.

Linsinger is a pioneer of this process, and there are over 70 Linsinger rail-milling machines successfully operating worldwide.

In this presentation, Linsinger’s Elvis Kozica will detail the process, explain the advantages of rail milling and discuss where it can be used to best effect.

To learn more about rail milling and its application, visit Linsinger on stand E17 in hall 12.
