Long Welded Rail(LWR): Revolutionizing Modern Railway Infrastructure

by

The rhythmic clickety-clack of train wheels passing over rail joints has long been an iconic sound of rail travel. However, modern railway engineering has been steadily working to eliminate this familiar sound by implementing long-welded rail (LWR) technology. This innovative approach to track construction has revolutionized railway infrastructure, offering improved safety, reduced maintenance costs, and … Read more

Railway track systems

by

Early railway tracks were constructed mostly as ballasted railway tracks. The speed of the trains was low so the ballasted tracks have been performing well. However, as the speed of trains became higher the use of more efficient railway tracks was sought after. That led in the 1970s to the first application of ballastless track.  … Read more
