Mathematical models are extremely limited at modeling ballast, the gravel layer located under railway tracks. Researchers have shown that a large part of the energy introduced by a train passing is ...

RAILWAY AGE, NOVEMBER 2023 ISSUE: Both are essential for a rugged, lasting railway. Welcome to “Timeout for Tech with Gary T. Fry, Ph.D., P.E.” Each month, we examine a technology topic about which ...

The evolution of particle breakdown in railway ballast – the crushed rock under railway tracks to absorb the weight of trains – has been modelled. Sun YiFei from the University of Wollongong led a ...

RAILWAY AGE, NOVEMBER 2023 ISSUE: High-production, computer-driven track machines and inspection vehicles perform one of the most critical of maintenance-of-way functions: keeping ballast in a ...

The sharp, uneven rocks you see beneath railway tracks aren’t there by accident. Known as track ballast, these stones form a crucial layer that keeps the rail system stable, durable and safe, all ...

Network Rail says it is reducing the number of delays caused by engineering works by using a new ballast-laying train. The 'high output ballast cleaner' travels along a stretch of track and replaces ...

Network Rail has placed an order worth £41.7m with Austria’s Plasser and Theurer for an 800m, 3,200 tonne High Output Ballast Cleaner. Network Rail claims the machine, the third such system to operate ...

If you have ever stood by a railway track, you have probably noticed the heaps of small grey stones scattered beneath and around the rails. They might look random, but every single one of those stones ...
