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 ...

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 ...

Why are there stones on railway tracks? Today we will look into the answer to this very interesting question. You must have seen an endless pile of stones laid on the railway tracks. What is the ...

SNCF engineers have been using mathematical models for many years to simulate the dynamic behavior of railways. These models have not been able to take into account large portions of the track have ...
