Achieving an optimum ballast bed - key to track geometry quality - by means of state-of-the-art ballast distribution and profiling machines

摘要

The ballast bed is the foundation of a railway track and, therefore, it must be constructed and maintained with particular care. The use of state-of-the-art ballast distribution and profiling machines, in conjunction with tamping, is crucial for achieving a technologically correct ballast bed, as well as a high track geometry durability, in an efficient and cost-effective manner and, thus, optimising the life-cycle cost (LCC) of the railway track.
