Ballast: what is it and why do we clean and Network Rail

As the ballast pieces grind together over time through normal wear and tear, it creates fine pieces of granite, like sand. When these ‘fines’ combine with water in the ballast, they stick together: this makes drainage more difficult and the ballast less flexible, therefore less

High Output machines Network Rail

With our modern ballast cleaner systems (BCS) there’s a significant reduction in the need for railway workers to be on the track while the work takes place – most operations are controlled from inside the cabs, so this limits exposure to the dangers of diesel fumes, ballast dust and passing trains.

Measuring the strength of railway ballast

It can be seen that for the railway ballast tested here, yielding occurs at an applied stress of about 0.1-0.13 times the 37% strength. In addition, the initial voids ratios after compaction for the larger ballast particles and the specification ballast are slightly higher which may be due to differences in angularity between the large and small particles.

Ballast color suggestion | Model Railroad Hobbyist

The track shows evidence of ongoing maintenance, and the ballast is not a uniform color. In later WP days the ballast was a more uniform dark gray/black from smelter slag, but lighter colors have been added since. Delle siding, a few miles to the east, is a lighter gray and has a more monochrome look, but the ballast isn't as tall.
