Railroad Ballast, Types And Purpose

Track ballast (usually crushed stone), as it is known, is another important part of railroad infrastructure. Although it may just look like plain ole gravel this stone plays a vital role in acting as a support base for the railroad ties and rails as well as allowing for proper drainage of water away from the rails (which is why the stone is always sloped downward and away from track).

Track ballasting made easy - The Railway Shed

Applying ballast manually can take hours on larger sections of track – the trickiest part to get right being the shoulders. Meters of track can be ballasted in seconds using this tool (excluding fixing, but we'll get to that later). The Proses ballast spreader is phisically a little bigger than the competition we've looked at – this means you don't need to fill it as often.

12. Railway track ballast | Geological Society, .

Railway track formations generally consist essentially of a layer of coarse aggregate, or ballast, in which the sleepers are embedded (see Fig. 12.1). The ballast may rest directly on the subgrade or, depending on the bearing capacity, on a layer of blanketing sand. The layer of ballast is intended to provide a free draining base which is stable enough to maintain the track aUgnment with the ...

Why Is Ballast Placed On Railway Track

The appropriate thickness of a layer of track ballast depends on the size and spacing of the ties, the amount of traffic on the line, and various other factors. Track ballast should never be laid down less than 150 mm (5.9 inches) thick; and high-speed railway lines may require ballast up to 1⁄2 metre (19.7 inches) thick. An insufficient depth of ballast causes overloading of the underlying ...
