Ballast management machines. The ballast needed for a functioning track network is an important capital asset. Enormous investment costs for substantial quantities of ballast make cost-efficient management of the raw material essential. Economical distribution of ballast over the complete network is a big source of potential savings.
2 · Ballast is the granular material placed and packed below and around the sleepers to transfer load from sleepers to the formation. Ballast in railway track performs the following function: It provides a suitable foundation for the sleepers. It transfers and distributes loads from the sleepers over a larger area of the foundation.

· Abstract. 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 ...
· The term "ballast" in the railway context refers to rocks and boulders used to stabilize tracks and prevent them from shifting. This has been around since the early days of railroads. ... there are other different types of ballast which include gravel, sand, broken stone, bricks and moorum. The easiest way of laying tracks on flat ground is ...
· Abstract Ballasted tracks are the commonly used railway track systems with constant demands for reducing maintenance cost and improved performance. Elastic layers are increasingly used for improving ballasted tracks. In order to better understand the effects of elastic layers, physical understanding at the ballast particle level is crucial. Here, …

· The ballast and its engineering behaviour have a key role in governing the stability and performance of railway tracks. The deformation and degradation behaviour of ballast under static and dynamic loads was studied based on large-scale triaxial testing. The possible use of different types of geosynthetics to improve the performance of fresh
· Type of Ballast Broken Stone. It is the best material to be used in ballast for the railway track. Mostly this type of ballast is used on Indian Railway. Stone to be used as ballast must be hard, tough and nonporous. For stone ballast generally igneous rocks such as granite, quartzite and hard trap are most suitable.
· Tamping is the most widely applied means for ballast track maintenance, and it is necessarily performed for newly built railway lines [15]. It is also helpful for improving track stability and ballast bed performance. In addition, it corrects the ballasted track geometry by lifting up and shifting the rail and sleeper.
· The railway track of permanent nature which handles the normal commercial traffic regularly in called permanent way or permanent track. A permanent way is a combination of rails, sleepers, ballast fixtures, and fastening, etc. this is used to distinguish the finished and permanent track from a temporary track which is laid for temporary work …
Railway ballast also allows for the drainage of water away from the rails. If you have ever seen that stoned is sloped downward and away from the tracks, this is why that is. In centuries past, this type of ballast was used on sailing ships, but the purpose of this material hasn't changed much-if at all-over all of this time.
