What does Rail Ballast do?
Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the sleepers. It is used to distribute the load from the sleepers, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. (Interestingly, the term “ballast” comes from a nautical term for the stones used to stabilize a ship!) It is essential for ballast to be piled as high as the ties, and for a substantial “shoulder” to be placed at their ends. The latter is especially important, because the ballast shoulder is the main restraint to lateral movement of the track. The ballast shoulder should be at least 150 mm wide, and may be as wide as 450 mm. Ballast Retention systems are designed to prevent ballast from moving away from where it’s needed while still allowing access for maintenance engineers to clean, top up or replace it.
