The latter is especially important, because the ballast shoulder is the main restraint to lateral movement of the track. [8] The ballast shoulder should be at least 150 mm (6 inches) wide, and may be as wide as 450 mm (18 inches). [9] Ballast must be irregularly shaped to work properly The shape of the ballast is also important.

Contribution of Base, Crib, and Shoulder Ballast to the Lateral Sliding ...
The sleeper to ballast interface plays a crucial role in the stability of ballasted railway track, transferring both vertical and lateral loads safely from the superstructure to the sub-base. However, current conceptual models for the behaviour of the interface are incomplete and too simplistic to assess the response of the track system to the loads exerted by modern trains. For example, the ...
