The rail has a smaller cross section than mainline track. This can be represented by using smaller rail than your mainline, for example, code 70 instead of code 83. Here are a few tips for applying ballast that have helped me: If you use cork, sand the edges of the slope so the small stones will adhere better.
The track on a railway or railroad, also known as the permanent way, is the structure consisting of the rails, fasteners, railroad ties (sleepers, British English) and ballast (or slab track), plus the underlying subgrade. It enables trains to move by providing a dependable surface for their wheels to roll upon.

It also helps with drainage, so rain water can drain away rather than pooling, and with preventing vegetation growth, which could destabilise the track and be a hazard for anyone working on the railway. The ballast is packed up to, between and around the sleepers, with a 'shoulder' of ballast piled up at either end to resist side-to-side ...

• Ballast quality and ability to resist crushing forces (ballast degradation is the number 1 cause of ballast fouling) – Some railroads use different track modulus (u) values in design. For example, Spring u may be used for rail bending and ballast depth, but Winter u used for rail seat forces. Other railroads may use a .
A ballastless track or slab track is a type of railway track infrastructure in which the traditional elastic combination of ties/sleepers and ballast is replaced by a rigid construction of concrete or asphalt.
This is because as the ballast layer tends to deform, the grains are restrained by tension generated within the fibres. However, the biggest benefit in the tests carried out in the SRTF was obtained by reducing the slope at the edge of the mound of ballast on which the track sits (termed the "ballast .
