Retained cutting

A cutting is an excavation of earth material to lower the ground level to allow a railway to remain at the same level. Cuttings help to reduce noise and/or visual impacts associated with trains passing.

A retained cutting is a cutting which is constructed with additional structural support that allows a steeper overall slope gradient than would be naturally possible. This may be a partially-retained cutting, which would include an element of naturally supported slope (usually above the retained element) or a fully-retained cutting, which usually has vertical sides.
