track bed
Where rails rest
The track bed is the foundation structure on which railroad tracks are laid.
It typically consists of layers of gravel, crushed stone, or ballast that support the ties and rails, providing drainage and distributing the weight of passing trains.
A well-maintained track bed prevents shifting and settling, which is essential for safe rail operations.
The term also applies to abandoned rail corridors that have been converted to hiking or cycling trails.
