Prefab slab track construction.
Prefab slab track is a concrete trackbed with the rails fastened directly to it, used instead of the gravel ballast of traditional rail construction. It's widely used on newer high-speed lines in China, Japan, and parts of Europe.
How it works
Concrete slabs are manufactured off-site, shipped to the corridor, and set into position where they are aligned to millimeter tolerance.
Why high-speed lines use it
Slab track has higher dimensional stability than ballasted track and requires less routine maintenance over its service life. Ballasted track needs regular tamping and realignment to hold geometry at high speeds; slab track holds its geometry on its own.
What we're engineering
Standard Railroad is building the domestic engineering and manufacturing capability to deploy prefab slab track construction in the United States.
