Southern Railway has installed 65 acres of filter fabric under its new Spencer yard in North Carolina to overcome problems of soil instability. This is part of the railroad's continuing program of assuring drainage and stability for trackage in both mainlines and yards which started in the 1950s. Southern began to require a densely graded aggregate as a subballast. It is now Southern practice to install fabrics where unstable conditions are experienced and regularly under turnouts and under rail and highway grade crossings. Each application requires a clear knowledge of subgrade, drainage conditions and other factors. The fabric has a long-term benefit in distributing the loads of today's increased tonnages.
