Southern-Pacific


Track Base and Ballast

Recycled rock material consisting of crushed jagged concrete and asphalt from a local rock quarry yard was sifted it as depicted by the photos to obtain two grades of material.  The first larger 1/4" to 3/4" material was distributed along both sides and the center of the track to provide additional horizontal and vertical support to allow walking along both sides of the track for future maintenance access without disturbing the soil grades.  The second finer material that was screened thru a 1/4" hardware cloth was used for the visible track ballast in scale and of a color depicting about 80% of ballast used in California.  Additional ballast has been reserved for touching up the right of way from time to time as needed.
