Jan 15, 2010Historically, the ballast a railroad used was what was available on line, hence limestone in the south, ganite in the west, cinders or dirt anywhere, etc, as you note. As demands for a better track structure developed, many things changed. Ties got bigger, rail got heavier and the need for a good solid base to build it on got more critical.

Comparison of Coal Dust Fouled Railroad Ballast Behavior—Granite Vs. Limestone. Fouling refers to the condition of railroad ballast when voids in this unbound aggregate layer are filled with fine materials or fouling agents commonly in the form of ballast aggregate breakdown, outside contamination such as coal dust from coal trains, or from subgrade soil intrusion.
Railway ballast is one of the most essential and demanding purposes for crushed stone, as it is vital for railroad infrastructure. It looks very much like regular gravel, but in truth it is much sturdier. It has to be in order to act as a support base for the railroad ties. Railway ballast also allows for the drainage of water away from the rails.

Limestone is by definition a rock that contains at least 50% calcium carbonate in the form of calcite by weight. All limestones contain at least a few percent other materials. These can be small particles of quartz, feldspar, clay minerals, pyrite, siderite, and other minerals. It can also contain large nodules of chert, pyrite, or siderite.

It is utilized primarily for railroad ballast and construction aggregate. The Quarry is located on 525 acres of land and contains approximately 100 million tons of permitted diabase reserves. The facility is strategically located and serviced by Norfolk Southern Rail lines.
passing trains (Figure 1). Rail ballast must interlock to provide this load transfer and track stability. The properties of rail ballast aggregate are therefore very important to the effective load carrying capacity of the rail structure and the subsequent in-service life of the rail track structure. 2.0 Railway ballast

LIMESTONE RAILROAD BALLAST. The load that rail cars place on the track is large. Each axel on loaded rail car places a load of up to 71,500 lbs. on less than an inch of track. The railroad track structure spreads the load to the ballast below. Because ballast material is angular crushed rock, the crushed ballast locks together as a matrix,
The appropriate thickness of a layer of track ballast depends on the size and spacing of the ties, the amount of traffic on the line, and various other factors. Track ballast should never be laid down less than 150 mm (6 inches) thick; and high-speed railway lines may require ballast up to 1 ⁄ 2 metre (20 inches
