Discrete Element Modeling of Aggregate Behavior in

This paper describes an aggregate imaging based Discrete Element Modeling (DEM) methodology successfully employed to model both clean and coal dust fouled railroad ballast behavior. Laboratory direct shear box tests were conducted on granite type clean and fouled ballast aggregate samples. The size, shape and angularity properties of the aggregate particles were obtained through image []

coal dust areas, ballast breakdown is generally the greatest contributor to fouled ballast conditions. Ballast breakdown often occurs under track locations where impact loading is most intense. Problems with impact loading in switches, particularly at the frog, are common. Railhead imperfections like engine burns and battered joints may also cause impact loading under traffic. Impact loading

03.07.2009This was due to major maintinence issues with drainage from coal dust fouling the ballast. BNSF had a pretty big derailment not too long ago that was blamed squareley on coal dust fouled ballast. Now the mines and RR's have been experimenting with surfactants being applied to the coal loads to lock in the dust. These liquids would be sprayed on to the loaded cars. I would not rule out

Track ballast (usually crushed stone), as it is known, is another important part of railroad infrastructure. Although it may just look like plain ole gravel this stone plays a vital role in acting as a support base for the railroad ties and rails as well as allowing for proper drainage of water away from the rails (which is why the stone is always sloped downward and away from track).

from crushed ballast and coal fouling from surface spillage, was studied using a large-scale triaxial apparatus. Increasing fouling content (percentage of particles 4.75 mm) resulted in increased plastic deformation of ballast. A content of mineral fouling greater than 5% significantly changed the deformational characteristics of the ballast in high moisture condition (water content 10%

Most coal loading plants clean the coal and then spray some type of oil like compound on them to keep dust down. As for the aerodynamics, I suspect this myth has been busted. The show Myth Busters did a piece on whether or not your tailgate on the pick-up truck should be up or down. The surprise was that it should be up as you got better gas mileage because there was a cushion of air inside

Railroad ballast is an important component of a railroad infrastructure and is produced from durable, crushed granite or trap rock used on railroad tracks across Missouri and beyond. It forms a track bed packed between, below and around railroad sleepers and acts as a support base to the railroad tracks. Whatever your requirements, you 'll find the perfect service-oriented solution to match

Coal dust in ballast reduces water drainage from the track and deteriorates the stability of the track structure. In recent weeks, the primary cause of reduced coal shipments has shifted from railroad repairs to the inability of SPRB mines to load trains. Since the beginning of August, 70 percent of the missed trainloads are attributable to mines unable to load trains for a variety of reasons
