Ballast is the largest component of the railroad track, which shares a significant part of the entire railroad budget for purchasing, distributing, and maintenance. Ballast grading fundamentally determines its physical and mechanical characteristics. The size of ballast was usually determined by experience with different sizes in the past.
Large-scale track questions and answers. Cleaning track, minimum radius, choosing ballast, and more for G-scale trains ... none of them right or wrong. I prefer using a method similar to that of full-size railroads. ... I am beginning to put down my first garden railroad. In my search for ballast at a local feed & seed store, I asked about ...
I think if you use Google and do a search for ballast that you will find the Military Rail Specification which talks about '3 inch down' i.e. 1mm size in 00 scale. This fits in …
The railway track elements (iron rail bars, concrete sleepers, crushed stone layers, base or ballast layer and the subgrade layer) play an important role to resist the stresses resulting from the movement of trains on this track line, the basic purpose for the railway components to transfer resulting stresses safely to earth's natural layer.
it can be used to reduce total ballast cost or to provide a filter layer between the top ballast and a fine- grained subgrade. Figures 6-2, 6-4, 6-5, and 6-7 show sub-ballast layer.
Railroad ballast is uniformly-graded coarse aggregate placed between and immediately underneath the crossties. The purpose of ballast is to provide drainage and structural support for the heavy loading applied by trains. Aggregate particle shape and size distribution (gradation) are two major considerations in ballasted railroad track design ...
Sand is another good materials for railway ballast, coarser sand is to be preferred to finer sand and the best sand is that which contains a quantity of fine gravel varying in size from 1/8 upwards. Advantages of Sand

Ballast and Coal Use Ballast and Coal for any scale to model realistic railroad track, gravel roads, crushed rock and stones, hopper loads and coal piles. Available in several colors and sizes, you can mix and match for a superior realistic effect.
Railway Ballast is the foundation of railway track and provide just below the sleepers. The loads from the wheels of trains ultimately come on the ballast through rails and sleepers. Ballast plays really important role in tracks foundation and further on works.
Rail Track Ballast is an essential part of any rail construction project. Rail Track Ballast is typically made from crushed granite which has been screened to remove undesirable fines thus creating a hard wearing, free draining and easily cleaned aggregate.
Ballast is crushed stone used to support and drain water away from railroad tracks. Real and model ballast comes in a variety of colors and sizes. Often different stone is used for the ballast around the track and the sub-grade below it.
of ballast size and material for ballast. Based on the conclusions of the research, a change in the current ballast speciÞcation may be appropriate. This paper discusses the merits of such a change, and the historical evidence to support it. 2. ORIGIN OF BALLAST The term ÔballastÕ as a part of railway track originated on Tyneside in the UK.
It ranges from 1/2″ to 2" in size. Primary use: rail bedding Meets NJDOT, NYDOT, and PENNDOT size #3 and #4 specification Other common uses: site entrances, drainage applications Rail Contractors: To order railroad ballast to be delivered by rail, give us a call at 215-295-0777 x254.

Model Railroader is the world's largest magazine on model trains and model railroad layouts. We feature beginner and advanced help on all model railroading scales, including layout track plans, model railroad product reviews, model train news, and model railroad forums.
The sidings use a darker color. I also change grain sizes using HO ballast on the mainline and N scale ballast on the sidings. The N scale ballast looks better with the code 70 and code 55 rail on the sidings. The mainline here is code 100. I mix HO and N scale size grains. Choose a primary color you like for the mainline.
Railroad ballast serves as a bed for railroad tracks and provides track stability, drainage, and support of significant loads carried by railcars. In addition, it deters the growth of vegetation and allows for track maintenance to be performed more easily.
railroad ballast sizing and grading The specified top size and grading (or grain size distribution) of railroad ballast affects its method of production and its performance in track. Both parameters affect any economic evaluation of ballast; as such it is essential to optimize both.
Wilson #4 AREMA 1-1/2" Railroad Ballast is a clean, crushed granite. This Ballast is produced daily at Wilson Quarry to meet the American Railway Engineering and Mining Association (AREMA) #4 Ballast Specifications as well as ASTM C-33 Size #4.
Think CSX for your railroad ballast needs. Did you know that you can fill your need for railroad ballast simply by using CSX? We serve 18 ballast stone quarries on our 21,000-mile network.
Railroad Ballast supports the railroad ties. Because ballast is a large one-size, angular rock, it allows water to drain away from the track. The process of placing the ballast around and under the railroad ties and track is called tamping the track. The ballast supports and levels the track. Ballast also helps keep undesirable vegetation from ...
Sizes: Standard ballast aggregate sizes specified by rail-roads. Applicable Standards: American Railway Engineering Association (AREA) Specification for Prepared Slag, Stone and Gravel Ballast and Federal Specification SS-S- 449: Slag and Stone, Crushed; Gravel, Crushed and Uncrushed (for Railroad Ballast). TECHNICAl DATA
The effects of the ballast on the sound radiation from the rails and sleepers of a railway track have been evaluated from both the acoustic and mechanical views. A one-fifth scale model of the track has been used to carry out acoustic and vibration measurements.
Ballast for railway modellers comes in many sizes and colours. You will need to choose the size dependant on the scale of your model railway, and the colour because of what was used at the location of your railway. Size is really important as over or under size ballast just looks wrong.
