The ballast supports and levels the track. Ballast also helps keep undesirable vegetation from growing in the tracks. 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.
Renamed the Central Maine & Quebec Railway (CMQ), in the first three years the company dumped 48,000 tons (it's an American company) of ballast along the 481-mile-long track. The new ballast, plus some other improvements, allowed CMR to increase the average train speed from just 10 mph, to 25 mph.

maximum track stability the ballast needs to be angular, well graded and compact, which in turn reduces the drainage of the track. Therefore a balance needs to be achieved between bearing capacity and drainage. To elucidate this point, the main geotechnical properties of ballast are briefly discussed in this section.
The ballast we use on our railroads typically consists of granite, quartzite, dolomite, limestone, and trap rock. These stones typically have hard and sharp edges which enable them to lock together under pressure, and the relatively loose nature allows for flexibility as loaded train cars move over them.

Minimum depth of ballast for broad guage is 250 mm and for metre guage it is 200 mm. Width of ballast for broad gauge track is 3.35 meters and for metre guage track is 2.3 metres. Types of Ballast Used in Railway Track
Guys, In a few weeks I will be putting down all track ballast. Problem is, when I look at the YouTubes, all of the ballast being spread looks white-ish in color, or near white. And then, people are trying to paint it darker. I have had the unfortunate luck of having to deal with crushed stone, both limestone and granite, for the past 40 years. …
The standard cross-sectional profile of railway ballast on the track bed is typically triangular. This profile is designed to support the railway sleepers (ties) and evenly distribute the load. The ballast is laid to a specific depth, generally ranging from 150 to 300 mm, depending on the type of railway line and expected load.
Mainline ballast is normally a crushed rock, typically limestone, granite or trap rock, that is in the 2" size. Ballast for concrete ties may be a bit larger, 2-3" size. Ballast in yards or subgrade may be smaller, 1" or so and ballast for walkways may be chat, 1/4-1/2". So the size model ballast you use should be appropriate to that.
Reducing porosity and increasing ballast layer compaction can be the solution for high haul, such as using dynamic track stabiliser. For ballast layer dynamics, the current analysis of the dynamic performance of sleeper-ballast uses simplifications of the track structure, such as scaled ballasted track models and cyclic loading instead of ...

Here are some practical tips and techniques to help you effectively ballast your model railroad track. 1. Choose the Right Material. Selecting the appropriate ballast material is crucial. For most model railroads, fine-grained ballast is preferable as it closely mimics the scale and appearance of real railway ballast.
This paper reviews the criteria, methods and standards for selecting and evaluating ballast materials for railway applications. It also discusses the effects of …
Track ballast forms the track bed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. Ballast bears the load from the railroad ties and holds the track in place as the trains roll over it. The term "ballast" comes from a nautical term for the stones used to stabilize a ship.

Track ballast Down below the trains, below the rails, the tie plates, and the ties, is a lowly yet vital component of railroading — track ballast. While ballast may not be at the top of anyone's list of rail topics, it's literally part of the foundation of railroads, and it can comprise more than 80% of the weight of the track
Fig 4: Moorum ballast. Moorum is formed by the decomposition of laterite. It is available mostly in red color and, sometimes, in yellow. If the track is to be laid on black cotton soil, moorum can be used as a blanketing material or sub-ballast since it prevents permeability of water into the subgrade or formation. Benefits of Moorum Ballast
Droppers must be soldered to track. Step 2. Sometimes, a ballast shoulder can be observed on tracks. Fixing track directly on a baseboard is fine, though adding cork underneath will raise it sufficiently to create a shoulder.
