Typical railroad ballast rock will weigh 1.35 to 1.45 Tons per Cubic Yard (TN/CY). The actual weight will vary depending on source origin of rock used and intended use (speed of trains and track loading weight).

What holds down the rails on railroad track?
Railroad spikes are pounded into the railroad ties and the head of the spike catches the side of the rail. As well, the rail-tie combination is held in place by ballast, consisting of gravel, crushed stone or aggregate on a well packed road bed. .
What is the difference between a ballast and anchor?
A ballast is heavy weights or sand bags to stabilize a ship or air balloon while an anchor is weight that holds the ship or air balloon to float away
How much does US Railroad rail iron weight per meter?

What if your reading material illustrates and discusses a railroad -crossing barricade What is the main purpose of the counter weight?
To counteract the weight of the barricades arm. This way the counter weight will do most of the work when the barricade is lifted.
What the difference between ballast and transformer?
A transformer changes the amperage and / or voltage. It literally "Transforms" electrical energy. A ballast is like a capacitor. Think of a ballast as a short-term battery. It stores power then releases it as needed. A common example of a ballast is on fluorescent lights. Initially, a fluorescent light needs a big blast of energy to excite the gas molecules into emitting photons (light). Then it only needs a small amount of energy to keep the gas molecules in an excited state. However, that power has to be of consistent amperage and voltage. The ballast is designed to do that. The electrical ballast stores energy in the same way that a water ballast stores water for stability. Because the electrical ballast stores far more power than the device it regulates requires, it too provides a kind of electrical stability. That's why you often see a fluorescent light flicker or "lose stability" when the ballast starts to go bad. A transformer transforms voltage and amperage up or down. A ballast provides a stabile power supply.

Why do some railroads have gravel under the rails and some don't?
The "gravel" under the railroad ties is called Ballast and forms the railbed itself. The reason that you dont see ballast under some railsets is because the railroad company has deferring the maintenance on the railbed and grass and vegaetation has grown in between the railroad ties and hides the ballast. A railroad company must spray vegetation killer to maintain the railbed properly. Some railroad companies,usually because of lack-of-money put off maintaining the railbed until the vegetaion has completely obscured the ballast.
What kind of rocks are used as ballast on railroad tracks?
Short answer rocks. That being said railroad track ballast is the cover for the subgrade. Ballast has several functions: * It enables water to drain from the track * It assists in helping control the thermal expansion of continues welded rail * As a train passes the rails it supports the train * it distributes the weight of the train from the track structure to the subgrade * maintains a smooth running surface for the train to run on As ballast becomes contaminated with other materials it looses its ability to do some or all of these jobs.
What is the name of the gravel under the railroad ties?
The gravel under and around the ties is called ballast.
What do you call a heavy weight at the bottom of a yacht?

What is the heavy weight at the bottom of a yacht called?

Why do ships dump ballast water?
Ships dump ballast water to counter any weight they take on, or to decrease their draft.
What is the average depth of gravel under the railroad tracks?
The average depth of the ballast varies from about 12 inches to 18 inches on well maintained lines. It can be more depending on drainage needs. When a railroad wants to raise a track they frequently use more ballast to gain the additional height. On the other hand some poorly maintained lines may have much less ballast. Spur tracks also might not have as much ballast as a main line.

How do fluids help ballast chambers on a submarine?
A submarine actually controls its weight by allowing water to enter or exit hollow chambers in its hull. These chambers are called ballast tanks. Ballast is anything carried in a ship to give stability. When water is allowed to flood into a submarine's ballast tanks, the weight of the submarine increases. When this increased weight exceeds the submarine's buoyancy, the submarine will sink. To allow the submarine to rise, air is pumped into the ballast tanks. The air forces out the water, reducing the weight of the submarine. The submarine then becomes lighter, buoyancy increases, and it floats to the surface. A submarine can also be made to "float" underwater at any depth by adjusting the amount of water weight in its ballast tanks.
