An empty railroad coal car typically weighs between 30,000 and 40,000 pounds (around 13,600 to 18,100 kilograms), depending on its design and construction materials. The weight may vary based on the type of car and its specific features. Generally, these cars are built to be robust yet lightweight to maximize cargo capacity.
The empty weight of an aluminum coal car is approx 41900lbs.
100,000 lbs
19,712
About 110 tons
A hopper car is a railroad car used to carry loose materials like coal or grain. I know of nothing on an automobile called a hopper.
somewhere in between 44,000 to 45,000 lbs empty
Slightly more if there is moisture in the air.
An engine bumping into a string of coupled railroad cars on a track produces both compression and transverse waives. The engine bumping into the cars creates compressional waves down the string of cars. These waves are taken up by the spring action of the Janney couplers. The law of inertia can cause transverse waves in the coupling motion that can force railroad cars off the track. Think of it this way. If all cars in a cut weight about the same, as one car bumps into the other most of the force is passed down the string of cars. If a empty car pushes into a loaded car too fast the empty car may not have the force to start the loaded car moving. All the force that the empty car has has to go somewhere. The only direction it can go is up or to the side derailing the empty car. That's why there are restrictions on how fast cars can be coupled together. The spring action in the couplers in railroad terms is called slack.
An average fully loaded coal car typically weighs between 100 to 120 tons, depending on its design and the type of coal being transported. These cars are specifically engineered to carry heavy loads, and their capacity can vary slightly based on the specific model and manufacturer. The weight includes both the car itself and the coal it carries.
A coal car can hold between 234,800 to 242,300 pounds.
Depending on the type of rail car, whether loaded or empty, they can range from 30 to 35 tons up to 140 tons (sometimes slightly more)
A typical railroad car is about 32 to 40 inches. railroads now are about as big as a house!
