Railroad ties are essential for keeping trains running smoothly. They’re also pretty popular in landscaping and construction projects.
But if you’re planning to use them, you’re probably wondering: How much does a railroad tie weigh? The answer isn’t as straightforward as you might think. It depends on what the tie is made of (wood, concrete, or steel) and its size.
This article will break down the different types of railroad ties and their weights. We’ll also look at the factors that affect their weight and things to consider when working with them.
How Heavy is a Railroad Tie? A Breakdown by Material
The weight of a railroad tie varies quite a bit, depending on the material it’s made from. Here’s a breakdown of the weight ranges you can expect.
Wooden Railroad Ties
Wooden railroad ties typically weigh between 200 and 250 pounds. However, that number can change depending on the type of wood and how much moisture it contains.
Factors Affecting Wooden Tie Weight
Several things contribute to the weight of a wooden railroad tie:
- Type of wood: Hardwoods like oak and maple are denser than softwoods like pine and cedar, so a hardwood tie will weigh more.
- Dimensions: A longer or thicker tie will naturally weigh more. For example, a 6-foot wooden tie might weigh around 220 pounds, whereas an 8-foot tie could weigh approximately 260 pounds.
- Treatment: Preservatives add some weight, but the difference is usually minimal.
Concrete Railroad Ties
Concrete railroad ties are much heavier than wood. They often weigh up to 1500 pounds!
Reasons for the Increased Weight
Concrete is simply denser than wood, which means it weighs more per cubic foot. Plus, concrete ties are reinforced with steel, which adds to the weight.
Types of Concrete Ties
Pre-stressed concrete ties are commonly used in railroad construction, and they’re a major contributor to the high weight associated with concrete ties.
Steel Railroad Ties
Steel railroad ties aren’t as common as wood or concrete, but they do exist.
Weight Considerations
Steel ties generally weigh somewhere between wooden and concrete ties. The exact weight depends on the design and dimensions of the tie.
Specific Types and Their Weights: Relay Ties, Landscape Ties, and More
The weight of a railroad tie can vary depending on the type of tie it is and its condition. Here’s a closer look at some of the different varieties:
Relay Ties
Relay ties are used railroad ties that can still be used again. They’re typically made of wood, and they weigh close to 300 pounds, give or take a little depending on how worn they are.
Landscape Ties
Landscape ties are often graded depending on how good they look and their overall condition. The grades are typically labeled #1, #2, and #3.
- #1 landscape ties: 150 to 200 pounds
- #2 landscape ties: around 150 pounds
- #3 landscape ties: 100 to 150 pounds
Other Dimensions
Railroad ties are often 7 inches by 9 inches by 8 feet. In this size, they typically weigh between 175 and 195 pounds.
What else affects railroad tie weight?
We’ve covered the basics of material types, but several other factors influence how much a railroad tie actually weighs:
- Moisture Content: Wood absorbs water. A railroad tie that’s soaked through will be significantly heavier than a dry one. The amount of moisture drastically changes the weight.
- Dimensions and Size: This is pretty obvious, but important. A longer, wider, and thicker tie will weigh more than a shorter, narrower, and thinner one.
- Treatment and Preservatives: Wooden ties are treated to prevent rot and insect damage. The preservatives add some weight, although it’s usually a small amount.
- Wear and Tear: Over time, especially with used ties, decay and damage can cause them to lose material. This reduces their weight a bit.
So, while knowing the material type gives you a general idea, keep these additional factors in mind for a more accurate estimate.
Why does railroad tie weight matter?
The weight of railroad ties has a big impact on several areas:
Handling and Transportation
Because of their weight, moving and transporting railroad ties requires special equipment and, often, a lot of people. Concrete ties, in particular, almost always require heavy machinery.
Installation
Installation methods also have to take the weight into account. Workers must use proper lifting techniques and equipment to avoid injuries.
Landscaping and Construction
If you’re using railroad ties for projects like retaining walls or garden pathways, the weight is a critical factor. A tie’s weight is directly related to the structure’s stability and how much weight it can bear.
Safety
Never try to lift a railroad tie by yourself. Always use the right safety gear, like gloves, safety glasses, and work boots.
Summary
As we’ve seen, the weight of a railroad tie isn’t a simple question to answer. It depends on what the tie is made of, how big it is, and the specific type of tie. Wood ties will weigh less than concrete or steel, and longer, wider ties will weigh more than smaller ones.
Knowing the weight of a railroad tie is essential for anyone working with them. Whether you’re moving them, installing them, or using them in a landscaping or construction project, understanding the weight is critical for ensuring safe handling and proper installation.
Because of their weight, railroad ties can be dangerous to work with. Always use appropriate safety precautions, including proper lifting techniques and protective equipment, to prevent injuries.
