A railroad tie, also known as a crosstie or sleeper in some regions, is a rectangular support piece used to hold the rails in place on a railway track. These ties are typically made of wood, concrete, or steel, and they are laid perpendicular to the rails, providing stability and support for the track structure. The rails are fastened to the ties using various methods, such as spikes or bolts, depending on the type of tie and the specific requirements of the railway system. Railroad ties are essential components of the railway infrastructure, helping to distribute the weight of the trains and maintain the alignment of the tracks.

Railroad ties are commonly used in landscaping for various purposes due to their durability and rustic aesthetic. Here are some ways they are used:

• Garden Edging: Railroad ties are often used to create borders or edging for garden beds, pathways, or driveways. They provide a strong barrier that helps contain soil and prevent erosion while defining the edges of the landscaping features.
• Retaining Walls: Railroad ties can be stacked horizontally or vertically to construct sturdy retaining walls. These walls are used to hold back soil on sloped terrain, creating terraced areas for planting or enhancing the appearance of a landscape.
• Raised Garden Beds: Railroad ties are popular for building raised garden beds. Their sturdy construction allows them to hold soil in place effectively, creating elevated planting areas that are easier to access and maintain.
• Steps and Stairs: Railroad ties can be used to construct steps and stairs in landscapes, providing stable footing and defining pathways or transitions between different levels of elevation.
• Outdoor Furniture: Some people repurpose railroad ties to create outdoor furniture such as benches, tables, or seating areas. Their robust nature makes them suitable for use in outdoor environments, adding a rustic charm to the landscape.
• Decorative Features: Railroad ties can be incorporated into landscaping designs as decorative elements, such as bordering for ponds, water features, or as part of a garden sculpture or focal point.

When using railroad ties in landscaping, it's essential to consider environmental factors and potential risks associated with treated wood ties, as they may contain chemicals that can leach into the soil over time. Using alternatives such as composite or untreated wood ties can mitigate these concerns. Additionally, proper installation and maintenance are crucial to ensure safety and longevity in landscaping projects involving railroad ties.
