From Trees To Tracks: Production Process
The journey from trees to tracks is a fascinating one. Rail road ties, crucial for supporting the rails, begin as trees in dense forests. Let’s explore this transformation, charting the course from raw timber to the heavy, sturdy ties that crisscross our nation’s landscape.
Harvesting Timber
To begin, special teams select trees suitable for railroad ties. These trees are usually hardy species like oak or pine that can handle heavy loads. Harvesters then cut down the trees with precision and care.
- Selection of the right species
- Cutting down trees with expertise
- Transporting logs to processing facilities
Creation And Treatment
Once at the mill, the raw logs transform into ties. Through a process of sawing and shaping, logs become uniform in size. Afterward, they undergo a vital treatment process.
- Sawing logs into tie dimensions
- Shaping to ensure uniformity
- Pressure treating with preservatives
Preservatives, like creosote or copper azole, are essential. They protect the wood from decay, pests, and weather. As a result, ties gain longevity and durability, ready to support the weight of countless trains.
| Length | Width | Height | Weight |
|---|---|---|---|
| 8.5 feet | 9 inches | 7 inches | 200-300 lbs |
In conclusion, each railroad tie starts as part of a tree and, after a detailed harvesting and manufacturing process, becomes a key component of the railway infrastructure. Understanding this journey sheds light on the importance of each tie that supports the tracks we travel on daily.
