Different Types of Railroad Spikes
Railroad spikes are essential fasteners used to secure rails to ties. Various types of spikes cater to different rail systems and applications. Here are the main types:
1. Dog Spikes (Cut Track Spikes)
- Description: Shaped like a dog’s head, these spikes are used primarily with T-shaped rails.
- Application: They securely fasten T-shaped rails to wooden ties.
- Advantages: Offer high holding strength, especially when driven across the grain of the tie.
2. Screw Spikes
- Description: These spikes have a helical thread that allows them to be screwed into the tie.
- Application: Commonly used in both wood and concrete ties.
- Advantages: Provide strong holding power and can be easily removed and reused.
3. Plate Spikes
- Description: Used with base plates to secure rails to ties.
- Application: Typically employed in heavy-duty rail applications.
- Advantages: Distribute the load more evenly, reducing stress on the ties.
4. Lag Bolts (Lag Screws)
- Description: Heavy-duty bolts used in some rail systems.
- Application: Often used in combination with wooden ties.
- Advantages: Provide excellent holding power and stability.
5. Rail Anchors
- Description: Not traditional spikes but serve a similar purpose.
- Application: Used to prevent rail movement.
- Advantages: Help maintain track alignment and prevent longitudinal movement.
Summary
Each type of railroad spike has specific applications and advantages, making them suitable for various rail systems. Understanding these differences is crucial for effective rail maintenance and safety.
