Introduction

Railroad tracks are integral to the transportation infrastructure, enabling the efficient movement of goods and people. The reliability and safety of railroad tracks depend heavily on the fasteners that hold the rails in place. Bolts are a critical component in this system, ensuring the structural integrity of the tracks. This article explores the various types of bolts used in railroad tracks and highlights geotextile solutions provided by Tongyao company.

Types of Bolts Used on Railroad Tracks

Track Bolts

Track bolts are commonly used to fasten the rail tracks to the railway ties or sleepers. These bolts are designed to handle the dynamic loads and vibrations generated by passing trains. Track bolts are typically made from high-strength steel to withstand these pressures.

Switch Bolts

Switch bolts are used in the railway switches or turnouts, where rails change direction at junctions. These bolts need precise installation and regular maintenance to ensure the switch operates smoothly, providing a safe transition for trains moving from one track to another.

Anchor Bolts

Anchor bolts serve as a crucial component for securing the rail to the foundation, particularly on ballastless tracks. Their primary function is to withstand the forces that could displace the rails, ensuring track alignment and stability.

Joint Bolts

Joint bolts are used at the rail joints, where two sections of rail meet. These bolts must be capable of withstanding significant longitudinal forces and are essential in preventing rail buckling and separation. Regular inspection is necessary to maintain their effectiveness.

Importance of Bolt Quality

The quality of bolts used in railroad tracks cannot be overstated. Poor-quality bolts can lead to catastrophic failures, including derailments. High-quality materials, precise manufacturing, and appropriate maintenance protocols are key to ensuring the longevity and safety of rail infrastructure.

Geotextile Solutions by Tongyao

Tongyao company provides advanced geotextile solutions designed to enhance the foundation stability of railroad tracks. These solutions are engineered to improve drainage, reduce soil erosion, and increase the load-bearing capacity of the track foundations, contributing to overall track resilience and performance.
