Rail switches, also known as railroad switches or points, are crucial components of railway infrastructure that facilitate the diversion of train traffic from one track to another. These mechanisms enable trains to navigate through junctions, crossovers, and intersections safely and efficiently. Understanding the different types of rail switches and their functions is essential for ensuring smooth and reliable railway operations. In this article, we will explore various types of rail switches and shed light on Veera Technotrec, a leading RDSO approved rail switch manufacturer in India known for its expertise in producing high-quality rail track switches.
Types of Rail Switches and Their Functions
Turnout Switches (Simple and Compound): Turnout switches, commonly referred to as “turnouts” or “points,” are among the most fundamental types of rail switches. They allow trains to diverge from one track to another by guiding the wheels onto a different set of rails. Simple turnouts consist of a single switch, while compound turnouts feature multiple switches, enabling trains to access multiple tracks simultaneously. Turnout switches are crucial for routing trains onto sidings, platforms, or alternate routes.
Thick Web Switches: Thick web switches are designed with robust web sections to withstand heavy loads and high traffic volumes. These switches are commonly used in mainline routes and high-speed rail corridors, where durability and structural integrity are paramount. Thick web switches ensure reliable performance and long service life, making them ideal for critical sections of railway infrastructure.
Fan-Shaped Curved Switches: Fan-shaped curved switches, also known as curved turnouts or diverging switches, are employed in curved track alignments where trains need to navigate smoothly through sharp curves while maintaining optimal speed and stability. These switches feature curved rails that diverge from the mainline track, allowing trains to transition seamlessly onto curved tracks without compromising safety or efficiency. Fan-shaped curved switches are essential for maintaining smooth operations on curved sections of railway lines, particularly in mountainous terrain or urban areas with tight spatial constraints
Crossing Switches: Crossing switches, also known as diamond crossings or frog switches, are used at diamond crossings where two tracks intersect at grade. These switches allow trains to cross over from one track to another without conflicting with opposing traffic. Crossing switches feature carefully designed diamond-shaped crossings to ensure smooth and safe passage of trains, minimizing the risk of derailments or collisions at intersections.
Slip Switches: Slip switches, also known as scissor switches or tandem switches, are specialized rail switches used in yards and terminal facilities. These switches enable trains to bypass tracks or enter sidings without the need for traditional turnouts. Slip switches consist of movable rails that align with adjacent tracks, allowing trains to smoothly transition between tracks without the use of diverging routes.
Spring Switches: Spring switches, also called self-guarded switches or spring frogs, are equipped with springs that automatically return the switch points to their normal position after a train has passed through. These switches enhance operational efficiency by eliminating the need for manual resetting of switch points, reducing the risk of human error and ensuring continuous track alignment.
Derailers: Derailers are safety devices installed at the end of tracks or in storage yards to prevent unauthorized movement of railcars or locomotives onto mainline tracks. When activated, derailers guide the wheels of rolling stock off the rails, effectively derailing the equipment and preventing it from accessing the mainline. Derailers serve as critical safety measures to protect against accidents and unauthorized access to active railway tracks.
Derailing Switches: Derailing switches, on the other hand, are switches specifically designed to intentionally derail trains or rolling stock in emergency situations. These switches are typically installed at strategic locations along railway lines where there is a risk of runaway trains or uncontrolled movement of railcars. When activated, derailing switches divert the train or rolling stock onto a separate track or derailment zone, minimizing the potential for catastrophic accidents and protecting adjacent tracks or infrastructure.
