Rail tracks are a vital component of any railway network. One of the most widely used types of rail track in the industry is the 115RE rail. In this section, we will provide a brief overview of the 115RE rail, including its history, design specifications, and types.

History and development of 115RE Rail

The 115RE rail was first introduced in the United States in the early 20th century. Its name derives from its weight, which is approximately 115 pounds per yard. This type of rail has been widely used in the railroad industry due to its high durability and strength.

Over the years, the design of the 115RE rail has undergone several improvements. Today, it is manufactured using advanced techniques and technologies, which has helped to enhance its strength and durability even further.

Design specifications of 115RE Rail

The 115RE rail is a standard rail that has specific design specifications. It is made from high-quality steel and has a length of 39 feet, 6 inches. The rail has a symmetrical profile and has a head width of 2 5/16 inches, a base width of 4 5/8 inches, and a height of 6 inches.

The rail also has a specific tolerance for its weight and dimensions, which are important to ensure the rail’s proper function and safety.

Types of 115RE Rail

There are two main types of 115RE rail: the plain and the insulated rail. The plain rail is the most common type and is used in most railway applications. The insulated rail, on the other hand, is used in specific applications where electrical isolation is required, such as signaling and traction power systems.

In the next sections, we will discuss the design and manufacturing process of the 115RE rail in more detail.

Dimensions and Tolerances of 115RE Rail

115RE Rail is an important type of rail used in the railroad industry. The dimensions and tolerances of 115RE Rail are critical to ensure its proper function and safe operation. In this section, we will provide an overview of the dimensions and tolerances of 115RE Rail.

Length and Weight Specifications of 115RE Rail

115RE Rail is a type of rail with a standard length of 39 feet and a weight of 115 pounds per yard. The length of 115RE Rail is important for ensuring that it fits properly on the railroad tracks, while the weight of the rail is important for ensuring that it can support the weight of the trains that pass over it.

Cross-Sectional Profile and Other Design Features of 115RE Rail

The cross-sectional profile of 115RE Rail is also an important factor in its function and performance. The head of the rail has a wide, flat surface that provides a stable contact point for the train wheels. The base of the rail is wider than the head and provides a stable foundation for the rail to rest on. The web of the rail connects the head and the base and provides additional strength and stability to the rail.

In addition to its cross-sectional profile, 115RE Rail also has other design features that are important for its performance. For example, the rail is often fitted with bolt holes for securing it to the railroad ties. The rail also has a certain degree of curvature that is important for ensuring that it can be safely and effectively used on curved sections of track.

Tolerances and Deviations of 115RE Rail

The dimensions and tolerances of 115RE Rail are important for ensuring that it meets the required standards for safe and efficient operation. Tolerances refer to the allowable variation in the dimensions of the rail, while deviations refer to any non-conformity or out-of-specification features of the rail.

The American Railway Engineering and Maintenance-of-Way Association (AREMA) sets the standards for the tolerances and deviations of 115RE Rail. The tolerances for the length, weight, and cross-sectional dimensions of the rail are specified in the AREMA Manual for Railway Engineering. Deviations from these standards can lead to reduced performance, increased wear and tear, and safety issues. Therefore, it is important to carefully monitor the dimensions and tolerances of 115RE Rail during production and use.

Manufacturing Process of 115RE Rail

The manufacturing process of 115RE Rail involves several steps to ensure the production of high-quality and durable rail tracks. The following is an overview of the production process of 115RE Rail:

  1. Steel Making: The first step in the manufacturing process is steelmaking. The steel used for the production of 115RE Rail is made by melting scrap metal and iron in a furnace. The molten steel is then refined to the required composition and temperature to achieve the desired properties.
  2. Continuous Casting: The molten steel is poured into a continuous casting machine, which produces the billets of steel. These billets are then rolled into the required shape and size.
  3. Rolling: The billets are heated and rolled into the desired shape and size using a rolling mill. The rolling process ensures that the 115RE Rail has the correct cross-sectional profile and dimensions.
  4. Cutting: Once the rails are rolled, they are cut to the required length using a saw or cutting machine.
  5. Quenching and Tempering: The rails are then subjected to a quenching and tempering process to enhance their strength and durability. This process involves heating the rails to a high temperature and then rapidly cooling them in a water bath. The rails are then tempered to achieve the desired hardness and toughness.
  6. Straightening: The rails are then straightened to ensure that they are straight and free from any bends or twists.
  7. Finishing: The rails are then subjected to various finishing processes to remove any surface defects and to give them a smooth finish. This includes grinding, polishing, and shot blasting.
  8. Testing: The final step in the manufacturing process is testing. The rails are tested for various parameters such as dimensions, weight, hardness, and straightness. This ensures that the rails meet the required standards and specifications.

Quality control measures are taken at every step of the manufacturing process to ensure that the 115RE Rail produced is of high quality and meets the required standards. The use of advanced technology and quality control techniques ensures that the rails are of consistent quality and meet the needs of the railroad industry.
