About 115 RE Rail

115 RE rail is a type of rail that has been used in rail track construction for over a century. The designation &#;115 RE&#; refers to the nominal weight of the rail, which is 115 pounds per yard. This weight classification is widely used in the North American rail industry, and is a testament to the strength and durability of the rail.

In terms of physical characteristics, 115 RE rail has a height of 6.25 inches and a base width of 6.25 inches, with a head width of 4.69 inches. The rail has a total length of 39 feet, and weighs approximately 115 pounds per yard. It is made from a special grade of steel that has been heat-treated to increase its strength and resistance to wear.

The historical background of 115 RE rail dates back to the late 19th century, when rail tracks were first being laid across North America. At that time, rail manufacturers were experimenting with different rail weights and dimensions to find the optimal combination of strength, durability, and cost-effectiveness. The 115 RE rail emerged as a popular choice due to its balance of these factors.

Today, 115 RE rail continues to be widely used in rail track construction and maintenance. It is commonly used in heavy haul applications, such as freight and mining, as well as in passenger rail systems. Due to its high weight and strength, 115 RE rail can withstand heavy loads and resist wear and tear over long distances.

In addition to its primary use as a rail track component, 115 RE rail has a range of other applications in the rail industry. It is often used in the manufacture of turnouts, switches, and crossings, as well as in the construction of bridges and other structures that require high-strength steel components.

Technical Specifications of 115 RE Rail

The technical specifications of 115 RE rail are an essential consideration for rail track manufacturers and engineers. These specifications impact the strength, durability, and performance of the rail track system, and can have significant implications for safety and efficiency.

The section modulus of 115 RE rail is 33.36 cubic inches. This property is a measure of the rail&#;s resistance to bending, and is determined by the shape and dimensions of the rail. A higher section modulus indicates a greater resistance to bending and deformation, and is generally desirable in rail tracks.

The moment of inertia of 115 RE rail is 93.7 inches to the fourth power. This property is a measure of the rail&#;s resistance to bending and twisting, and is also influenced by the shape and dimensions of the rail. A higher moment of inertia indicates a greater resistance to bending and twisting, and is generally desirable in rail tracks.

The resistance to bending of 115 RE rail is also an important technical specification. This property is a measure of the rail&#;s ability to resist bending and deformation under heavy loads. 115 RE rail has a high resistance to bending due to its weight and strength, making it a popular choice in heavy haul applications.

When compared to other types of rails commonly used in rail track construction, 115 RE rail has several distinct advantages. For example, 115 RE rail has a higher section modulus and moment of inertia than 100 RE rail, which is a lighter weight rail with a nominal weight of 100 pounds per yard. This makes 115 RE rail more resistant to bending and deformation under heavy loads.

Similarly, 136 RE rail, which has a nominal weight of 136 pounds per yard, has a higher section modulus and moment of inertia than 115 RE rail. However, 136 RE rail is also significantly heavier than 115 RE rail, which can impact its cost-effectiveness and ease of installation.

Manufacturing Process of 115 RE Rail

The manufacturing process of 115 RE rail is a complex and precise operation that requires careful attention to detail and quality control. The process typically involves several stages, including melting, rolling, and finishing.

The first step in the manufacturing process of 115 RE rail is the melting of the raw materials. The materials used to produce 115 RE rail are typically high-quality steel alloys, which are melted down in large furnaces. The molten steel is then poured into molds to create ingots, which are then rolled into billets.

The billets are then heated to a high temperature and passed through a series of rolling mills to shape them into rails. During this process, the billets are gradually reduced in size and shaped into the precise dimensions required for 115 RE rail.

Once the rails have been formed, they are subjected to a variety of finishing processes to ensure their quality and durability. These processes can include heat treatment, straightening, and surface finishing.

Quality control is an essential part of the manufacturing process of 115 RE rail. In order to ensure that the finished product meets the necessary standards of strength and durability, a variety of tests and inspections are conducted at various stages of production.

One common test that is conducted during the manufacturing process of 115 RE rail is a tensile test. This test measures the rail&#;s ability to withstand stress and deformation under tension, and is used to ensure that the rail has the necessary strength to support heavy loads.

Other tests that may be conducted during the manufacturing process of 115 RE rail include ultrasonic testing, magnetic particle testing, and visual inspections. These tests are designed to detect any defects or irregularities in the rail that could compromise its performance or safety.

Installation and Maintenance of 115 RE Rail

The installation of 115 RE rail in rail tracks requires careful planning and execution to ensure that the finished track is safe, durable, and efficient. The process typically involves several steps, including laying out the track, installing the rail, and fastening it securely in place.

There are several different types of fastening systems used for 115 RE rail, including clips, bolts, and welds. Each of these systems has its own advantages and disadvantages, depending on the specific needs of the track and the environment in which it will be used.

Proper maintenance is essential to ensure the safe and efficient operation of rail tracks, and 115 RE rail is no exception. Regular inspections, lubrication, and cleaning are all important to keep the rail in good condition and prevent issues such as wear, corrosion, and cracking.

Inspections should be conducted regularly to detect any signs of damage or wear and tear in the rail or the fastening systems. Lubrication helps to reduce friction and wear on the rail and fastening systems, while cleaning removes dirt, debris, and other contaminants that can cause damage or interfere with the operation of the track.

Regular maintenance is also important for ensuring the safety of rail tracks. Issues such as worn or damaged rail, loose fasteners, or improperly lubricated components can all lead to accidents or derailments, which can have serious consequences.
