Importance of Springs in the Rail Industry

The rail industry is one of the oldest forms of transport and our springs have played a crucial role in ensuring the proper functioning and safety of various spring components for trains for hundreds of years.

Train suspension technology requires springs to absorb shock and vibration, to distribute loads and to stabilise the rail system, delivering a smooth and efficient operation. With spring manufacturing for railways starting in our formative years in 1852, we have been at the forefront of innovation and manufacture for the rail industry’s springs for decades.

Spring Design for the Rail Industry

Spring design for rolling stock starts with consultations; establishing drawings to meet precise specifications and designing prototypes and samples that evolve as the product design process evolves. Railcar performance handling assessments, technical reviews, safety testing and failure analyses collaborate to direct the demands of the precision spring and secure innovation in rail spring design to achieve the peak performance befitting the trains functionality and environment.

Performance

Maximising the potential of a spring by delivering exceptional design, development and manufacturing production processes is a key part of our customer experience methodology. It is also the winning performance formula behind a rail spring component’s success. Our audited, tested, recognised and reliable multi-stage manufacturing process guarantees the competitiveness and quality of your product.

Durable

The repetitiveness of the work function of a spring is key to understanding the performance demands on that spring. It is also the jumping off point for our engineers and material scientists to develop a rail spring product that secures a lifespan that excels amongst the competition.

Precision

Our state-of-the-art spring manufacturing technology, across the very latest and widest range of large-scale hot and cold coiling CNC spring coiling machines, coupled with the most advanced spring manufacturing processes and expert engineers, establishes us as leading railcar spring manufacturers, providing the highest quality precision springs.

Materials

The most distinguishing properties of rail spring materials are mechanical strength and elasticity. The four key components when considering material choice are chemical composition, surface property, tensile strength and size. These essential elements build the structure from which our engineers deliver spring customisation for the rail industry, to meet the demands of the application of springs within the rail industry and to optimise the purpose and performance.

Rail Applications for Springs

Delivering high-speed rail spring solutions across passenger train spring systems to freight car springs, heavy-duty rail springs play a vital role across many applications.

Suspension Systems

Springs are integral components of a railway vehicle suspension system. They absorb shocks and vibrations, provide a smoother ride for passengers and protect the train's structure from excessive wear and tear.

Buffers and Couplings

Coil spring technology is used in buffers and couplings between railcars as the railroad springs manage the impact and forces during coupling and decoupling operations, preventing damage to the rolling stock.

Weight Distribution

Springs assist in distributing the weight of the train evenly, especially in cases of uneven loading or on uneven tracks. This is crucial for maintaining stability and preventing derailments.

Door Mechanisms

Tension springs and compression springs are also commonly used in the door mechanisms of trains. They assist in the smooth opening and closing of doors, contributing to passenger safety and comfort.

Braking Systems

Compression springs are a crucial part of braking systems in trains. They contribute to the efficient operation of brakes, helping to control the speed of the train and ensuring safety during stops.

Shock Absorption

Springs are employed in various components to absorb shocks and vibrations generated during train movement. This not only enhances passenger comfort but also protects the train's equipment and structure.

Maintenance & Reliability

Spring maintenance for trains is essential, contributing to the overall reliability of rail systems. Regular inspections and replacements of worn-out springs are essential to prevent failures and disruptions in rail operations.

Dampening Systems for Rail Springs

Springs are employed in rail joints and fasteners to reduce vibration noise and to maintain the necessary tension and ensure a secure connection between rail segments. This helps in preventing track misalignment and ensuring a stable track structure.

Engineering & Capabilities

Matching our customers world-class performance expectations with advanced production technology and leading expertise, our technical, quality, engineering and production teams enjoy partnerships with leading rail industry suppliers and with OEM’s.

The majority of our projects involve spring customisation for the rail industry with the design, development, innovation and manufacture of locomotive suspension springs shared through the expertise of our hot coiling and cold coiling spring teams in the UK, Sweden & Finland.

Precision Custom Springs

With our first class engineering and quality teams, technologies, manufacturing processes and advanced CNC spring coiling machines, we deliver an exceptional bespoke spring design and manufacturing service. Continual investment in our facilities and services keeps us at the leading edge of precision spring manufacturing. This allows us to guarantee the maximum potential out of our springs through our expertise and technical analysis on the extreme stress boundaries of material capability and spring design.

The Process

Collaboration is key and the start point of all spring design is the consultation between our technical teams and the customer. Technical designs advance through quality teams and engineers before entering the prototype phase, sample provision, testing and then mass production.

Precision Manufacturing

We’re leaders in our field because we manufacture from the highest quality wire and feature the most advanced coiling and cutting technology. This results in us excelling at spring manufacturing standards within the rail transport industry, delivering spring solutions that deliver the right product for the right application and guaranteeing uniformity and precision from the first spring to the last.

Heat Treatment

An essential part of the manufacturing process, heat treatment removes residual stress introduced to the material during the coiling process. The treatment stabilises the springs dimensions for greater accuracy and increased fatigue life and our oven facilities use forced convection technology to ensure the material is uniformly heat treated from surface to core. Our larger transport industry springs (such as for locomotive suspension springs), using a wider wire diameter, require a hot winding process as the extreme heat allows large scale wire diameters to be coiled.


The process of heating up wire to approximately 900 degrees celsius, quenching in oil and tempered to complete the heat treatment, allows the spring material to be coiled to the specifications required.

Quality Control

Our quality management systems conform to ISO 9001, ISO 14001 and ISO 45001 and our teams are experts in their field. Our global network of quality engineers ensure our rail spring products meet the quality standards required by the design and are the one stop shop for quality control and spring manufacturing standards within the rail industry.
