INTRODUCTION – Global Rail Wheel Sensors Market 2021-2026
Rolling and sliding are involved in rail-wheel interaction; the contact surface between the two elements fluctuates from one position to another, resulting in a sinuous movement on the horizontal plane with dynamic load on the rail owing to centrifugal force or rolling stock movement.
So far, studies have shown that the combination of rolling contact, tiredness, and wear is the most harmful consequence. Because of the change in rail radius and increased traction, the point of contact is migrating to the gauge corner.
Without adequate maintenance, the rail profile changes, resulting in increased rail-wheel contact forces and, as a result, more damage propagation.
Railway wheel tread flat is one of the most common flaws in railway wheels, posing a significant risk to vehicle safety.
A novel wheel flat detection system based on a self-made reflecting optical position sensor was created to detect wheel flats dynamically and quantitatively when trains are moving at high speeds.
With the advancement of railway transportation toward faster speeds and heavier axle loads, the wheel-rail contact force grows, putting higher quality demands on the wheels.
Wheel flats are the most prevalent local surface fault in railway wheels over their service life.
Condition monitoring systems are frequently used to examine the health of equipment. Data capture is a critical component of any condition monitoring system.
Estimating the current state and projecting future behavior of the equipment are heavily reliant on the data measurement stage’s characteristics.
Nowadays, condition monitoring has a wide range of applications in the railway sector, and many monitoring systems for inspecting wheel and rail conditions have been presented.
In-service condition monitoring of wheels gives real-time data for maintenance planning, whereas in-workshop examination is typically performed at set intervals.

GLOBAL RAIL WHEEL SENSORS MARKET DYNAMICS
The wheel/rail contact is crucial to the smooth running of a railway network. The wheel tread/rail head and wheel flange/rail gauge corner make contact.
The latter, which occurs mostly in curves, has more severe contact conditions. Because the contact is tiny and supports huge loads, substantial contact stresses are created.
These, in conjunction with contact slip, are principally responsible for driving the processes that result in wheel and rail damage, whether through deformation, wear, or a fatigue process. Multi-body dynamics software may be used to anticipate the wheel/rail interaction characteristics.
Rising urbanisation in developing countries has put a pressure on the existing road, rail, and aviation infrastructure. This has also led to the building of infrastructure for metro-to-suburban connection.
Population expansion in these areas is pushing increased demand for rolling stock as well as supporting infrastructure such as maintenance and services. The need for intra-city mobility solutions is expected to rise as a result of urbanisation.
This market’s rise is due to reasons such as worldwide population expansion along with urbanisation, an increased desire for cleaner and quicker forms of transportation, and economic growth.
Smart railway stations have sprouted up in several developing countries in recent years. Various governments want to improve their rail transportation centers in order to make their railway stations smarter.
In Spain, the International Union of Railways (UIC) and ADIF, the Spanish rail infrastructure management, have joined forces to realise the objective of Smart Stations in Smart Cities.
Furthermore, governments in major cities are focusing heavily on encouraging the development of large-scale public transportation infrastructure, like bullet trains and high-speed trains, to make public transportation more efficient. All of these variables are projected to contribute to growth.
Increasing technical improvements in railway networks and trains, as well as the trend of autonomous technology, are forcing train makers to invest large sums in R&D for the production of light materials for freight trains, passenger trains, and short-distance trains.
Cutting-edge rail network technologies, such as the incorporation of 5G networks and sensor-based traction technology. As a result, the railway sector is prioritising remote monitoring operations, which will increase demand for rail wheel sensors.
A growing number of railway projects, metro projects, and other railway infrastructure projects are expected to drive growth.
In Spain, the Frauscher Wheel Sensor RSR123 is used in a variety of applications that demonstrate its versatility by delivering solutions that address the issues faced by various market segments.
The RSR123 has been used in a variety of projects, including high-speed lines with a top speed of 300 km/h, urban transportation applications like the tram in Barcelona, three-rail projects like the Mediterranean Corridor’s “Castellbisbal – Tarragona” line, and even to trigger hot box detection systems.

RECENT TECHNOLOGICAL TRENDS IN GLOBAL RAIL WHEEL SENSORS MARKET
Almost all commercial electronic train wheel detectors are built on RLC circuits that are placed next to the rail and set to a specific frequency.
When a train passes over the detector, the impedance varies owing to fluctuations in magnetic permeability and flux density caused by the train’s wheel.
This results in detectable fluctuations in the current across the RLC circuit. Other methods suggest a failsafe wheel train detector that use two coils as emitter and receiver. The detector detects the wheels as changes in the magnetic coupling between the coils on each side of the rail.
An optical sensor is a device that transforms light beams into electrical impulses. It may be employed as a smart condition monitoring system in a variety of fields, including civil, mechanical, electrical, and biological, enabling real-time and continuous monitoring.
Many railway data, such as wagon weight, steady speed, and train direction, may be recorded and monitored in real time using an optical sensor.
Another significant feature is rail and wheel health monitoring, which is accomplished through the use of sensors that continuously record strain, vibration, temperature, and acceleration.
An electromagnetic field is created around an adjacent region when an alternating current is applied to an induction wire. When a conductive metal is brought into contact with this electromagnetic field, a current is created in the conducting metal.
The induced current focused potential drop approach is based on assessing the potential drop associated with this type of generated current.
This approach was used to identify surface and sub-surface fractures after many artificial railway wheel flaws were applied. Detecting fatigue damage in the wheel is difficult because of its depth, and monitoring fatigue damage in the wheel is critical due to its sudden fraction.
RAIL WHEEL SENSORS MARKET COMPETITIVE LANDSCAPE
Railway operators, owners, and maintainers want to know about the current state of trains and infrastructure. Unexpected breakdown of crucial components like wheels interrupts regular operations and, in the worst-case scenario, results in derailment.
As a result, in-service monitoring of wheels has received a lot of attention in recent decades. Wheel in-service monitoring is divided into two categories: on-board and roadside measures. Aboard-board measurement refers to techniques of installing sensors on the train.
