Ensuring Safe, Reliable Rail Performance with Advanced Data Acquisition
Rail operators across Australia and New Zealand are under increasing pressure to ensure braking systems perform reliably under all conditions.
From commuter lines to heavy freight routes, train brakes and wheel slide protection (WSP) are essential. They improve safety and efficiency. They also support rolling stock approval.
Accurate testing is no longer optional. It is a core requirement of modern rail engineering.
Why Brake Testing & WSP Validation Matters
Braking systems must operate consistently across a wide range of conditions. Including low adhesion environments such as wet or contaminated track. Poor performance can lead to wheel damage, increased maintenance costs, and, in extreme cases, safety risks.
Effective validation ensures:
- Safe and predictable stopping performance
- Reduced wheel and rail wear
- Reliable traction under varying conditions
- Confidence during commissioning and certification
For operators and manufacturers, this directly impacts both safety assurance and lifecycle cost management.
The Challenge: Capturing Accurate, Synchronous Data
Brake testing is inherently complex. Engineers must capture and match many signals in real time while the vehicle is moving. The vehicle may face vibration, temperature changes, and electrical noise.
These measurements typically include brake pressure, wheel speed, slip behaviour, acceleration, and overall vehicle dynamics. The challenge is not just collecting this data—but ensuring it is accurate, synchronised, and reliable across all channels.
Traditional measurement systems often fall short due to:
- Poor synchronisation between signals
- Susceptibility to noise and interference
- Limited scalability for larger test setups
- Complex and time-consuming configuration
As rail systems become more advanced, the need for high-performance, integrated data acquisition becomes essential.
A Proven Approach Using Dewesoft Data Acquisition Systems
In a recent rail testing project at a certified European test facility, Dewesoft data acquisition systems validated braking performance. As well as wheel slide protection under both controlled and real-world conditions.
While this project was delivered internationally, the engineering challenges it addresses are directly applicable to Australian and New Zealand rail environments.
These systems enable engineers to:
- Capture high-speed data across multiple channels
- Maintain precise synchronisation between all measurement points
- Integrate analogue, digital, and vehicle bus data (e.g. CAN)
- Perform real-time monitoring and post-test analysis
The result is a complete and reliable dataset that supports validation, optimisation, and reporting of braking system performance. For a full technical overview of the measurement setup, sensor configuration, and test method, see the Dewesoft application note.
Recommended Systems for Rail Brake Testing
Dewesoft offers a range of modular and rugged DAQ systems suited to rail applications.
SIRIUS Modular Data Acquisition System
Designed for high-precision measurement. SIRIUS is ideal for capturing voltage, strain, vibration, and other sensor inputs in complex test environments. Its modular design allows systems to scale as testing requirements grow.
KRYPTON Rugged DAQ System
Built for harsh environments, KRYPTON features an IP67-rated enclosure and distributed architecture. Therefore, allowing it to be installed close to sensors on the vehicle. This reduces noise and improves signal integrity in demanding conditions.
DewesoftX Software
DewesoftX provides real-time visualisation, logging, and advanced analysis tools within a single platform. It simplifies test setup while enabling detailed reporting and repeatable workflows.
Application Across Australian & NZ Rail Projects
Although testing frameworks vary between regions, the underlying requirement remains consistent:
Accurately measure, validate, and document braking system performance under real operating conditions.
These solutions are commonly applied in:
- Rolling stock commissioning and acceptance testing
- Maintenance and performance validation
- Brake system development and optimisation
- Wheel slide protection tuning and verification
- Research and specialised testing facilities
They are used to support operator-specific testing requirements, safety assurance processes, and alignment with national rail safety regulations. Such as those governed by ONRSR in Australia, as well as international best practices.

Frequently Asked Questions
What is wheel slide protection (WSP)?
WSP is a control system that prevents wheels from locking during braking, helping maintain traction and reduce wear.
Why is data acquisition important for brake testing?
It allows engineers to capture synchronised, high-speed data from multiple sensors, enabling accurate analysis of braking performance.
Can these systems operate in harsh rail environments?
Yes. Systems such as KRYPTON are specifically designed for rugged, distributed measurement. Especially in environments with vibration, temperature extremes, and exposure.
Do these solutions meet Australian standards?
They are designed to support standards-based testing and are used globally in certified environments. Compliance depends on the specific project and regulatory requirements.
