RhB advances multi-point pressure measurement with RET Measurement Solution from Parametric
Chur, Switzerland – 26 May 2025 – The Rhaetian Railway (RhB) has taken a bold step toward operational innovation by independently conducting precision pressure measurements along its trains—powered by Parametric’s advanced technology platform.
Independent Field Measurements Across the Train
Over the course of several nighttime test runs on different train compositions, RhB carried out detailed analyses of pressure fluctuations in the brake lines during the use of both pressure and vacuum brake systems. The aim was to precisely track pressure build-up and release from the driver’s cab to the rear of the train—crucial for optimizing brake response and ensuring system reliability.
At the heart of the campaign was a synchronized cluster of two RET4000 measuring devices from Parametric. Initiated via manual trigger, the measurements enabled high-resolution tracking of pressure propagation throughout the train. The entire process operated autonomously—made possible by Parametric’s sensor platform, which empowers rail operators to run sophisticated measurement campaigns without managing data acquisition complexity.
Platform Technology That Empowers Operators
This independence was key. With Parametric’s modular platform, operators can combine various sensors and execute complex diagnostics on their own terms. The RhB maintained full control of the campaign, using the provided tools to gain actionable insights specific to their operations.
“We delivered the technology; RhB took the lead,” said Andreas Koschak, CEO, of Parametric GmbH. “This collaboration exemplifies how modern railway operators can generate valuable operational data without relying on external service providers.”
A Model for Innovation in the Rail Sector
The success of this initiative underscores the power of combining internal initiative with dependable technology partners. RhB’s approach shows how innovation in the railway industry is increasingly driven by operators themselves—equipped with the right tools to experiment, analyze, and improve.
With this project, RhB sets a compelling example for the industry: precision, autonomy, and innovation can go hand-in-hand to shape the future of rail operations.
