Proven functionality

Accelerometers have been used in the testing of railway cars during maintenance for decades, and are thus a well-tested technology. However, the patented PMU is the first device ever to use the technology to analyse the status of the railway track and railway vehicles in real time.

During the six years of development the PMU has proven its capability to detect a number of problematic symptoms in both the rolling stock and the railway network. A wheel flat, for example, is detected within one to two seconds.
