With bumps, jolts, vibration, material wear and temperature influences, trains and wagons are subjected to very high loads and stresses. Treo can simulate the loads on and off the track under standardised conditions in the laboratory – and draw the right conclusions from the test results for customers.
“Everyone’s talking about the weather. Not us. We run whatever the weather!” Some might remember this Deutsche Bahn advertising slogan from the 1960s.
At Treo, we may not be able to influence the weather, but with our DIN EN ISO/IEC 17025 accredited test procedures for material testing, environmental simulation, EMC and electrical safety, we can ensure that trains run with the greatest degree of reliability.
Steel railway tracks are exposed to special conditions, and the material must be able to withstand extremely high loads. For many years, we have been working closely with railway companies and suppliers, who are increasingly seeking out our services and expertise.
The railway industry has a diverse range of testing requirements.
One important aspect is environmental simulation tests: in our laboratory, we subject the devices and components installed in or on trains to vibration tests with the shaker. Some tests are carried out at high intensity to ensure that the components can actually withstand the stresses and demands of real-life operation. The testing intensity also depends on where the part is positioned: components on the roof are subject to lower mechanical stress than those lower down on the bogie, where the axles and wheels are attached. Mechanical shock tests also play a key role; significant impact shock can occur when wagons collide, for example during shunting. With climate tests, we check whether equipment and materials can withstand extreme temperatures (for example up to minus 50 degrees Celsius ) or strong temperature fluctuations.
Treo gets trains on track
Modern trains are highly complex assemblies, equipped with many different electronic and electrical parts.
With EMC (electromagnetic compatibility) tests and electrical safety tests, our accredited test laboratory can guarantee the functionality and safety of air conditioning systems, entertainment systems, WiFi routers, switches, information boards, lighting, communication systems and other electronic devices. This is not only relevant for new trains, but also for older models that are being modernised. These models were not originally designed for the installation of high-frequency digital equipment and so potential EMC interference may not have been considered during when they were built. Increasingly, analogue technology is being replaced by digital technology to allow passengers in older trains to see information on displays or on-board systems and provide WiFi services.
Testing standards for rail
An exemplary selection:
- DIN EN 50155
- DIN EN 50121-3-2
- DIN EN 50121-4
- DIN EN 50125-1
- DIN EN 50125-3
- DIN EN 61373
- DB Regulation No. EMV 06
Our engineers can simulate any situation in the laboratory to meet all testing requirements for the railway industry. This is important for our customers from the railway sector, and also for manufacturers from other sectors who may not be familiar with the relevant standards. We advise them on test standards, carry out testing to accompany development, perform accredited tests and prepare test reports so that they can prove that their products are “suitable for railway use”.
With our wide range of services, rail operators and suppliers can get their trains safely on track – fully in keeping with the motto:
“We run, whatever the weather!”
