JUMO offers a comprehensive portfolio of measurement and control technology for the railway industry. Other than temperature measurement in the undercarriage area and in the water supply, temperature and humidity control also play a key role.

The French JUMO subsidiary based in Metz supplies temperature sensors for the axle bearings of the bogies of the new Alstom Avelia Horizon high-speed trains. The French state railroad company SNFC (Société nationale des chemins de fer français) has ordered 100 of these trains, which will be used from 2023 as part of the TGV fleet, the equivalent of the German ICE series.
