Over Head Line

The Contactless Overhead Line diagnostic and measuring equipment installable on any type of railway Vehicle can measure height, stagger and can be used outside and inside tunnels. The OHL System performs measurements without contact at a vehicle speed up to 350 km/h and can work by day and by night.

Contact wire height: +/-3mm. Contact wire stagger: +/-3mm. Contact wire slope.

The OHL System includes an automatic tracking device system so that each measurement point can be matched with the exact location of the survey position. This locating device will be based on the following technologies: – GPS (used outside tunnels) – Wheel mounted encoder The system will continuously acquire information from all these devices in order to determine the exact position in every situation.
