Due to the weaknesses of current radar based ETCS distance measurement devices, such as in harsh weather conditions or on iron bridges, HaslerRail has developed Hasler ? The CORRAIL1000 sensor provides a non-contact, independent tracking bed that directly measures the speed and direction of rail vehicles, with the slide rail as a reference. In order to work even in harsh environments, special care must be taken to ensure robustness and ease of use in maintenance and upkeep. Due to its special structure, it can avoid dirtying the LED and optical components during dust detection and installation of the wheels in the bogie frame for return air, Hasler ? The CORRAIL1000 sensor is insensitive to almost any type of dirt, such as ballast dust, snow, rust, etc
